sixth. Abdomen considerably shorter than the -wings. 

 The male terminalia, moderately conspicuous and pro- 

 truding but not large, are partly rotate and are of the 

 open type. The lateral gonopod does not enclose the 

 cavity along the true ventral aspect as it does in related 

 Laphriini genera. Also the bowl of the epandrium is 

 more shallow and has a narrow, medial fissure-like line. 

 Gonopod apically with three slender, toothed prongs 

 or processes. Hypandrium small, short and fused to 

 the gonopod.

Genus Ichneumolaphria Carrera 



Ichneumolaphria Carrera, Arq. Mus. Nac. Rio de Janeiro, vol. 

 41, p. 115, 1951. Type of genus: Ichneumolaphria zikani 

 Carrera, 1951, by original designation. 



The following is Carrera's description in translation : 



Head wide, a little more than two times the size of the eye. 

 Vertex deeply excavated and wider and toward the front re- 

 duced on account of the proximity of the ocellar callosity to the 

 base of the antenna. Ocellar callosity with a pair of bristles. 

 The antennae are attached over a large pilose salience. First 

 segment cylindrical and almost five times the length of the 

 second segment that is more or less quadrangular. Third seg- 

 ment compressed in the sides with the shape of a strip (tiro), 

 very long and almost four times the combined length of the 

 first two segments. Face inclined backward, with pile on the 

 callosity which bears the antenna, on the ocular margins and 

 in the buccal border. Proboscis compressed laterally, fine and 

 long. Palpus small. Thorax more narrow than the head; 

 prosternum fused to the propleuron, practically without 

 bristles. There is only one presutural bristle and others on 

 the posterior margin of mesopleuron are very fragile; meta- 

 pleuron with long pile. Scutellum without bristles but with 

 short, marginal pile ; lateral callosity of postscutellum bare. 



Legs : Anterior femur and the middle femur normal, the 

 posterior femur clavate. The tibiae are straight, the posterior 

 tibia slightly curved toward the base. Basitarsus of anterior 

 and middle legs as long as the three following segments ; basi- 

 tarsus of hind leg as long as all remaining segments. Claws 

 small, pulvilli as long as the claws. Wings large and longer 

 than the abdomen. The first and fourth posterior cells and 

 anal cell are all closed and bear a long petiole. Fourth pos- 

 terior cell sharp at apex. Alula small. Abdomen not coarctate. 

 Lateral bristles present only on the first segment. Genitalia 

 of female conical.

Genus Alipiolaphria Carrera 



Alipiolaphria Carrera, Arq. Mus. Nac. Rio de Janeiro, vol. 41, 

 p. 116, 1951. Type of genus : Alipiolaphria mirandai Car- 

 rera, 1951, by original designation. 



The following is Carrera's description in translation : 



Head more narrow than the thorax, and approximately as 

 large as one and one-half times its own height. Front short, 



with long bristles along the ocular margins; ocellar callosity 

 with long bristles. Face salient from the base of tie antenna 

 to the buccal border and covered with long bristles on the whole 

 extent. Face as wide as three-fourths the width of one eye, 

 its sides almost parallel. Proboscis small, not of great length 

 laterally, more or less cylindrical and with a small dorsal ridge 

 present. Palpus one-third the length of the proboscis; second 

 segment fusiform. Antenna situated near the top of the head 

 and at the upper fourth of the eye when considered in profile ; 

 the first segment is two times the length of the second segment : 

 the third segment is fusiform and is as long as the two basal 

 segments united ; the first two segments bear dense pile. 



Thorax: The pronotum and propleuron with long pile; pro- 

 pleuron connected to pronotum. Mesonotum with short pile; 

 lateral and dorsocentral bristles are developed posteriorly. 

 Scutellum with four pairs of marginal bristles. The lateral 

 callosity in the region of the postscutellum is without hair; the 

 pleuron has bristles in the posterior margin of the mesopleuron 

 and metapleuron. Legs: Femora of normal thickness; tibiae 

 straight and a little smaller than the femora ; tarsi a little larger 

 than the tibiae. Bristles of legs small and thick; pile short; 

 claws sharp, pulvilli large, empodium developed. The wings 

 are a little larger than the abdomen. The first posterior cell 

 is open ; fourth posterior cell and anal cell closed and stalked. 

 The anterior crossvein is situated a little past the middle of 

 the discal cell. Abdomen as large as the thorax, with parallel 

 sides ; lateral bristles present Genitalia small and subventral.

Genus Anisosis Hermann 

 Figures 246, 609, 1257, 1266, 2112, 2160 



Anisosis Hermann, Ent. Mitt., vol. 3, p. 130, 1914. Type of 

 genus: Laphria phalaris Osten Sacken, 1882, by original 

 designation. 



Rather large, slender flies; the thorax elongate and 

 slender and the abdomen as wide as the mesonotum. 

 Though partly dark in color, they tend to be largely 

 brownish yellow, especially on the face, antenna, legs, 

 wings and on parts of the thorax and abdomen. They 

 are covered often with considerable golden pollen. 

 Wings frequently tipped or margined with blackish. 

 The elongate, oval, third antennal segment has a minute, 

 visible spine from the apical tip. The bristles are gen- 

 erally weak but the abdominal tergites have conspicu- 

 ous lateral bristles and metanotal pile or bristles are 

 absent. Length 18 to 22 mm. 



Head, lateral aspect : The face is short dorsally, 

 gradually becoming a little more produced on the lower 

 portion. While the lower face is rather prominent most 

 of it is due to the recession of the eye. It is gently con- 

 vex and retreating below. The eye is strongly recessive 

 anteroventrally beginning at the upper third. The oc- 

 ciput on the upper third is obliterated, the exposed part 

 due entirely to the recession of the eye. Pile of occiput 

 dense, stiff, bristly and rather long on the ventral third. 

 Extending from the middle to the vertex, the pile is al- 

 most wholly replaced by stout bristles, of which there 

 are at least 12 on each side, all arising rather far from 

 the eye margin. Proboscis directed forward and con- 

 siderably longer than the face ; it is rather strongly swol- 

 len laterally at the base; it has an oblique ridge reach- 

 ing from above to the middle of the ventral margin and
