Abdomen of normal form ; second tergite distinctly longer than first, 

 third half as long as second, fourth and fifth equal and somewhat 

 longer than second, sixth shorter than second ; ovipositor barely more 

 than a third as long as abdomen. 



Head and thorax yellow with black markings as follows : Vertex, 

 middle of frons, upper occiput, and upper posterior orbits; antennae 

 except scape and pedicel ; a broad stripe on each lobe of mesoscutum 

 confluent behind with the prescutellar spot, the lateral ones reaching 

 the lateral margin of the mesoscutum; oblique impression of meso- 

 pleurum ; lateral area of scutellum and its apex ; postscutellum ; band 

 in basal constriction of propodeum and metapleura, and three broad 

 ir^tripes on propodeum confluent with basal band; a large, irregular 

 spot nearly encircling the hind coxa at base ; trochanter and trochan- 

 tella largely ; basal and subapical diffused bands on hind femur ; hind 

 tibia, excejDt reddish stain below, and hind tarsus; all coxae and 

 trochanters, except as noted, and apices of femora yellow ; front and 

 middle legs otherwise testaceous ; middle of hind femur ruf o-piceous ;

EIPHOSOMA SEPTENTRIONALE Brues 



In the original descriptions of this species, Brues states that the 

 palpi are 4-jointed without specifying to which palpi he refers and 

 also that the sixth tergite is as long as the second. If the maxillary 

 palpi have only four joints, this is abnormal; and it seems most 

 ])robable that the statement in regard to the sixth tergite must be 

 due to the omission of a word, such as " half " or " one-third." 



EIPHOSOMA BATATAE. new species 



In Cockerell's key ^ runs to couplet 5, where in size it agrees some- 

 what better with sejytentrionale Brues than wdth viexicmimn Cresson, 

 although the infuscation at the apices of the wings is barely discern- 

 ible. In Tiiexicanum., the eyes are extremely large even for the genus 

 and bulge all around beyond the general contour of the head, which 

 is true neither of tlie present species nor of septentrionale. 



Female. — Length, 15 mm.; antennae, 7 mm.; ovipositor, 5.5 mm. 

 Head shining, coarsely punctate, sides of face and clypeus more 

 sparsely so ; temples shagreened, impunctate ; vertex not shagreened ; 

 middle of face and clypeus somewhat elevated; eyes large but not 

 conspicuously bulging; malar space two-thirds as long as basal wadth 

 of mandible, broader than cheek; lower end of occipital carina and
