MUTILLA PSAMB1ATHE. 



2 . Black, with the upper part of the thorax red ; covered with 

 rigid, black and greyish hairs not closely set, third abdominal 

 segment with a transverse yellowish white band interrupted 

 longitudinally in the middle and not reaching the outer sides ; head 

 broader than long on the vertex, a little rounded laterally behind 

 the eyes which are large, roughly foveate and set with a short, not 

 thick slightly flavescent pubescence ; thorax as broad as the head 

 across the vertex, one-third longer than broad, nearly parallel but 

 for a slight sinuation at about the median part, sloping slightly from 

 the median part to the outer angle in front, perpendicular behind, 

 covered with large, elongate foveas, with the intervals raised, sharp 

 and wavy; abdomen pyriform, sub-sessile, first joint seemingly 

 impunctate, second covered with elongated punctures, with fine 

 raised intervals very closely set, the first segment has no pubescent 

 white band, but is beset principally at base with long erect greyish 

 hairs similar to those covering the legs, sides and under side of 

 the abdomen ; the second segment has no apical pubescent band, 

 but I am of opinion, judging by the punctuation of the apical part, 

 that the pubescence has been rubbed ; ventral carina laminate with 

 both ends truncate and a little sharp at tip ; tibiae with a double row 

 of spines, spurs white, pygidium very closely and finely punctured. 

 Length 9^ mm. 



$ . Black, with the whole thorax red, clothed with dense greyish 

 white hairs, apex of first and second abdominal segments fringed 

 with a white pubescence, third segment entirely clothed with the 

 same pubescence ; head more than twice broader than long on the 

 vertex, rounded a little in the posterior angles, eyes large, not 

 emarginate, deeply and closely pitted ; mesothorax with two longi- 

 tudinal median grooves, tegulae dark red, wings smoky from base to 

 apex, scutellum much raised, nearly round, fringed with closely set, 

 long greyish hairs, metathorax constricted at base, a little ampliated 

 behind with the posterior angles quite rounded, abruptly declivous, 

 more broadly foveate than the pro- and mesothorax ; first abdominal 

 segment moderately long, sharply dentate on each side at base, 

 gradually ampliated from there to the apex where it is as broad as the 

 base of the second segment which seems the continuation of it, and 

 is very little broader than long ; they are both closely punctured 

 with smooth intervals ; the ventral carina of the first segment is 

 laminiforrn and truncate at both ends, and slightly emarginate in 

 the middle ; the tibiae have one series of spines, and the spurs are 

 ivory-white. Length 12 mm.
