258 Mr. T. D. A. Cockerell — Descriptions and 



otherwise bare apical part of ihe segments, the black zone 

 very narrow on the first segment, broad on the three following ; 

 hind margins of segments not hyaline, except the first very 

 narrowly ; eyes dark olive ; facial quadrangle approximately 

 square, but broader above than below ; mesothorax shining 

 and strongly punctured ; tegulas fermginous, with ferruginous 

 hair. Wings dusky, stigma and nervures ferruginous. Hair 

 on inner side of tarsi orange. 



In the tables in Trans. Amer. Ent. Soc. 1906, this runs to 

 group F (p. SO), and having the fifth abdominal segment 

 with white hair from side to side, falls in the vicinity of 

 Janieri and aurfgenia, except for the larger size. It is easily 

 separated from lanieri by the pale median hai -band on 

 second abdon inal segment and lack of metallic colours on 

 abdomen. From aurigenia it is easily known by the larger 

 size and dusky wings. It is very close to M. hortivagans, 

 Ckll., differing in the colour of the abdominal bands and of 

 the hair on the apical part of the abdomen. Compared with 

 M. .vanthopteralis, Ckll., the mesothorax is much more 

 evidently punctured, and there are many differences in the 

 pubescence. M. masuca, Ckll., is also closely allied ; the 

 band on middle of second abdominal segment is quite straight 

 in masuca, which is not the case in cilliciatn.

The name colliciata was proposed by someone unknown to 

 me, and appears on the label of one of the specimens. Upon 

 comparison with female M. tepaneca, GvesFon, this might well 

 be supposed to be its male ; the male of tepaneca is known, 

 however, and is easily separable.

Hobust, black ; light hair very pale yellowish; black hair 

 on clypeus, labium, base ot mandibles, extreme sides of face, 

 top of head, mesothorax except anterior fourth, scutellum, 

 ventral surface of thorax and bases of legs, underside of 

 abdomen, and whole of filth and sixth segments dorsally ; 

 the hair of the first two pairs of legs is mainly dark, though 

 not actually black, but all the basitarsi have the hair on inner 

 side ferruginous ; the hair at apex of hind femora is dark, but 

 ihe loose strongly plumose scopa of hind tibiae and tarsi is 

 light ferruginous; abdomen with three light (dull yellowish- 

 grey) hair-bands, that on second segment failing in the 

 middle; facial quadrangle much broader than long ; antennas
