Molophilus auricomus is strikingly similar to the species that
we have been calling M. pubi,ltenncs(Osten Sacken) but theantennae are short and the male hypopygium is very distinct instructure. There is a possibility that the present speciesis thetrue pubil,enn,is,the types o{ which consist of females only.

lobes extensively dark trrown; scutellum a little paler than thescutum, dark brownish testaceous; postnotum dark, sparsely
pruinose. Pleura clear gray, indistinctly variegated with darker,

passing into brownish black; tarsi brownish black. Wings witha grayish tinge, the stigma and outer halves of cells C and Sc
darker; inconspicuous whitish hyaline spots, arranged as follows : Before the stigma in cells C and rs/ Rr; beyond thestigma in cells Rz and Rs; an obliterative area crossing the cord
and including parts of cells Rr, r.rf M2and M3; a circular spotlreyond midlength of cell M; basesof cells R, M, Cu,the AnaI

spot on either side of the median line at base, the color continued
slightly caudad to form broken sublateral stripes; on the sixthand remaining segments,the dark color increasesin amount toinclude the whole tergite; lateral and caudal margins of theintermediate tergites narrowly pale; basal sternites yellow, theouter segments black, with the caudal margins narrowly but
