Abdomen opaque brown, first segment as long as, or longer than, 

 second, with a narrow pale line along posterior borders of all segments. 

 Slightly yellowish gray pollinose on dorsolateral bases of all segments 

 when viewed from rear. Macrochaetae weak, no median discal or 

 marginal macrochaetae on ist or 2nd segments, usually a weak apical 

 pair on 3rd segment, 4th segment with discal but no marginals. 



Wings tinged with brown, long, somewhat pointed, apical cell open 

 in margin and entering costa close to extreme wing tip. Squamae con- 

 colorous with wings. 



Coxae yellowish, femora brown, knees yellow; tibiae and tarsi yel- 

 lowish, densely clothed with short black hairs. Claws of front feet 

 as long as last tarsal joint. 



This sex is easily distinguishable from the male of Eutrixa by its 

 much narrower front and face. 



Female: Front at narrowest part about one-half eye width. Ovi- 

 positor exposed, horny, slightly curved, clear brownish and doubled 

 forward beneath abdomen. Otherwise this sex closely resembles the 

 male. 



Type. A female deposited in U. S. National Museum, 

 Washington, D. C. Four specimens, two of each sex, reared 

 from adult beetles of the genus Lachnosterna (sp?) collected 

 at Anasco, Porto Rico, May 14-16, by Mr. T. H. Jones, in 

 honor of whom the species is named. 



Chaetophleps crassinervis n. sp. (PI. Ill, figs, h, i.) 



Minute, opaque grayish, wings hyaline. Facies resembling Plectops 

 tnelissipodes Coq. Front opaque cinereous, slightly wider than either 

 eye, sides parallel, parafacials almost linear, facial depression as wide 

 as either eye, face entirely cinereous. Vertical bristles stout, almost 

 as long as eye-height, curving backward. Fronto-orbitals three, the 

 lowest stronger, upper two close together. Frontals in a single row 

 descending below the base of second antennal joint. Several proclinate 

 coarse black hairs between frontals and margin of eye opposite base 

 of antennae. Lower half of face bare. Antennae entirely black, mi- 

 nutely pubescent, descending to or slightly below oral margin, second 

 joint short, third joint largely developed, straight on front edge, pos- 

 terior edge convex, at widest part fully one-half as wide as either 

 eye. Penultimate joint of arista scarcely longer than broad, arista 

 pubescent on its basal half and incrassated nearly to the middle. Vi- 

 brissae inserted on the oral margin, stout, very long and cruciate, 

 three or four bristly hairs above them on vibrissal ridges, remainder 

 of ridges bare. Lower part of occiput produced backward somewhat 

 as in Thryptocera. Proboscis short, yellow, palpi slender, black.
