CHyETOPHOROCERA, new genus. 



General external characters of Phorocera, but more bristly through- 

 out and all bristles heavy, long, and strongly developed; legs elongate. 



Female front at vertex about two-thirds eye-width or slightly 

 more, that of male about one-half eye-width. Male with two recli- 

 nate orbital bristles nearly in line with frontals; female with same 

 and two proclinate ones outside them. Face strongly receding, 

 front prominent in profile. Proboscis short and fleshy; palpi long, 

 curved, much thickened apically, with long bristles below on basal 

 part of thickening. Facialia ciliate usually to above lowest frontal 

 bristle with long strong bristles, a row of fine hairs outside them. 

 Parafrontals hairy. Eyes densely long-hairy. Facial plate broad, 

 the vibrissaB nearly on level with the slightly prominent oral margin. 

 Cheeks about two-fifths eye-height in both sexes. Face below as 

 wide as both eyes in male, wider in female. Second antenna! joint 

 not elongate, thnd joint about four times in female and five times 

 in male the length of second. Arista long, thickened on basal one- 

 third, microscopically short-pubescent basally. Irmer vertical bristle 

 strong, like the orbitals. 



Three sternopleural bristles; three postsutural bristles, very long. 

 Three lateral pairs of scutellar macrochsetse, the posterior pair 

 very long; one pair of long but weaker suberect apical decussate 

 bristles, and one discal pair of same strength. Scutellum with erect 

 moderately long bristly hairs. First abdominal segment with median 

 marginal pair of macrochsetee, second with median discal and mar- 

 ginal pairs, third with median discal pair and marginal row of 16 

 or 18 extending below, anal segment with marginal and discal row. 

 Hind tibiae with row of sparse bristles, about three of them longer, a 

 row of fine hairs among them. Female claws long and strong, those 

 of male much longer and stronger. Tibiae and femora moderately 

 bristly. Apical cell open well before wing tip, hind crossvein sinuate 

 and nearer to bend of fourth vein, usually no wrinkle or stump at 

 bend. 



Keproductive habit, leaf-oviposition; uterus with black micro- 

 type eggs whose choria show an arc-band pattern. 

 Type-species. — ChaetopJiorocera andina, new species.
