erect hairs. Abdomen broad; discals on abdominal segments; outer 

 side of all tibiae in female with numerous long slender bristles, less 

 abundant in male. 



Genotype. — Gartocometes io, new species. 



CARTOCOMETES 10, new species 



Female. — Front wide, 0.45 of head width, the frontal stripe occu- 

 pying about one-half of this, rather light red in color; lower part 

 of head yellowish red, antennae of the same color ; frontal bristles six, 

 the uppermost not appreciably reclinate; the usual two orbital bris- 

 tles present; parafacials with numerous black hairs; back of head 

 with some small pale hairs on the lower part not very conspicuous; 

 palpi yellow. 



Thorax black on the disk, broadly reddish yellow on the sides 

 and pleurae, the latter, however, somewhat mottled with black be- 

 hind. Chaetotaxy : acrostichal 3, 3 (the hindmost rather large) ; 

 dorsocentral 2, 3; humeral 4; presutural 2; notopleural 2; supraalar 

 1; intraalar 4; 2 between supraalar and intraalar; postalar 2 (the 

 inner much larger); sternopleural 2, 1; pteropleural 1 small; scu- 

 tellum with 3 lateral pairs and a rather large decussate apical, discal 

 poorly developed, postscutellum well developed, black like the re- 

 mainder of the metanotum, the scutellum being reddish yellow. 

 Calypters white, the rim slightly infuscated on the inner side. 



Abdomen rather flat, hind edges of all the segments faintly reddish, 

 the surface somewhat variably mottled with light and dark pollen. 

 First segment rather long with a marginal pair, and in one specimen 

 a single discal ; second segment with a discal pair, and a marginal row 

 of about 14; third with two pairs of irregular discals and several 

 hair-like bristles scattered over the surface without regular order, 

 hind margin without a distinct row; fourth segment with irregular 

 ereet scattered hair-like bristles beginning at the front edge, no dis- 

 tinct marginal row. The sides of the abdominal segments have some 

 irregularly arranged long bristles. 



Legs, including tarsi, yellow, the femora with traces of infusca- 

 tion; all the tibiae with strikingly long hair-like bristles arranged 

 in several irregular rows ; tarsi rather strikingly short, pale to the tip. 



Wings subhyaline, the hind cross vein erect, joining fourth vein 

 hardly beyond the middle between small cross vein and bend, the 

 latter very broadly rounded ; the erect coarse hairs of the third vein 

 large, extending far beyond the cross vein in one specimen but only 

 to it in the other. 



Length, 5 mm. 



Male. — Front at vertex 0.43 of head width, more prominent than 

 in female; femora black in ground color except broadly on under- 

 side apically; claws and pulvilli small. Genitalia of unique struc-
