MORGAN HEBARD 35 



Generic Description. — Size and form medium for the group, 

 structure very delicate. Interocular space moderately wide. 

 Occiput rounding evenly into inter-ocular-ocellar area, which is 

 not strikingly flattened; face not strongly convex with lateral 

 margins rather strongly convergent to clypeal suture. Distal 

 joint of maxillary palpus large, but not as long as preceding joint. 

 Pronotal surface weakly convex. Tegmina and wings fully devel- 

 oped in both sexes; tegminal discoidal sectors decidedly oblique. 

 Wings with costal veins heavily clubbed distad, intercalated trian- 

 gle not large but moderately conspicuous. Dorsal surface of male 

 abdomen with sixth segment specialized; concealed genitalia com- 

 plex; subgenital plate asymmetrical. 



Ventro-cephalic margin of cephalic femora armed with a series 

 of well spaced long heavy spines, succeeded by a series of closely 

 set chaetiform spines (type B), terminating in three heavy spines, 

 very elongate in increasing ratio distad. Ventro-caudal margin 

 of cephalic femora armed in distal third with well spaced (three 

 and one distal) heavy spines. Other v^entral femoral margins 

 well supplied with heavy elongate spines. Four proximal tarsal 

 joints supplied ventro-distad with small pulvilli, these slightly 

 produced caudad but with apices rounded, not acute. Tarsal 

 claws unspecialized. Moderately well developed arolia present. 

 Eudromiella bicolorata new species (Plate II, figures i6 to 20.) 



The pale vertex and darkened face, strikingly bilineate prono- 

 tum, bicolored tegmina and wings with area of enlarged portion of 

 costal veins whitish, are distinctive features of coloration in this 

 small roach.

In addition to the generic features already given, we would note the following. 

 Interocular space about three-quarters as wide as that between antennal sockets. 

 Ocellar spots distinct, these areas showing no delimiting contour. Third joint of 

 maxillary palpi very slightly longer than fourth, fifth (distal) joint enlarged, very 

 slightly shorter than (in the series, to as long as) the fourth. Tegmina with nu- 

 merous discoidal sectors (in the series nine to fourteen, the latter number due to 

 distal branching). Wings with (five to seven) branches of the ulnar \-ein, inter- 

 calated triangle small but distinct, its width appreciabl>- less than its depth. Sixth 

 dorsal abdominal segment with a decided median concavity, haxing on the caudal 

 face a minute but strongly developed semicircular ridge, cephalad of which is a
