as in Scudder's figure and the costal margin is evenly curved, instead 

 of being obtusely subangulate at about the end of the basal third. 

 There is at least a strong probability that the insect is specifically 



distinct. 



DETYOPSIS, new genus. 



Fulgoridae with broad maculated tegmina, the shape and structure 

 very nearly as in the oriental genus Detya Distant. Oblique veins 

 from subcosta to costa numerous (in the typical species about four 

 in 1 mm. of length) ; radius (in the typical species) about as far from 

 subcosta as the latter is from costa; radial sector forking considerably 

 before middle of wing; media freely branched, apparently much as 

 in Detija; subapical field (as in Detya) reticulated by rather numerous 

 cross-veins; veins reaching outer margm simple, in the type species 

 nearly four in 1 mm. From Varcia Stal, which occurs in the neo- 

 tropical region, this differs by the denser venation. 



Type. — Detyopsis scudderi, new species. 



DETYOPSIS SCUDDERI, new species. 



Plate 33, fig. 4. 



Length of tegmina, 11.7 mm.; width, 5.5 mm.; color pale fuscous, 

 with a broad wavy hyaline band across the middle of the disk, 

 broadest on costa, narrower and more or less G -shaped below, the 

 inner margin edged with darker brown; apical margin with two large 

 hyaline spots, an upper and a lower, with an obscure small third one 

 between. The median band corresponds in position Avith that of 

 Scamandra diana Distant, from the Malay region. There is some 

 resemblance to the much smaller ApJiana rotundipennis Scudder, but 

 the costa is much less arched than in that species.

DETYOPSIS PACKARDI, new species. 



Plate 33, fig. 3. 



Length of tegmina, 10 mm.; width, 4.2 mm.; similar to D. scud- 

 deri, but tegmina narrower, with the region between costa and sub- 

 costa only half as broad; median hyalme band very obhque and equally 

 broad throughout as far as the sutural vein, its upper part bent nearly 

 at aright angle; apical region with three marginal hyaline spots, not 

 very large or conspicuous, one on costa, one on outer margin, and one 

 near the anal angle, these corresponding with the spots in Detya 

 fusconehulosa Distant, but the third spot (second on outer margin) of 

 Detya is absent.

 Named after Dr. A. S. Packard, who collected many fossil insects in 

 the Green River shales.
