basal half than the other species, but there is lut sign ot spinous hairs, and 

 the tegniina are more pointed at tip.

Florissant. One specimen, No. 30.

 PI. 21, Figs. 4, 5, 11, 14. 



This seems to be an abundant species, if all the specimens I have re- 

 ferred to it belong here, but not a single one is well })i"eserved, and if cor- 

 rectly placed it must have been an exceptionally delicate insect, 'llie most 

 that can be said of it in distinction from the otlier species is that the tegmina 

 are slender, fully three times as long as broad, with tolerably distinct veins 

 throughout, the costal border slightly curved at extreme base and gradually 

 falling to join the apical margin on the apical fourth of the wing, the apex 

 slightly produced and perfectly symmetrical ; they show no signs of thick- 

 ening of the costal margin and were evidently without markings. The hind 

 tibiae appear to be longer than in the other species. 



Length of body, 7.25""" ; of tegmina,5"'"' ; lireadth of thorax, 2"""'. 



Florissant. About fifty specimens, of which the best are Nos. 1970, 

 5400, 11103, 12447, 13337, 14178. 



4. LiTHECPHORA MURATA. 

 PI. 21, Figs. 3, 8. 



This species is larger than the preceding, which it much resembles, dif- 

 fering from it in imitating to a certain extent the markings characteristic of 

 Palecphonie. The tegmina are slender, nearly three and a half times longer 

 than broad, with the costal border strongly shouldered at base and scarcely 

 declining at tip, the apex broadly and symmetrioalh' rounded and in no 

 way produced: the venjition is very feeble and the markings, dark on a 

 light ground, consist of a basal costal striga and two cloudy transverse 

 streaks, only on the costa at all distinct and there obscure, dividing the 

 wing into nearly equal thirds. All the specimens are poor. 



Length of body, S""'" ; of tegmina, 6.5™"" ; breadth of thorax, 2.9""". 



Floris.sant. Three specimens, Nos. 912, 11007, 12776.
