460 GEOLOGICAL SURVEY OF THE TERKITOEIES. 



CE. inididata^ nov. sp. 



Middle foveola of the vertex somewhat elongate, elliptical, with a 

 median carina tbroagh it, and generally a depression at the frout at the 

 top of the frontal costa; lateral foveolie very shallow, small, triangu- 

 lar; the frontal costa expanding just above the ocellus and at the base, 

 sulcate in the middle portion. Pronotum contracted on the anterior 

 lobes, posterior lobe flat on the disk, rapidly expanding and punctured ; 

 median carina a dim line, slightly' raised on the front lobe ; apex right- 

 angled. Elytra and wings x>assing the abdomen about one-third their 

 length. AYings papilioform,* very broad, the exterior margin regularly 

 and beautifully undulated or waved ; anterior submarginal space almost 

 as broad as the elytra j nervules prominent, regularly and remarkably 

 parallel. 



Color, (dried after a short immersion in alcohol.) — Ash-brown. Head 

 and thorax sometimes mottled with darker brown or fuscous. Elytra 

 marked with dusky spots x)resenting a basal group, an irregular middle 

 band, those on the apical portion sporadic. AVings transparent, tinged 

 with yellow at the base, the outer halt' transparent or slightly fuligi- 

 nous: the inner margin of this i:)ortion generally forms an irregular 

 somewhat dusky stripe, parallel with the body when the wing is fully 

 expanded, not bending invrard at the hind margin ; sometimes the dusky 

 portion is indicated only by dark nervules and nerves, those of the 

 inner half always being yellowish-Yrhite. Posterior femora have two 

 black spots inside; the inferior channel black, or chiefly occupied by 

 two black spots ; i)OSterior tibine arc probably bluish when the insect is 

 living. 



Dimensions^ — 9 , length, 1.05 inches ; elytra, 1.12 inches ; posterior 

 femora, .51 inch; posterior tibiae, .17 inch. ^ nearly as large, with 

 similar proportions. 



1 found this species in Colorado and Wyoming east of the mountains. 

 I also find it among the collection made by Mr. Dodge in Colorado; 

 but as it is not among his collections made in Xebraska or Kansas, and 

 does not appear to have been in the collection made by Professor Uay- 

 den in Nebraska, it i)robably belongs nearer the mountains. 



CE. Haydenii, nov. sp. 



Head and thorax somewhat wrinkled. Vertex rather narrow ; cen- 

 tral foveola somewhat elongate; margins prominent and sharp; open 

 in front and continuous with the sulcus of the frontal costa; median 

 carina distinct ; frontal costa sulcate throughout its length, very nar- 

 row above the ocellus ; eyes prominent, sub-globose. Anteunse rather 

 longer than usual. Pronotum tricarinate; median carina distinct but 

 not prominent; lateral carinse distinct only on the i)OSterior lobe; third 

 transverse incision very distinct, nearly straight, cuts the median carina 

 about the middle ; the anterior lobes are covered with iiregular raised 

 lines, the posterior lobe with elongate tubercles; apex blunt, terminat- 

 ing in a right angle. Elytra and wings passing the abdomen, narrow. 

 Posterior femora slender. 



Color, (dried after immersion in alcohol.) — Dull clay-color, dotted with 

 brown or fuscous. A transverse fuscous stripe in front between the 

 eyes. A small fuscous spot about the middle of each side of the pro- 

 notum. Upper and lower margins of the elytra marked with small fus- 



* This term is used to distinguish the butteiliy form of the wiug from those 

 ■^ith regularly convex margius; iu this form there is a slight re-entering of the mar- 

 gin a little behind the frout; this applies to the general contour and uot to the smaller 

 scallops.
