884 ZOOLOGY— INSECTS. 



foveolate, being simply flat triangular spaces. Frontal costa rather narrow; 

 sides parallel, distinctly channeled, scarcely or not expanding at the ocellus; 

 ocelli immediately below the external angle of the tempora and close against 

 the front margin of the eyes at the middle. 



Pronotum rather narrow ; median carina distinct, though but slightly 

 raised on the posterior lobe, more prominent on the anterior lobes, severed 

 twice by the transverse incisions. The posterior sulcus about or slightly in 

 front of the middle ; the middle lobe shorter than the anterior one ; lateral 

 carina? subdistinct ; anterior margin distinctly obtuse-angled, posterior mar- 

 gin about a right angle or very slightly acute. Elytra and wings passing 

 the abdomen fully one-third their length. The wings are broad and some- 

 what papilioniform, reminding us very much of CE. undulata, to which, in 

 fact, this species appears in several respects to be closely allied. 



Color (alcoholic). — Dull ashen-brown throughout, sprinkled with fus- 

 cous dots. The elytra are somewhat darker brown on the basal third, 

 which is the extent of the densely veined portion ; the other two-thirds 

 being less densely veined, semi-transparent, and sparsely sprinkled with fus- 

 cous dots. Wings transparent ; the veins and veinlets of the apical half 

 dark ; the veins prominent and strong ; it is possible these were of a bluish 

 tint when living, yet they may have been tinged with greenish-yellow. 



Length of body, 0.85 inch; elytra, 1.00 inch; posterior femora, 0.50 

 inch. New Mexico. 



The female has a very distinct longitudinal carina through the central 

 foveola of the vertex. The interior of the posterior femora marked with 

 black or dark-brown, and slightly sprinkled externallv. 



Length to tip of elytra, 1.25 inches. 



It is possible this belongs to CE. undulata, but if so the venation of the 

 wings is very different, the undulata having the transverse veinlets very reg- 

 ularly scalariform and close, while in this there is no such marked arrange- 

 ment. This single character I think is entirely sufficient to show the two 

 are quite distinct. The two species are true CEdipodce as the genus is now 



restricted.
