70 STUDIES IN NORTH AMERICAN MEMBRACID.'E 



14. Telamona cucullata n. sp. PI. 2, fig. 10. 



Size and form of Telamona ampelopsidis but with the humeral angles 

 -more strongly produced and the dorsal crest forming a compressed oblique 

 hood which in the female leans well over the metopidium. Head short, 

 basal suture of the clypeus but poorly distinguished; its protracted apex 

 narrow, strongly incurved and inconspicuous beyond the line of the cheeks; 

 face pale closely and evenly inscribed and dotted with brown. Pronotum 

 rather slender; humeral angles strongly triangularly produced for about one 

 and one half times the length of the eye, their apex acute; metopidium low, 

 moderately convex, with a strong median carina. Dorsal crest beginning 

 at the line of the humeri, hardly half the length of the pronotum, produced 

 in a flattened tongue-shaped process which in the female is curved anterior- 

 ly and overhangs the metopidium, its superior and posterior edges forming 

 almost a single curve, scarcely broken at the posterior angle; posterior pro- 

 cess with about four indistinct longitudinal carinae. 



In the male the humeral angles are much shorter and less acute, being 

 produced hardly more than the length of the eye. Dorsal crest much less 

 produced anteriorly, its posterior angle more pronounced. 



Color pale testaceous brown in the dried specimens. Pronotum marked 

 much as in ampelopsidis, with an angled blackish line beginning at the 

 middle of the lateral margin and strongly dislocated about an oblong 

 blackish spot on either side of the anterior base of the crest; surface below 

 this line paler as is the base of the metopidium; there are some pale marks 

 on the middle of the crest and a linear vitta from the hind angle of the crest 

 nearly to the apex ; median carina of the metopidium carrying some black 

 points and a larger spot above; which may connect with the oblique lateral 

 black vittse; humeral angles chestnut brown and polished in the female, 

 darker and punctured in the male. In some examples the markings on the 

 pronotum are almost obsolete. Apex of the elytra with a brown cloud. 

 Length 9-10 mm. 



Described from one male and three female examples in the 

 Cornell University collection which were taken at Ithaca, N. Y. 

 This species has the produced humeri of Heliria and perhaps 

 should be placed there, but to do so would so alter the disting- 

 uishing- characters of the genus as to leave it almost identical 

 with Telamona. It might represent an extreme form of Heliria 

 in which the anterior foliole of the crest had become so abnor- 

 mally developed as to almost completely obliterate the posterior 

 foliole which is represented by the merest angle on the post- 

 erior declivity of the crest. The hood in this species imitates 

 in a way the porrect horn of Thclia but here it is strongly com- 

 pressed which will at once distinguish it. This insect has the
