CYRTOLOBUS Goding. 



The species of this genus and their relationships are very imperfectly 

 understood. Several of the named forms besides those listed here have 

 been reported from ranges which would indicate that they may occur in our 

 region. There are on hand also four apparently undescribed species. 



Cyrtolohus (Xantholobus) nitidus Van Duzee was described from speci- 

 mens one of which was collected at Washington, D. C., in June, 1905. 

 (Studies, 1908, p. 97.) 



It should be noted that Cyrtolohus gloveri Goding (Catalogue, 1894, p. 

 434), said to be probably from Maryland, is a legitimately published species, 

 though no doubt an unidentifiable one. Van Duzee (Catalogue, 1917, p. 

 548) calls this a nomen nudum. What Goding refers to as Glover's ms. 

 Journ. Hom. is a published work, 12 copies of which were distributed to 

 leading libraries. A bibliographical citation is herewith given:

Homoptera Plate I, fig. 14 is Cyrtosia sp. afterward named gloveri by 

 Goding. Hoplophora gloveri Goding, another membracid name based on 

 this work, is not accounted for in the Van Duzee Catalogue. 



Key to the Species of Cyrtolohus. 



A. Pronotal crest not pinched-in laterally at any point, evenly curved, 



highest over humeral angles (subgenus Atymna). 



B. Pronotum more elevated, highest over humeri, curve of 



anterior end of dorsal crest as if made by rounding off a 



right angle, females green, males green or with dark 



markings castaneae. 



BB. Pronotum less elevated, highest distinctly behind humeri, 



curve of anterior end of dorsal crest much more obtuse. 



C. Face more smooth, cly pens larger and more polished; 



both sexes green inornata.
