54 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



L. foveata Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 257, 1897. 



Much like the brachypterous form of baswitta and like that 

 species marked with a fulvous band on the base of the tergum. It 

 may be distinguished by having the vertex, pronotum and scutellum 

 whitish-testaceous and the frontal carinae more conspicuously pale. 

 Reported from New York and may occur in Connecticut. 

 L. osborni Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 250, 1897. 



A pretty yellowish or fulvous species with conspicuous black 

 spots on the lateral angles of the male scutellum. It need not be 

 confounded with campestris which has the carinae obscure on the 

 rounded apex of the head. It is found throughout the eastern 

 states and should inhabit Connecticut. 

 L. lateralis Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 253, 1897. 



In this species the front is light brown with pale yellowish lines 

 and dots ; the dorsum is pale with a broad brown or blackish vitta 

 on either side. It may be distinguished from the next by its 

 having the median one-third of the tergum pale brown with a 

 slender whitish median line. It inhabits the northern states and 

 Canada.

 L. kilmani Van Duzee. 



Bull. Buff. Soc. Nat. Sci., 253, 1897. 



Near the preceding but differs in having a slightly broader front, 

 the pro- and mesonotum pale, and the broad dorsal vitta on the 

 tergum without a slender whitish median line. The male genital 

 characters are also very distinct, the stiles being narrow, pointed and 

 widely divergent in the present species while they are much wider 

 and more parallel in lateralis. In both species the brachypterous 

 elytra are brown and polished, with a pale marginal nervure. Like 

 lateralis this species inhabits the northern states and probably 

 Connecticut. 

 L. detecta Van Duzee. 



Bull. Buff. Soc. Nat. Sci., v, 248, 1897. 



This species has a broader front on which the white carinae are 

 conspicuously bordered with black, leaving a median fulvous line 

 in the axis of each compartment; the vertex and pronotum are 

 whitish with the fovae more or less blackish, and the scutellum is 

 fulvous. As in many of our Libumias the abdomen is black with 

 the base of the tergum marked with a fulvous vitta. It is dis- 

 tributed from New York to Florida and must occur in Connecticut.
