AMERICAN hemiptp:ra. 67 



elytra black, with the costa narrowly pale. This form includes the 

 varieties " b " and "c" of Say's Peidatoma elauda. The other form 

 is of a chestnut brown or piceous black, with the characteristic 

 markings ivory white, and the elytra white, with the narrow inner 

 margin and a wedge shaped median vitta black. This variety is 

 the typical elauda of Say, and also includes his variety "a." This 

 form bears quite a strong resemblance to the figure of Perilius vir- 

 gatus Stal on Plate 3, figure 22, of the Biologia. In the specimens 

 I have seen of the typical variety elauda Say, the base of the an- 

 teiinffi are blackish, not rufous as described by Say. 



Perilius cireuiiiciiictii$« Stal. 



This species seems to replace the preceding in the eastern United 

 States and Canada. In the west it extends from Manitoba to Miss- 

 ouri, and possibly southwardly to Mexico, as Dr. Uhler records its 

 occurrence in Panama and Trinidad, and Distant figures what he 

 takes to be a black variety from Mexico. The form of this species 

 is narrower and more convex above, and the pronotum is distinctly 

 longer than in bioeulatus. I have observed but little tendency to 

 vary in this species.

This insect l)ears quite a strong resemblance to Perilius conpuens 

 or a small specimen of bioeulatus Fabr., but it can be readily distin- 

 guished by tiie unarmed anterior femora, a character separating this 

 genus from Perilius. The color is deep blue- black, with the narrow 

 anterior, latei'oanterior margins and median longitudinal line, and 

 the broad latero-posterior submargiu of the pronotum, and a sub- 

 marginal vitta on the scutellum forming a perfect V, of a fulvous or 

 red. The narrow costal margin, the connexivum, and the body be- 

 neath are of the same fulvous red color, with the sutures of the 

 pleuree, a row of stigmatal spots, a narrow vitta on the base of the 

 venter, a large subapical square spot bifed before, and the anal seg- 

 ment blue-black. The antenna^ and legs are black, with the coxse 

 and femora beneath pale. Rostrum black, basal joint pale. The 

 head is slenderly edged with pale before, sometimes the larger ven 

 tral spot is broken into about six smaller ones, and in one individual 

 the red margin of the pronotum is continued around the base Dr. 

 Uhler records this species from New York, Maryland, South Caro- 

 lina, Georgia, Texas and New Mexico. It is included in the Gil-
