NORTH AMERICAN COLEOPTERA. ISH 



li. depicta n. sp. — Rufo-testaceous. leg;s entirely and antennse, except first 

 joint, black, elytra conjointly with three black stripes, the sutural bifurcate at the 

 base. Front sparsely punctate, at the sides and posteriorly slightly wrinkled- 

 Antennse nearly black, the basal joint rufo-testaceous. Thorax very little nar- 

 rowed behind, the margin rather wide, wider posteriorly, hind angles rectangular, 

 median line finely impressed, surface wrinkled and more rugulose near the side 

 margin. Elytra finely striate, striae obsoletely punctulate. intervals slightly eon- 

 vex, very finely alutaceous, general color pale yellow, a common black sutural 

 vitta which occupies the two inner intervals on each elytron, except a short dis- 

 tance at tip, and bifurcate about one-third from the base, on each elytron a vitta 

 beginning at the shoulder occupying the sixth and seventh intervals, becoming a 

 little broader near the apex. Legs and palpi entirely black. Length 2fi inch: 

 6.5 mm. (PI. 5. fig. fi.) 



This species belongs to the Aphelogenia group of Lebia, characterized 

 by the absence of mentum tooth. In its markings it resembles furcata, 

 but diifers from all our species in this series with wide thoracic margin 

 by its entirely black legs. 



Occurs in Montana.

'J he variety above indicated is that form in which nearly the entire 

 disc of the elytra, except a narrow side margin and apex, is black. I 

 have now specimens from Georgia which correspond in every particular 

 with the figure given by Chaudoir in his monograph (Bull. Mosc. 1871, 

 i, p. 40. PI. 3, fig. 127 t. The typical form of vittata has some resem- 

 blance to scnpnlaris, but there are many characters separating these. 

 L. conjvngens Lee. is really a variety of this species.

 In consequence of the correct determination of the preceding species 

 it becomes necessary to change the name of the present. It is also a 

 vittate species, but the common sutural vittata reaches the apex but does 

 not bifurcate at base ; the outer vitta is abbreviated at base and apex, 

 limited within by the fourth stria, extending over three intervals (5-6.-7), 

 but narrower toward the apex. 



Our species of the division Aphelogenia separate into two natural 

 series: (1) those with the thorax widely margined, and (2) those with a 

 very narrow margin. The first series contains the following species : 



Body beneath pale; head and thorax similar in color. 

 Elytra with the sutural vitta bifurcate at base. 



Femora in great part rufo-testaceous, sutural vitta bifurcating one-third from 



base ftircata Lee. 



Legs entirely black, sutural vitta bifurcating very near the base.
