one-half wider tliau long and distinctly shorter than the prothorax ; sides evi- 

 dently convergent from the base but only very feebly arcuate, the angulate 

 emargination of the ajjex exceedingly feeble; disk convex, evenly and not 

 very finely imbricate, the imbrications pronounced and not reticulate. Abdo- 

 men rapidly and very evenly tapering throughout, the erect ])lack setse not 

 evident toward base. Length 1.4-1.6 mm. ; width 1.0-1.2 mm. 



South Cfirolina, ; Virginia (Norfolk). 



The male above described has the tip of the sixth ventral 

 emarginate throughout the width, the notch broadly triangular, 

 and about three times as wide as deep, with the sides feeblj- arcu- 

 ate and the angle narrowly rounded ; the fifth ventral is com- 

 pletel3' unmodified at apex and without trace of median sinua- 

 tion. Five specimens.

Oval, convex, shining, black, each elytron with a large trans- 

 verse and posteriorly sinuate spot of red at the middle of the 

 base; legs piceous-brown ; antennae infuscate except toward base 

 and at the apex ; pubescence very short, dark in color, rather 

 dense. Length 2.5 ram.; width 1.6 mm. 



Europe, eastward through Asia and along the western coast of 

 North America to the mountains of California. This species 

 is remarkable in having no trace of imbricate sculpture on the 

 elj'tra and in fact this sculpture, which is universal in the 

 American species of the preceding group, is frequentl}- sub- 

 obsolete in this section of the genus ; in the present species the 

 surface is finely punctulate and minutely and transversely stri- 

 gilato-reticulate. The epipleura? become vertical externally to- 

 ward base and are glabrous, with the exception of a few hairs 

 along the inner marginal bead ; they do not quite attain the 

 el3'tral apex and the external angles of the elj^tra are rounded. 

 The basal angles of the prothorax ai-e only feebly produced pos- 

 teriorly and are rounded.
