one-half wider tlian lon<f and distinctly shorter than the prothorax; sides evi- 

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

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

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

 men rapidly and very evenly tapering throughout, the erect black seta; not 

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



South Carolina,; Virginia (Xorfollv). 



The male above described has the tip of the sixth ventral 

 emarginate throughout tlie widtli, the notch broadly trianguhxr, 

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

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

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

 tion. Five specimens.

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

 verse and posteriori}' sinuate spot of red at the middle of the 

 base ; legs piceous-brown ; antenn.ne infuscate except toward base 

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

 dense. Length 2.5 mm.; 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 

 elytra and in fVict this sculpture, which is universal in the 

 American species of the preceding group, is frequently 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 epipleurse become vertical externally to- 

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

 along the inner marginal bead ; the}' do not quite attain the 

 elytral apex and the external angles of the elytra are rounded. 

 The basal angles of the prothorax are only feebly produced pos- 

 teriorly and are rounded.
