 being found beyond the Mississippi.

I have seen but a single specimen (Dr. LeConte's type), that agrees 

 in all respects with the description, and from it the figure here given 

 was made.

This species varies considerably in size, and somewhat in color of 

 markings ; a variety which has the space between the two posterior 

 fasciae brownish, pubescent furnished the type of Mr. Schwarz's hiero- 

 glyphica. It does not appear to be common. 



MORDELLA Linn. 



Species cuneiform; scutel triangular; anal style generally long and 

 slender ; hind tibia and tarsi without ridges except the short subapical 

 one of the former ; eyes finely granulated, antennae more or less serrate ; 

 last joint of maxillary palpi long, triangular and very obliquely truncate, 

 except in the % of M. oculata where it is broad and securiform with the 

 under surface clothed with erect hairs ; moderately thick and hollowed 

 out at the extremity. 



The species of this genus are usually rather rare ; two or three species 

 are common enough in the middle states, but the majority of them are 

 found in single specimens now and again. The species do not differ in 

 any important point from the foregoing or the two following genera, and 

 the mouth parts are well shown PI. I, figs. 34, 35. 



The species are found on flowers, rarely on old dead trees or beneath 

 loose bark.
