94 DESCRIPTION OF INSECTS 



tural margin, and a common, arquated, somewhat undu- 

 lated band behind the middle, and a terminal one, obso- 

 lete or confounded with the tip. 



Anterior /ee^ and s^e/'/zz/w testaceous ; posterior /(^e^piceous; 

 thighs black; venter, third, fourth, and fifth segments each 

 with a large, rufous, lateral spot. 

 The grooves of the elytra in the female of this species are 



obsolete and abbreviated, and not more distinct than those 



of the male. 



4. D. HcenioUs blackish ; thorax margined each side with 

 rufous ; elytra covered with confluent black points, three 

 acute, pale rufous, longitudinal lines on each elytron. 



Length rather more than half an inch. 



D. pictus. Melsh. Catal. 



Body oblong-oval, not wider behind, black varied with rufous, 



beneath piceous-black. 

 Head with a double, impressed, very distinct line each side 

 before ; antennae, labrum, and nasus rufous, the latter 

 with an impressed hne each side. 

 Thorax with a slightly punctured, transverse line before, and 



an obscure rufous margin. 

 Elytra rufo-testaceous, but rendered black by small, dense, 

 confluent punctures, which are entirely confluent near the 

 suture, an immaculate outer margin, and undulated sub- 

 basal line, three acute pale rufous lines on each elytron, 

 punctured strise indistinct, that next the suture more ob- 

 vious and composed of an interrupted series of minute 

 punctures. 

 Pectus and postpectus piceous-black ; feet rufo-piceous ; ven- 

 ter piceous-black, segments piceous at tip. 

 I have seen but one sex of this species, a female, which 

 was sent to me by Dr. J. F. Melsheimer, under the name 

 which I have adopted ; that of pictus above quoted having 

 been previously applied to a diff*erent insect, althou2;h that 

 insect does not belong to this genus in a rigid arrangement.
