tares, a yellowish, narrow, exterior, and subsutural [94] mar- 

 gin, and a common, arquated, somewhat undulated band behind 

 the middle, and a terminal one, obsolete or confounded with 

 the tip ; anterior feet and sternum testaceous ; posterior feet 

 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. 



[Belongs to Acilius, and was afterwards described as Colym- 

 hetes Maccullochii Kirby. — Leg.] 



4. D. T^NiOLis. — 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 dis- 

 tinct line each side before ; antennae, labrum, and nasus rufous, 

 the latter with an impressed line 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 subbasal 

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

 striae indistinct, that next the suture more obvious, and composed 

 of an interrupted series of minute punctures ; pectus and post- 

 pectus piceous-black ; feet rufo-piceous ; venter 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 pre- 

 viously applied to a different insect, although that insect does 

 not belong to this genus in a rigid arrangement. [95 ] 



QThis is a Colymhetes also found in South America ; itjwas pre- 

 viously described as D. calidus Fabr., and subsequently as Hyda- 

 tlcus meridionalis Mels. — Lec]
