344 Mr. G. 0. Champion on various 



notch at the apex. Tegnieu with two long, widely separated, 

 straight lateral lobes, which are fringed with long hairs at 

 the tip. Penis-sheath stout, acuminate and slightly up- 

 turned at the apex. 



$ . Ventral segment shorter than 5, simple. 



Hob. Colombia ; Venezuela. 



A common insect in the countries quoted. The typical 

 form has a transverse, angulate red patch on the outer part of 

 the elytra before the middle, sometimes (var. fenestra tus, 

 Pic, 1. c.) extending forward along the outer margin and up 

 the middle of the disc to the base. Examples also occur 

 with a small red spot at the base and one or two others beyond 

 the middle. The <J -characters are described from three 

 specimens dissected many years ago by Dr. Sharp.

£ . Ventral segment 5 broadly arcuato-emarginate, 6 with 

 an oblong excavation in the centre at the apex, and the apex 

 itself deeply emarginate. Tegmen with short, broad lateral 

 lobes, the apices of which are obliquely truncate and thickly 

 set with long hairs. Penis-sheath stout, gradually narrowed 

 and slightly curved at the tip. 



• Hob. ? Colombia (Mus. Brit.); Peru, Jaen de Bra- 

 camorras {Humboldt and Bo upland). 



Two males in the Museum labelled " Colombia " and ac- 

 quired in 1844, agree with Latreille's fi gure of D. rubripennis 

 and Erichson\s subsequent description of the same species. The 

 .elytia have the reddish portion of the surface more extended 

 than in A. bonplandi, leaving a broad, posteriorly angulate 

 space at the base (enclosing an oval or oblong reddish patch), 

 a small spot on the disc towards the apex, and the sutural 

 and apical margins black. The very different <$ -armature 

 shows that the two insects are distinct.
