Five males and two females before me are doubtless referable to 

 D. appendiculafa Pic. These specimens, cJ ? , var}^ in the colour of 

 the head and prothorax (red to black), elytra (black or nigro-violaceous), 

 and femora and tibiae (black, with the basal halves or more of the femora, 

 except in one specimen, testaceous, or wholly testaceous), showing that 

 no reliance can be placed upon colour as a specific character. Miiklin's 

 description of D. coUaris (1875), S , from Santa Rita, applies to one of 

 the forms of the present species, except that the eyes in his insect are 

 stated to be separated by a narrow line above and beneath, and therefore 

 much more approximate than they are in D. appendiculafa. The type 

 of the latter, like that of D. collt/r/s, has a testaceous prothorax. The 

 elytral interstices are closely roughly punctate and transversely rugose in 

 the males, smootlier in the two females.

c5'. Moilerately elongnte, rather narrow, widened posteriorly, shining; 

 piceous or nigro-pir-eoii,«, the prolhorax usually with a greenish or aeneous 

 lustre, which sometimes extends to the elytra also, the latter often reddish 

 brown, the femora at the base or entirely testaceous ; thickly clothed, the 

 legs included, with lonu-, soft liairs. Head small, coarsely, rugosely punctnte, 

 the eves convex, modenxtel}' large, well separated, not reaching the base ; 

 autennae stout, very long, reaching to beyond the middle of the elytra, strongly 

 serrate from joint 3 onward, 11 equallmg 8-10 united, asperate on its inner f.ve. 

 Prothorax wider than the head, about as long as broad, feebly rounded at the 

 sides, slightl}' constricted before the rather prominent basal margin ; closely, 

 coarsely, irregularly jninctate, depressed in the centre at the base, and suh-ate 

 anteriorly. Elytra moderately h-ng, widening to the middle, and thei-e more 

 than twice the breadth of the prothorax, rounded at the apex, the marginal 

 (!aiina prominent ; closely crenato-striate, the punctures transverse, the inter- 

 stices Hat on the disc and convex at the apex, transversely rugose, and 

 irreguliirl)'^ uuiseriate punctate. Femora more or less sulcate beneath, the 

 intermediate pair with a compressed, membranous, suhtriangular lob« towards 

 the middle. Intermediate tibiae sinuate, undilated, hollowed towards the tip 

 externally, the anterior and posterior pairs (when seen extended) with a small, 

 narrow, curved, mend)rauous process at the extreme base, wdiich is received 

 into the femoral groove when the legs are drawn inward. 



Var. The prothorax rufo-testaceous, the legs in one specimen entirely 

 testaceous and the antennae ferruginous. 



2- Antennae shorter and more slender, very feebly serrate, joint 11 

 equalling 9 and 10 united ; eyes smaller and more distant ; prothorax and
