282 SEEEICORNIA. 



Hab. Mexico, Merida in Yucatan 1 2 3 (Pilate, in coll. Janson; Salle), Temax in North 

 Yucatan (Gaumer). 



Var. The marginal band of white scales much narrower, the rest of the thorax and elytra, the base of the 

 latter excepted, clothed with minute greenish or cinereous scales. 



Hob. Mexico, Oaxaca (Salle), Tehuantepec (Sumichrast). 



There is a female specimen of the typical form of this species in the Janson collec- 

 tion and a pair in our own. The male, as noted by Candeze, has the apex of the 

 anterior tibiae and the apical joint of each tarsus fringed with long hairs. The upper 

 and under surfaces are clothed with elongate white scales, which form a broad marginal 

 stripe on the thorax and elytra ; the elytral interstices and a broad median vitta on the 

 thorax are sparsely clothed with minute brassy scales. Of the variety we have received 

 two examples, both females. We figure two specimens : a typical male from Yucatan, 

 and a female of the variety, from Tehuantepec.

With the types before me, I am unable to separate C. circumductus from C. angus- 

 tatus; the description of the latter was made from two males (one abraded), that of 

 C. circumductus from a single female. C. angustatus has the marginal bands of scales 

 on the thorax and elytra almost white, and the minute scales on the dorsum greyish, 

 the bands in C. circumductus being luteous and the minute scales olive-green. The 

 marginal bands on the thorax are rather narrow and extend obliquely from opposite the 

 -eyes to near the base, narrowing behind. The alternate elytral interstices are rather 

 broader and more raised in C. circumductus than in C. angustatus, but with the addi- 

 tional material before me too much importance must not be placed on this character. 

 We figure a female example, the type of C. circumductus, Cand.
