intermediate between the other two. It has elytra Kke the fortna 

 typica and the rest of the vestiture similar to var. b. 



Ischiodontus ichthydius Cand. is quite common in Mexico and 

 Central America, but this is the first record I have seen of the

 interesting, inasmuch as this species is unknown in literature, ex- 

 cept for the two cotypes mentioned by Champion^ from Guatemala.

Horistonotus elegans (Sol.) Cand. is recorded only from Chilki

 front, anterior angles of the prothorax, anterior angles and tip of elytra, obscurely 

 reddish brown, under parts castaneous, legs dusky yellow, antennse yellowish fer- 

 ruginous. Front strongly umbilicate punctate, pronotum densely on sides and 

 sparsely on disc umbilicate punctate (PI. V, Fig. lb). Posterior angles very short 

 and almost rectangular, not carinate. Deep incision on posterio margin of prono-

 punctures elongate near the sutures (PI. V, Fig. Id) becoming round as they 

 approach the side margins. Prosternum with but few scattered simple punctures 

 almost without punctuation. Scutellum pentagonal. Posterior coxal plates (PI. 

 V, Fig. Ic) very abruptly widened near middle but without median tooth, outwardly 

 incomplete. Elytra punctate striate, strial punctures elongate and about as dis-
