and Central American Malachiidae and Melyridae. 27 



under the MS. name " Collops saulcyi, Ch.," and said to be 

 from " Mexico." It has the antennae and head shaped 

 and coloured exactly as in a typical C. eximius (= nigriceps, 

 Say), (^, before me from E. Florida, this latter having the 

 legs and a large patch on the disc of the prothorax black. 

 The testaceous, tapering antennae of the male, with 

 unusually stout third joint, and the pecuhar sculpture of 

 the head, are the distinguishing characters of the present 

 species. Mr. Fall has sent me a female of C nigriceps 

 from New Jersey for comparison.

Depressed, black, the labrum, the base of the mandibles, the two 

 or three basal joints of the antennae (except on their lower face in 

 cj), the prothorax (except a small transverse, evanescent patch on 

 the disc, which is sometimes obsolete), abdomen, tibiae, and tarsi 

 rufo-testaceous, the head aeneous, the elytra blue or violaceous; 

 clothed with fine cinereous pubescence intermixed with long, erect, 

 black, bristly hairs. Head aeneous to the anterior margin in both 

 sexes, minutely, uniformly punctate; antennae ((^) with joint 1 

 widened from near the base, 2 with a long, slender, appendage, 3-5 

 transverse, equal, feebly serrate, 6-9 a little longer. Prothorax 

 shining, moderately transverse, sparsely, minutely punctate. 

 Elytra rather elongate, narrowed towards the base in both sexes, 

 rugulose, and densely, finely punctate. 



Length 3^-4, breadth l|-2 mm. ((J ?.) 



Hab. North America, Arizona, New Mexico, and S. W. 

 Texas; Mexico, Northern Sonora (Morrison). 



The above description is taken from seven specimens 

 sent by Morrison, one only of which is a male. This is a 

 rather narrow, depressed, feebly developed form, approach- 

 ing Anthocoinus. The black femora and clear rufo-testa- 

 ceous tibiae and tarsi, the relatively narrow prothorax, 

 and the finely punctured, posteriorly widened elytra, 

 readily distinguish C. parvus. Fall (loc. cit., p. 256) has 

 already called attention to the incorrect determination of 

 the Sonoran specimens.
