C. subtropicus, new species. 



Head black, labrum and epistoma pale, antennae pale at base, becoming 

 infuscate apically. Prothorax rufous with broad median black stripe ; elytra 

 deep blue; venter rufous, sides heavily maculate with black. Basal joint of 

 antennae (c^) subtriangular, not quite twice as long as wide, not excavate pos- 

 teriorly. Second joint a little wider than long, appendix short; third joints as 

 wide as those following. Prothorax polished, finely sparsely punctate. Elytra 

 quite strongly shining, rather densely but not very coarsely punctate, pubes- 

 cence as usual. Length 3^ mm. 



Jacksonville and Tampa. Florida, 2 S's; the former the type in 

 my own collection, the latter in the Horn collection. 



Mr. Schwarz writes me that there are similar specimens from 

 tropical Florida in the National Museum Collection. 



The specimens before me are a little smaller and even more shin- 

 ing, the punctuation of the elytra slightly coarser, and the basal an- 

 tennal joint a little more elongate than in vicarius, but otherwise they 

 are very close to the latter. The prothoracic stripe may or may not 

 be constant in subtropictis; it is probably never present in vicarius. 

 C. subaeneus, new species. 



Black, elytra faintly aeneous, labrum, basal joint of antennae and the upper 

 edge of the three following joints pale; prothorax rufous with broad black 

 median stripe; abdomen rufous, sides heavily maculate with black; legs black. 

 Head finely, rather sparsely punctate with a few coarser setigerous punctures ; 

 thorax finely remotely punctulate ; elytra closely not coarsely punctate. Antennae 

 (5) rather strongly serrate. Length 4 mm. (head deflexed). 



California. Contra Costa Co. and vicinity of Sacramento. De- 

 scribed from three $'s submitted by Dr. F. E. Blaisdell. 



The description of a species of Collops from the females only is 

 rarely justifiable but the total dissimilarity in color of the present 

 species makes it highly improbable that this can be a variety of any 

 previously described form occurring in the same region ; it is in any 

 event worthy of a varietal name.

A common species along the Atlantic Coast line from Massachu- 

 setts to Florida ; it occurs also on the Gulf Coast at least as far as 

 Mobile, Ala. The thoracic spot seems to be large and constantly 

 present in the northern specimens but is sometimes entirely absent
