distinct facies, and the under-side is differently coloured ; those from 

 Florida being luteous brown beneath, while the Arizona examples are 

 bright rufous. 



Hypophhvus, n. s. — Three examples were beaten from Melothria 

 vines, but whether they bred in them or in the cedar posts which sup- 

 ported them is not known, and the matter is mentioned to call the atten- 

 tion of future collectors. This species is narrower than giaber, which 

 occurs also ; the elytra are finely but distinctly punctured in close rows. 



Talanus {Dignamptus) langurinus and stenochitms. — These two names 

 represent the extremes of one species (Horn). Dr. Leconte having only 

 one example of the latter and two or three of the former before him, and 

 knowing nothing of the graduating intermediates, or the history of the 

 species, found enough of differential points for two species. It was 

 beaten abundantly from the dead vines oi Melothria, in which it probably 

 breeds, though I did not find larva nor pupa. It varies in length from 

 .15 to .40 inch, which is no greater difference than is found in some 

 other species, as Spalacopris filiim, Catogenus riifus, etc. The colour of 

 the types is represented as " black with a bluish gloss," and "black with 

 a slight metallic gloss." All the examples taken by me, and others in my 

 collection from Bay Biscayne and from Louisiana, are from light to dark 

 castaneous. It requires a little faith to see any great resemblance to 

 a Lajignria. Dr. Horn names the species as a whole langurinus. 



Cryptorhynchus mi7iutissi)nus, var. — This species was beaten in 

 some abundance from both living and dead vines of Melothria, in which 

 it probably breeds. The typical examples of this species in my collection 

 from Louisiana, and also one taken at Lake Worth on another plant, have 

 the thorax and elytra beautifully ornamented ; but this variety is sordid 

 brown, with the apical third of the elytra luteous. Some one hereafter 

 may possibly describe it as a new species. 



Trichobaris insolita, Casey. This species was taken abundantly in 

 a patch of a species of ground cherry (Fhysalis), April loth. None 

 occurred afterwards nor elsewhere, though Fhysalis is abundant. It 

 probably breeds in the stems of this plant, like trinotata does in the 

 potato. I found a coleopterous larva in one of the plants, but no pupa, 

 and so can not write with certainty. 



Cylas formicarius. — Three examples were taken on the ocean 

 beach from a rough, prostrate compositous plant, growing in mats on the 

 sand. The species is said to depredate on the sweet potato, but in this
