108 TEETIAEY rvHYNOHOrilOEOUS COLEOrTERA. 



ACALYPTUS Sohonlien-. 



A g-enus containing only tlu-ef or fonr species, mostly European, but 

 one found in the East Indies; one of the European species occurs also in 

 North America, and a single fossil species has been found at Florissant.

PI. VI, Fig. 10. 



I I'efer to this genus one of the smallest of oiu' fossil Anthonomini from 

 its close general resemblance to A. niiijxiiiiiK ^^(•]llill]l., iigui'cd b^' Du \\\\, 

 with entire agreement in all the details of the structm-e which can be studied. 

 The body is stout and com])act, tajxn'ing considerably and rather raj)idlv 

 from the middh* of the abdomen forward. The head is subconicai, half as 

 high again as long, feeldy ))unctate and l)elow transversely, tinely, and 

 feebly striate; the eye circular, of aliout the diameter of the beak, with 

 about sixty large facets, each slightly less than OOl ;")""" in diameter; the 

 beak is long and slender, somewhat longer than head and thorax together, 

 gently arcuate and equal. The antenna? appeai- to be inserted and formed 

 precisely as in A. rufipcnnis, with the same proportional lengths, so far as 

 can be seen; the clul), however, is ol).scure. The thorax is well rounded, 

 tapering, about half as high again as long, very coarsel}' pimctate. The 

 elytra are well arched, much broader in the middle tlian elsewhere, and 

 rather coarsely ])unctato-striate, and the intersj)aces show feeble signs of 

 sj)arse and shallow punctuation.

This genus was fomided vijion a single sjjecies, which is still the onl\' 

 one known, and is found in the I'nited States east of the Kocky mountains. 

 It is interesting to find two fossil species both of which ()ccur oidy at 

 Florissant, and hence are jjrobaldx characteristic of the Lacustrine fauna.
