Chambers gave, however, an easily recognized description 

 (Can. Ent., v, p. 112, 1873) and a good figure of the vena- 

 tion (Jouru. Chin. Soc. Nat. Hist., vol. n, p. 201, 1880), and 

 the genus has long been well known among the few specialists 

 in the group. The genus is distinctly an American develop- 

 ment and in U. S. National Museum are several unpublished 

 species from Central America. Though I as yet have not seen 

 the present species, Cvane terpsichorella, from Central Amer- 

 ica, there is no doubt that it has been introduced into Hawaii 

 from there and that it eventually will turn up in collections 

 from the continent. 



THE GENUS LATHETICUS WATERHOUSE. 



[Coleoptera; Tenebrionidae.] 

 BY F. H. CHITTENDEN. 



A small tenebrionid beetle of the genus Lathcticus, prob- 

 ably of Oriental origin, has recently been introduced into the 

 United States, being thus far found in Texas, where it is very 

 evidently established, and in Michigan, where a similar estab- 

 lishment seems probable. The species in question is Lathet- 

 icus orvzcr Waterhouse. As the insect bids fair to become a 

 pest in time, and is therefore of interest to economic entomol- 

 ogy, the occasion is taken to furnish a description for the ben- 

 efit of American entomologists, together with an illustration, 

 and to point out the salient characters which separate the 

 species from a native form, L. prosopisCliittenden, which has 

 previously been recorded and described.

 General form of Tribolium ferrugineum F., but rather narrower, and 

 with the head relatively larger and broader and more square in general 

 outline. Forehead and middle of the epistoma gently convex: the 

 former not very thickly but very distinctly punctured ; the epistoma less 

 distinctly punctured, about twice as broad as long, obliquely (but not 

 much) narrowed anteriorly, declivous in front, impressed at the sides,
