262 THE CANADIAN ENTOMOLOGIST. 



Species of the Atlantic 7-egions. 



The following species are described in every instance from the male 

 alone : 



Batrisodes declivis, n. sp. — Form, coloration and sculpture nearly as 

 mfossicauda, the abdomen having the same gradually pointed form; head 

 similarly gradually and evenly declivous from the interfoveal convexity to 

 the clypeal apex, without break in continuity, and coarsely, densely 

 punctato-scabrous, the small and fine ambient sulcus similarly feebly 

 indicated, the antennal prominences feeble ; clypeal margin evenly and 

 broadly arcuato-truncate throughout the width ; antennae similar, except 

 that the penultimate joint is subglobular and less transverse, and having 

 on its under surface a large deep circular pit in basal two-thirds, the 

 eleventh joint slightly narrower than the tenth, elongate, gradually 

 pointed ; prothorax obtrapezoidal, slightly elongate, decidedly narrower 

 than the head ; elytra similar, having finely denticulate humeri ; abdomen 

 distinctly narrower than the elytra but equally long ; pygidium similarly 

 excavated across its lower portion but more obtuse from a dorsal view- 

 point ; abdomen with a small and feeble apical indentation, which is 

 shallower posteriorly. Length, 2.1 mm.; width, 0.78 mm. Iowa (Iowa 

 City), H. F. Wickham. 



'Rt^tmhXtsfossicauda^ Csy., but differs in antennal structure and in 

 in its much wider head, with larger and more prominent eyes ; the head 

 'mfossicauda is not wider than the prothorax. 



Mr. Raffray -p^d^cts fossicauda, on page 159, as a doubtful synonym 

 of bistriatus, Lee. It is rather difficult to understand the necessity for 

 this surmise, in the absence of accurate data, but to set the matter right, I 

 may say that there are numerous important points of difference between 

 these two species ; the front, for example, is more declivous anteriorly than 

 superiorly, and not evenly declivous from the occiput to the clypeal 

 margin, as it is in fossicauda and declivis, and the peculiar transverse 

 pygidial excavation of those two species does not exist. 



Batrisodes appalachiamis^ n. sp. — Form as in punctifrons^ darker in 

 colour, nearly black, the prothorax rather more inflated at the sides and 

 fully as wide as the head, if not somewhat wider, the latter similar except 

 that the flat declivous front is less uniformly punctate, more sparsely so 

 medially than laterally, and bearing, not short and very coarse bristles as 

 m pu7ictifrons^ but fine, short and inconspicuous hairs, the apex narrower
