Philonthus quediimis Horn. A male specimen of thi-. fine species 

 was taken here As the anterior marginal ])uncture of the thorax is 

 placed so unusually far behind the margm, and on a line with the three 

 discal ones, the discal punctures are apparently four. In this specimen 

 the singular bunch of bristles on the penultimate ventral segment consists 

 of about six, all difft^ring in length, and rising from a sm 11 median pit 

 resembling somewhat that seen in the male of some s])ecies of Derinestes. 

 The female was not tound, and to di tinguish it from those >j{ pal iatus, 

 van ru/u/us Fiuv . /uufor/nis, fuhiipes or occidentalism the number of the 

 thoracic punctures, ve.y sparsely and finely puni;tured elytra, and quedius 

 like aspect, would chiefly have to be depended on. Previous recorded 

 occurrence : Detroit, Mich.; Kansas. 



Xantholinus sanguinipemiis Lee. This species is very common and 

 abundant on Brigantine Beach and at .Atlantic City under trash from the 

 Bay. It is very easily confused with X ceph.ilus, which occurs with it 

 more sparingly and is similarly coloured ; the elytra are however of a 

 clearer red without any tendency to become infuscate as in the latter ; 

 the dorsal and lateral series ol punctures ol the thorax are more numer- 

 ous, coarser and constant, being exceedingly fine and some of them often 

 obsolete in the latter. The separation of the upper and lower marginal 

 lines of the thorax in the former species and their union anteriorly in the 

 latter is not a character of easy observation in the hurry of collecting. 

 Sanguinipennis will probably be fouiid to be a littoral species. Cephalus 

 occurs here, but always under bark, and I can see no difference between 

 these examples and such as are taken under rubbish on the coast. 



Canthon Icevis Drury. Since Mr. Blanchard's very clear statement of 

 the differences between this and chalcites Hald. (Tr. Am. Ent. Soc, XII., 

 164), it might be supposed these species would seldom be confused ; 

 the case is, however, different, probably owing to this exposition not being 

 generally in the hands of collectors, and the great similarity of the more 

 abundant colour forms of both species which renders tradition useless. 

 In northern collections Icevis is always correctly named. It is distributed 

 from Maine to Mexico and California ; in Canada, the New England and 

 Middle States its usual colour is coppery black or brown, but south and 

 west it varies from this to black, blue and green through all shades.
