as long, with the sides strongly rounded in front, and dilated In the 

 middle where it is broadest, and from thence almost straight in an 

 oblique line, or very slightly sinuate, to posterior angles which are right 

 angles; the elytra are considerably more finely punctured than tho 

 thorax ; in size this species comes between T. caricis and T. typhce. L. 

 2 mm. 



In stems of Typha, &c. ; rare ; Sheerness ; Birchington, near Margate ; Pegwell 

 Bay ; Sandwich ; Hythe ; New Forest ; Weston-super-Mare (where Mr. Crotch took 

 the two first specimens captured in Britain). 



CRYPTOPHAGUNA. 



This tribe contains a large number of species, but the arrangement 

 of the genera, which are few in number, is perhaps hardly established 

 with certainty. I have followed Thomson in adopting Micrambe and 

 Henoticus as distinct from Cryptophagus and Paramecosoma respectively ; 

 the species are as a rule more or less oblong, usually of a reddish-brown 

 or ferruginous colour, with the sides of the thorax, or at all events the 

 anterior angles, very often denticulate ; the upper surface is strongly 

 pubescent, and more or less setose ; our genera may be distinguished as 

 follows : 



I. Mesosternum deeply emarginate and foveate, re- 

 ceiving the process of the prosternum ; sides of thorax 



not denticulate ; size larger ANTHEBOPHAGUS, Lair. 



II. Mesosternum not foveate for the reception of the 

 prosternal process, which is shorter ; sides of thorax 



almost always denticulate ; size smaller. 



i. Tarsi with the penultimate joint equal to the pre- 

 ceding ; posterior tarsi of male 4-joiuted .... CBYJPTOPHAGTTS, Herbst. 



ii. Tarsi with the penultimate joint abruptly shorter 

 and narrower than those preceding. 



1. Thorax with the sides denticulate. 



A. All the tarsi 5-jointed in both sexes; anterior 



angles of thorax callosely reflexed ..... MICEAMBE, Thorns. 



B. Male with the posterior tarsi 4-jointed ; anterior 



angles of thorax not callosely reflexed .... HENOTICUS, Thorns.. 



2. Thorax with the sides not denticulate ; all the 



tarsi 5-jointed in both sexes ........ PABAMECOSOMA, Curt. 



ANTHEROPHAGUS, Latrcille. 



This genus contains about half-a-dozen species from Europe and 

 North America, and one from Northern Asia ; they resemble very large 

 Cryptophagi ; they appear to be usually associated with various species 

 of Bombi or humble-bees, but are often found in flowers and by sweep- 

 ing and beating herbage and undergrowth ; the names of our species 

 are somewhat misleading, A. pollens being by far the darkest coloured 

 of the three ; the posterior tarsi in the male are 4-jointed.
