Tdmatophilina.~\ CLAVICORNI.V. 309 



European genus has much the same facies as Cryptophagus, but Dr. 

 Horn remarks that the American genus Loberus " resembles, at first 

 sight, a small Halticine of the genus Crepidodera ; " the 5-jointed, but 

 apparently 4-jointed, tarsi, of which the fourth joint is very small and 

 obsolete, and the lobed second and third joints of the same will serve to 

 distinguish the tribe from its allies ; the Diphyllina are by some authors 

 associated with the tribe, but appear to be very distinct by reason of 

 their closed anterior coxal cavities and general sculpture-. 



TEXiBXATOPXXXZiUS, Heer, 



This genus contains about ten or a dozen species, eight of which are 

 European, and one or two are found in North America ; they resemble 

 Cryptophagus in general appearance, but are as a rule dark-coloured ; 

 they occur chiefly in stems of water plants, such as Sparganium, Typlia, 

 &c. 



I. Elytra testaceous or brownish-yellow with dark mark- 

 ings T. SPARQAKII, Ahr, 



II. Elytra unicolorous, usually black, occasionally 



pitchy. 



i. Thorax not or scarcely transverse ; sides sinuatf be- 

 fore base i posterior angles right angles. 



1. Sides of thorax gradually and not strongly rounded ; 



legs red ; size larger T. CAB1CIS, Ol. 



2. Sides of thorax strongly rounded in front, and 

 plainly narrowed and sinuate behind; femora 



usually black ;. size smaller . T. SCHoNHEBBi, Oyll. 



ii. Thorax distinctly transverse. 



1. Thorax about a third broader than long ; sides 



rounded to base ; posterior angles obtuse . . . ' T. TTPHJE, FalL 



2. Thorax twice as broad as long; sides almost 

 straight, or very slightly sinuate before basej 



posterior angles right angles T. BBEVICOLLIS, AuSc. 



T. sparg'anii, Ahr. Oblong, moderately convex, elothed with thick 

 yellowish pubescence ; head and thorax pitchy, the latter often reddish ; 

 elytra testaceous or brownish-testaceous, with the suture and scutellary 

 region, and a broad patch behind middle extending more or less along 

 the side margins to apex, black ; antennae testaceous, rather slender, with 

 a well-marked 3-jointed club, of which the central joint is the broadest ; 

 eyes rather prominent ; thorax about as long as broad, with sides rounded 

 and crenulate, sinuate just before posterior angles which are right angles, 

 closely but distinctly punctured ; elytra long, very gradually narrowed 

 to apex, finely punctured ; legs testaceous. L. 2-2| mm. 



In stems of Sparganium, Typha, &>.. ; rare ; Horning Fen (Sharp and Crotch) 

 Pegwell Bay, in the last week in May (Sharp and Saumlers) j Cobham, Surrey 

 (Stephens) ; Hythe ; Sandwich. In Dr. Sharp's collection there is a specimen from 

 Prgwell Bay which has the upper surface pitchy, with a broad testaceous baud ex- 

 tending along suture from neur base to apex.
