Tehnatoplnlijia.'] clavicornia. 309 



European genua has much the siune facics as Cnjpluphagu^, but Dr. 

 Horn remarks tliat the American genus Loherus *' reseml)k's, at lirst 

 sight, a small Ilalticine of the genus Crei>idudera ; " the 5-jointed, hut 

 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. 



TSZilAIATOPKIXiUS, Heer. 



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

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

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

 they occur chiefly in stems of water plants, such as Sj^coyanium, Typhit, 

 &c.

 ings T. SPARGANII, Ahr, 



II. Elytra nnicolorous, usually black, occasionally 

 pitchy. 

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

 fore base; posterior angles riglit angles. 



1. Sides of thorax gradually and not strongly rounded ; 



legs red ; size larger T. CARicis, Oi. 



2. Sides of thorax strongly rounded in front, and 

 plainly narrowed and sinuate behind; femora 



usually black ; size smaller T. SchoNHEBEI, Gi/fl, 



ii. Thorax distinctly transverse. 



1. Thorax about a third broader than long ; sides 



rounded to base ; posterior angles obtuse . . . T. TYPH^, Fall, 



2. Thorax twice as broad as long; sides almost 

 straight, or very slightly sinuate before base ; 



posterior angles right angles T. BEEVICOLLIS, Aubi. 



T. sparg-anii, Ahr. Oblong, moderately convex, clothed with tliick 

 yelloAvish 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, Tifpha, &•, ; rare ; Horning Fen (Sharp and Crotch) 

 Pegwell Bay, in the last week in IMay (Sliarp and Saunders) ; Cobham, Surrey 

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

 Pegwell Bay which has the upper surface pitchy, with a broad testaceous band ex- 

 tending along suture from near base to apex.
