46 ADEPHAGA. \_IIaqmlus. 



K. puncticollis, Payk. Very like the preceding, but rather 

 shorter and broader in form, colour similar, thorax extremely variable in 

 shape, sometimes longer and more convex with sides strongly rounded 

 in front and much contracted behind, with posterior angles very promi- 

 nent (giving the insect somewhat the appearance of H. cordatus), at 

 other times shorter with the sides less rounded and more obliquely con- 

 tracted, with the posterior angles almost blunt ; the interstices of the 

 elytra are evidently less strongly punctured than in //. rupicola, although 

 more so than in //. cordatus, from which latter insect it may also be dis- 

 tinguished by the fact that tlie striae are always impunctate ; the female 

 has the apex of the last abdominal segment simple ; the base of the 

 thorax is sometimes bordered and sometimes presents no trace of a border, 

 so that M. Bedel's distinction, depending on this character, is unreliable. 

 L. 6-8 mm. 



Widely distributed and in many places common throughout England ; Scotland, 

 rare, Lowlands. Ireland, near Dublin and Belfast, and probably common. I once 

 took it on flower-heads that had gone to seed at Filey, Yorks. M. Bedel says that it 

 occurs on the umbels of Daiicus carota. 



K. rufibarbis, F. {hrevicoUis, Serv., crihellum, Steph.). Very 

 closely resembles the preceding ; the thorax however is, as a rule, much 

 shorter and broader than average specimens of H. ^^undieoUis, and has 

 the sides more rounded in front, and so, apparently, more strongly con- 

 tracted behind ; the interstices of the elytra are finely and not quite so 

 thickly pimctured as in that species, and the whole form is rather shorter 

 and broader. L. 6-8 mm. 



A widely distributed and sometimes abundant species in England ; Scotland, ap- 

 parently very rare ; Dr. Sharp has a specimen in his collection from Thoruhill, near 

 Dumfries ; not recorded from Ireland. I once took it very abundantly at Repton ; 

 in a space about a foot square I found between 100 and 200 examples near and upon 

 an old decayed fir- stump: these specimens did not differ much among themselves. 



K. parallelus, Dej. Very like H. puncticollis in form, but much 

 smaller and more parallel, with thorax about equal in length propor- 

 tionally to that of ordinary specimens of H. nifiharhis ; the posterior 

 angles of the thorax are right angles and not produced ; the elytra are 

 furnished with larger punctures or pores on the third, fifth, and seventh 

 interstices, and the general colour is darker than the allied species, 

 especially on the underside. L. 5-5| mm. 



Bare; first taken by H. Squire on the Sussex coast ; Rochester; Strood; Sheerness ; 

 Eastbourne ; Dover ; Sandown, Isle of Wight. 



M. Bedel (1. c. p. 172) considers this species to be synonymous with 

 H. puncticollis ; in some ways, however, it seems more closely related 

 to H. rujiharhis ; the fact is, that it is almost impossible to separate 

 these two latter species, and the distinctions that separate H. parallelus 

 from them are so small when they come to be tested, that it seems 

 almost impossible to retain it as a good species ; neither the small size.
