A RFVISION OF THE BRITTSH SPKCIRS OF BAOOUS. SCHON. 156 



liiitosus, breviti and claudkaus. It can be separated from the first two 

 by the feeble constriction of its thorax, and from the latter by its 

 long sub-equal tarsal joints and more or less punctured eljtral striae. 

 In the fresh state the two punctiform spots on the third interstice are 

 very conspicuous. The apical spur of the tarsi is very strongly 

 developed, especially in the males. The elytral strire are, in rare cases,. 

 very strongly punctured causing confusion with liinosiis, the different 

 form of the thorax is, however, decisive. Brisout admits that the 

 subcarinatiis, Gyll., of his monograph is very possibly the true frit of 

 Herbst, according to a remark of Dr. Schaam's upon Germar's 

 collection. Very local, but not uncommon — Sheerness (Champion, 

 Walker) ; Camber, in sedge refuse ; Rye, Iden (Bennett).

 'An.— Frit, Bris, 503.— Cox, ii., 191.— Fowler (in part), v., 290, and of 

 old Brit, collections. Adspersm, Forst (small form). — A very variable 

 >^pecies both in size and markings. Its nearest ally is frit from 

 which it can be separated by the characters given in the table. It is 

 usually smaller, and the spots on the elytra more transverse and 

 irregular, but it is sometimes unicolorous. The posterior tibijB are 

 shorter and less cylindrical than those of frit, and much less roundly 

 curved at apex. Rather generally distributed — Southsea (Moncreatf) ; 

 Potter-Heigham, Norfolk, in dykes (0. E. Janson) ; Camber, Iden, in 

 numbers (Bennett) ; Halton, Bucks ; Tring (Elliman) ; Slapton, 

 Devon (Keys). A specimen in Dr. Power's coll. labelled petro must be 

 referred to this species. 



B. LUTULOsus, Gyll., iv., 568. — Bris, 506. — Bedel, vi., 106 and 

 278. — Cox, ii., 191. — Fowler, v., 290. — This species and dii/h/ptus are 

 very distinct by reason of their short tarsi, forming a little group by 

 themselves. They may be distinguished from each other by the 

 characters in the table. As far as I have seen, this is our smallest 

 species. Rare, Guestling, Sussex, one swept in a dry lane (Bennett) ; 

 Southsea (Moncrealf) ; Woking, Horsell (Dr. Power). 



B. DiGLYPTus, Boh., Schon., viii., 2, p. 82. — Bris, 505. — Bedel, vi., 

 106 and 278. — Fowler, v., 291. — The more even elytral interstices and 

 usually larger size will distinguish this from the last species. One of 

 our rarest species. I have only seen the two specimens taken by Mr. 

 Claude Morley on the banks of the Gipping, near Ipswich, one of 

 which he very kindly gave to me. One was taken by sweeping at 

 dusk, the other in flood refuse {Etit. Mo. Ma;/., xxxiii., 44). These and 

 the two specimens taken at Burton-on-Trent (see Fowler) are, I believe, 

 the only known British examples. M. Bedel tells me that it is 

 extremely rare in France. 



B. GLAERiRosTRis, Hcthst, vi., 254. — Bedel, vi., 106 and 279. — 

 Fowler, v. 292. Liitulentus, Gyll., iii., 86 and iv. 565. — Bris, 512. — 

 Cox, ii., 193. — A very variable species both as to size, markings and 

 colour of the legs. Easily separated from all our indigenous species 

 except alisiDotis by its broad bilobed third tarsal joints, and from the 

 latter by the absence of the distinct pubescence on the upper surface 

 of the tarsi. The form with black tarsi has been considered a good 

 species by Thomson and other authors, and they are very likely right, as 

 it has some other points of difference besides the black tarsi. The 

 large form which I have included in my table has but few constant 

 characters to separate it. It has done duty for lutot<Ui, Gyll., in British
