STAPHYLINID^. 55 



Mason's collection there is ii very small form of it, probably found by 

 Haliday in Ireland. 



As the name Diylossa, Haliday (1837), has been preoccupied in 

 Zoology (Wayler, 1832), Mr. Champion proposes to alter the name to 

 JJiglotta, but, as the name has not yet been accepted by the European 

 authorities, it is better, pei-haps, to retain Diglossa, at any rate for the 

 present. 



TACHYPORUS, Gravenhorst. 



T. fasciatus, Nicholson, Ent. Rec. 1911, p. 24. Broad, shining, 

 reddish-testaceous, with the head, breast, the sides and a broad 

 band at base of elytra, and hind body black. Head and thorax ex- 

 ceedingly finely punctured. Antenna long and fine, not thickened 

 towards apex, with base testaceous, darker towards apex, penulti- 

 mate joints longer than broad, 11th joint half as long again as 

 lOtho Elytra longer than thorax, with disc reddish, side mai^gins to 

 just before apex broadly black, a slightly zigzag and not very well- 

 defined broad band occupying nearly the basal half of elytra, black ; 

 where this band joins the marginal black bands it is narrowest, so that 

 here the reddish colour of the disc of elytra extends to nearly the base 

 on each side as a tongue-like projection ; very finely and closely punc- 

 tured, the punctures bearing a rather obvious black pubescence ; 

 marginal bristles stout and long. Hind body black, with the apical 

 margins of segments testaceous, finely and closely punctured. Mouth 

 parts and legs testaceous. L. 3J mm. 



This species in shape and size most closely resembles 2\ solutus,'Rv., 

 but the punctuation of the head, thorax, elytra, and especially of the hind 

 body is much finer. The antennfe, although of the same length, have 

 the penultimate joints considerably narrower. The 11th joint is only 

 half as long again as the 10th, whereas in T, solutus it is nearly tv/ice 

 as long. The elytra, besides the diflerence in colour, are more pubescent, 

 and the marginal bristles are stout and long ; in T. solutus they are 

 short and fine. From T. chrysomelinus, L., it difiers by its broader 

 form, by the colour of the elytra and the punctuation, which is closer 

 and deeper, and by the greater length of the antenna?, whose pen- 

 ultimate joints are not quadrate or slightly transverse, as in the latter 

 species. The marginal bristles of the elytra are even stouter and 

 longer than in T. chrysomelinus. 



Two specimens of this very pretty species were taken by Dr. G= W. 

 Nicholson by sifting sedge-refuse in Wicken Fen, one on April 24, and 

 the second on July 20, 1910. 



TACHINUS, Gravenhorst, 

 T. frigidus, Er., Gen. et Spec. Staph., 256. This insect appears to 

 be synonymous with T. pallipes and must therefore be so regarded. The 

 synonymy in the last European Catalogue is as follows, T, pallipes, Grav^ 

 = propinquus, M'akl. = frigidus, Er,
