are seen on the basal part of the elytra, when viewed in a favour- 

 able light and position. The male of C.fiiscula has a minute 

 denticle near the apex of the anterior tibia on the inner side. 

 This species is as common as the preceding. It is remarkable 

 that this very common insect is not described by Stephens ; it 

 stands in his Cabinet under the name " Sulcicollis," and the de- 

 scription given in the " Illustrations," p. 109, sp. 9, which is taken 

 from Gyllenhal's account of Latrldius iransversulis (see Gyll. iv. 

 133, 11), was evidently supposed to belong to this species; it, 

 however, belongs to an insect of which I have seen no British 

 example. In Stephens' " Systematic Catalogue," C. sulcicollis of 

 Kirby's MSS. is given as = L. transversalis of Gyllenhal, but ac- 

 cording to Kirby's Collection the insect is = C.gibbosus of Gyll., C. 

 impressa of Kirby's Collection being = L. fusculus of Gyllenhal. 

 I cannot think that Kirby is correct in refeiring this to the C. im- 

 prcssa of Marsham.
