120 STAPH VLiNiLi^E. [Humulvia. 



K. canescens, Sharp (sub-gen. Microduta, Muls. et Rey). This 

 species is rather closely allied to //. sordidula, but is broader and more 

 paiallel, with the antennse shorter, the terminal joint especially, the 

 latter point afibrding a good distinguishing character ; the punctuation 

 throughout is not quite so close and fine, but owing to its rather 

 thicker pubescence the Tipper surface is slightly duller ; the head is 

 rather broad; the antennae have joints 5-10 more distinctly transverse 

 than in H. sordidula ; the thorax is slightly more transverse, and the 

 elytra a little longer in proportion ; hind body scarcely nari'owed 

 towards apex, finely, evenly, and closely punctured ; legs pitchy yellow, 

 L. li mm. 



Male with the hind margin of dorsal plate of seventh segment much as 

 in H. celata, but with the four teeth smaller and more indistinct.

 Scotland, Solvvay district only ; it will probably be found in many other 1 icalities, as 

 most persons who work the Homalotce appear to find it in their ueighbourliood. 



This little group is perhaps the most difficult of all the Homalotce, not 

 even excepting the H. sericea group, which in some waj^s rather 

 resembles it. 



Group 19. 



This group contains seven species, one or two of which are very 

 distinct from the rest, and might well be separated from them ; tliey 

 occur'chiefly in dnng, but are occasionally found in moss and vegetable 

 matter ; the sexual characters are usually more or less obscure. 



H. cauta, Er. (jjulicaria, Er., parvtda, Mann., Atheta caufa, 

 Thoms., H. 2mrva of our catalogiies {^ parva, Sahib.), Badura j^on-a, 

 Muls. et Key). A small, black, shining species with rather rough 

 punctuation and pubescence ; head a little narrower than thorax ; 

 antennfe moderately long and not stout, joints 2-3 moderately long, 

 slender, third hardly as long as second, fourth about as long as bruad, 

 5-10 slightly transverse, eleventh joint gently pointed, quite as long or 

 rather longer than the two preceding together ; thorax a little narrower 

 than elytra, narrowed in front, rather strongly and roughly punctured, 

 with distinct outstanding hairs at sides, indistinctly channelled in front 

 of scutellum ; elytra a little longer than thorax, black or pitchy, a little 

 more closely punctured than thorax ; hind lody black, plainly narrowed 

 towards apex, .segments 2-4 distinctly and rather closely, fifth more 

 sparingly, sixth very sparingly punctured ; outstanding setae of sides and 

 apex very distinct ; legs pitchy, the four posterior tibiae each with two 

 fine exserted setae, of which the lower one is considerably the longer.
