142 STAPH YLINIDyE. [ScJllntogloSsa. 



S, viduata, Er. Eather broad and parallel-sided, very finely pubes- 

 cent, and with the front parts very finely punctured, dull black ; head 

 roimded, plainly narrower than thorax, antennae dark testaceous or red- 

 dish with the first joint usually lighter, second and third joints of about 

 equal length, 4-10 gradually a little thicker, but none of them trans- 

 verse, last joint almost as long as the two preceding together; thorax 

 broader than long with sides only slightly rounded, almost as broad as 

 elytra, obsoletely impressed before scutellum ; elytra about as long as 

 thorax (in tlie only pair I have seen they are somewhat shorter in the 

 female than in the male) ; hind body j)arallel-sided, finely and thickly 

 punctured, but a little less so and therefore a little more shining than the 

 front parts, sixth segment less closely punctured than the others ; legs 

 reddish testaceous. L. 3 mm. 



Male with the dorsal plate of seventh segment of hind body granu- 

 late, truncate at apex, very finely crenulate, and furnished at each side 

 with a minute tooth. 



Very rare j as far as I know it lias only been taken by Mr. Crotch ; in Dr. Sharp's 

 collection there is a pair labelled "Merton, Norfolk, G. K.. C." It has been several 

 times recorded from the Lake district, and from Scotland, bat the insects referred to 

 appear to have been H. eremita. (See Ent. Monthly Mag. ii. 46, 49, 88, &c.) 



GNVFSTA, Thomson. 



This genus was formed by Thomson to include three or four European 

 species that had previously been placed under Homalota ; M. Eauvel has 

 recently described a species from Australia, and Dr. Sharp has described 

 three from Central America, which are similar in appearance to the 

 European species, but, according to Dr. Sharp himself, two of them have 

 the intermediate coxse more distant : the genus is very closely related 

 both to Tachyusa and to Homalota, and it is hard to formulate the dis- 

 tinctions between them ; if, however, we include Gnypeta under Homa- 

 lota, we can hardly help sinking Tachyusa as well. 



1. Upper surface deep black, very shining G. labiits, Er. 



2. Upper surface with a distinct bluish reflection, somewhat 



duller G. CCEETILEA, Sahib. 



G-. labilis, Er. (c«r&o?;anff, Mann., nec Sharp). Black, very shining; 

 head nearly as broad as thorax, antennae moderately long, pitchy, with 

 base sometimes lighter, slightly thickened towards apex, joints 5-10 

 nearly equal in length, the penultimate being scarcely as long as broad, 

 eleventh about half as long again as tenth ; thorax about as broad as 

 long, considerably narrower than elytra, very finely punctured, with an 

 impression before scutellum ; elytra about one quarter longer than 

 thorax, very finely punctured ; hind body thickly and finely punctured 

 throughout, sixth segment rather more distinctly than the front ones ; legs 

 yellowish with femora a2.d more or less of tibiae pitchy. L. 2f-3 mm.
