150 CISSID.^. 



IJinoderus substriatus, Payk. : the following details may, however, be 

 added, chiefly from Lesne's description : thorax narrower than the 

 elytra, broadly rounded in front, widened behind ; teeth of the marginal 

 row of the granulate portion of the thorax separate, posterior area of 

 thorax furnished with dull raised granules ; elytra strongly punctured 

 in irregular rows, each puncture on the dorsal region being accompanied 

 by a small projection ; posterior declivity furnished with upright and 

 rather long hairs ; on the basal half of the elytra the hairs are 

 sunk in the punctures and are invisible if viewed from the side : the 

 general colour is pitchy brown or lighter brown ; the elytra are some- 

 times shiny and sometimes dull; this is not a sexual character. 

 L. 6 mm. 



Extremely rare : I know of only one British specimen, which was 

 taken at Skellingthorpe Wood near Lincoln by the Rev. A. Matthews, 

 and is now in Mr. Gorham's collection : the species occurs on the 

 Continent and in Siberia, chiefly under bark of Pinus sylvestris. 



CISSID^. 



CIS, Latreille, 

 The following characters will be found useful for separating 

 C\festivus, Gyll., and C. vestitus, Mell. 



I. First ventral segment of abdomen of male 



rugose all over but with no umbilicate 



depression in the middle. . . . C. festivus, Gyll. 



II. First ventral segment of abdomen of 



male bearing a small umbilicate depres- 

 sion in the middle. ... C. vestitus, Mell, 



C. dentatus, Mellie (Ann. Soc. Ent. Franc. 1848, p. 324. pi. 3, 

 fig. 6). Elongate oblong, pitchy black, pubescent ; head deflexed, finely 

 punctured, concave in the middle with a small tubercle, anterior 

 margin sharply and narrowly emarginate and minutely bidentate in 

 the male, simple in the female ; thorax about as broad as long, 

 narrowed in front, with the anterior angles'subacute, anteiior margin in 

 the male with two distinct short teeth in the centre, sides margined 

 and rounded, base margined, posterior angles rounded, upper surface 

 finely punctured and pubescent ; elytra comparatively long, slightly 

 depressed towards suture on their anteiior third, uniformly and finely 

 punctured, pubescence yellow and rather shining ; legs ferruginouse 

 L. 1^2| mm. 



This species was introduced as British by Mr. Donisthorpe (Ent, 

 Record, xix. (1907) 130) on a single female specimen taken at Sandown, 

 Isle of Wight, in July 1907 by Mr. R. S. Mitford, probably by beating. 

 It occurs on the Continent in boleti on pine trees. It will probably be 

 found commonly in localities in the south of England.
