/ 
thickly punctured, antenne short ; thorax convex, transverse, very finely 
punctured, narrowed in front, with sides and base finely margined ; 
scutellum triangular; elytra as broad as thorax, with a tulercle at each 
shoulder which is usually light-coloured, with rather regular rows of 
punctures set in fine striz, interstices very slightly convex and furnished 
with rows of short whitish hairs; legs rather slender. L. 2 mm. 
In powdery fungus, on old fir stumps, and on decaying beech trees; rare; Esher 
(Power); Cobham Park (Walker); Chatham; Weybridge; New Forest; Cannock 
Chase (Blatch) ; Scarborough (Lawson). 
CISSIDZ. 
The Cisside, or Cioide, as they are called by some authors, are in 
several points closely connected with the Bostrichidw, and may possibly 
be regarded as a feeble and depauperized form of that family; they 
comprise a few genera of small and insignificant insects, which are 
widely distributed in both tropical and temperate countries, and are 
found in fungi on old wood, or in decayed wood which is more or less 
infested with fungoid growth. The following are the chief characters of 
the family :—Forehead prone, head and front of thorax often horned or 
furnished with lamelle in male, antenne 8-10-jointed, with the last 
three joints forming a loose club, inserted under the raised margin of 
the forehead ; thorax margined at sides, more or less cylindrical, anterior 
coxal cavities narrowly closed behind ; elytra entirely covering abdomen, 
the latter composed of five segments, of which the first is longer than 
the following ; tarsi 4-jointed, with joints 1-3 very short, equal, and 
the last much longer than the remainder taken together; the general 
form is short and convex, and the upper surface, as a rule, is rather 
strongly pubescent. 
The larvze of the Cisside bear some analogy to those of the Ptinidw, but differ in 
having five ocelli on each side of the head, and in the formation of the last segment 
of the abdomen, as well as in other points; the larva and pupa of Cis boleti are well 
figured by Mellié (Monographie de Vancien genre Cis, Annales de la Sociéte Entomo- 
logique de France, 2nd Series, vol. vi., plate 10, fig. 6 and 6a); the larva is fleshy 
white, cylindrical, rather curved, somewhat broader in front than behind, with the 
head round, smaller than the prothorax, and the remaining segments of much the 
same character until the last, which is not longer than the preceding, and bears two 
rather long spines, which are slightly curved towards the back; the antenne are 
short, 3-jointed, and the legs are moderately long; the two spines on the last segment 
seem to be characteristic of all the species of Cis ; the pupa also is furnished with a 
somewhat similar pair of spines, and is rather strongly contracted towards apex; it 
does not, however, present any further peculiarities that call for particular notice, 
Out of the five European genera four are found in Britain; these may 
be distinguished as follows :— 
I. Antenne 10-jointed. 
i. Anterior coxz trausverse, round oval; tibiw not (or 
very rarely) dilated at apex . . . . . . . . Crs, Latr. 
ii. Anterior coxee shorter, more or less conical ; tibiz 
dilated and denticulate at apex. . . . . . . WnopaLtoponrus, Mell.
