ST. HELENA. 
on the elytra or wing-covers. It inhabits both the high and low 
land, but chiefly the north-eastern quarter of the Island, where it 
may he detected, generally in pairs, under stones, or sometimes in 
broad daylight walking across a roadway, in the neighbourhood of 
Eupert’s Valley or Longwood. Mr. Wollaston says: “It seems to 
belong to the same type as the African species senegalese and 
rugosum, from the former of which it is nevertheless abundantly 
distinct. From the latter it differs {inter alia) in being more 
depressed, and in having its coppery punctures smaller, in its pro- 
thorax being more deeply rugose before and behind, and in its legs 
being less robust.” This creature emits a most unpleasant odour 
when taken in the hand, and is frequently covered with very small 
parasitic insects. 
*C. helense, Hope.— A Beetle very like the last species in 
appearance, but smaller and blacker, and perhaps more generally 
distributed in the Island. 
Pristonychus, Dej. 
P. complanatus, Dej.-A glossy black Beetle, rather more than 
half an inch m length, inhabiting the high land of the central parts 
of the Island; found under stones, fallen trunks of trees &c Mr 
Wollaston writes of it thus: “It is a species of Mediterranean 
latitudes— occurring in Portugal, Spain, the South of France Ttaly 
Sardinia, Sicily, Egypt, Barbary, &c. It is abundant also in the 
zores, Madeiras, and Canaries, and has been reported even from 
Chili. 
Bemhidium, Auct. 
*B. mellissii, Woll.-A very beautiful little light-brown Beetle, 
one-sixth of an inch m length, taken from the high land, of which 
Mr. Wollaston writes, that “ it belongs to the same group as the 
European B. varium and flammulatum. It is well distinguished by 
its dull brassy-green head and prothorax, and lurid-testaceous elytra— 
the latter of which are ornamented with a number of darker fascia? 
and cloudy patches, forming (on each elytron) a large sub-apical 
blotch, a postmedial zigzag (or deeply dentate) fascia, and two 
squarish ante medial spots placed in an oblique direction (from the 
shoulder) on the fore disk. The elytral stria? are coarsely and 
closely punctured, or crenate, and there are two large punctiform 
impressions on the third interval from the suture.”
