16. Chalciosphcerium enderleinf, sp. n. 



Oval, very convex, shining, seneous or greenish-aeneous 

 above, ameo-piceous beneath, the antennas and legs in great 

 part piceous; somewhat thickly clothed with long, erect, 

 bristly, brownish hairs (all easily abiaded), the under surface 

 and legs also pubescent ; the head and prothorax rather 

 closely and conspicuously, the elytra more sparsely and irregu- 

 larly, punctate; beneath very closely, the metasternum more 

 sparsely, punctured, the concave pro- and epi pleura much 

 smoother. Head large, broad ; antennae rapidly widening 

 outwards, joints 6-10 strongly transverse, 11 ovate, about as 

 long as 9 and 10 united, 7-11 forming an elongate, lax club. 

 Prothorax rapidly narrowing from the base forward, the sides 

 (viewed laterally) almost straight, the hind angles sharp. 

 Scutellum wanting. Elytra model ately long, rapidly, arcu- 

 ately narrowing from the base, somewhat acuminate at the 

 tip. Prosternal process bioad, rounded at the apex, which is 

 received in a smooth deep cavity in the n esosternum. Tarsi 

 with a narrow pencil of hairs at the apex of the third joint 

 beneath, the fourth joint very small. iEdeagus : lateral 

 lobes very long and acuminate, the long penis-sheath also 

 acuminate and curved downward at the tip.

 (A/. Cameron}. 



Described from a perfect male captured by Mr. Cameron in 

 Dec. 1914. Two others, imperfect and abraded ($ $?), 

 found in the Falklands in 1860, and presented by Mr. Havers 

 to the British Museum in 187H, seem to belong to the same 

 species. The unique type of the genus, C. so(ox, is a larger 

 and broader insect (length 3f, breadth 2\ mm.), and much 

 more rounded at the sides (to judge from Enderlein's figure), 

 and it has a long lobe or spiniform process at the apex of the
