50 Mr. F. P. Pascoe on some new or little-hnown 



blue, covered with a sparse pale greyish pubescence ; eyes and meso- 

 sternum black ; rest of the body beneath, eyes and antennae pale yellow. 

 Length 2 lines. 



DoLiEMA [Tenebrionidae]. 



Head short, transverse. Eyes lateral, contiguous to the prothorax, par- 

 tially divided by the antennary orbit, larger below than above. Labruni 

 small, rounded in front. Mandibles thin, triangular, bidentate at the 

 apex. Antennae short, perfoliate, moniliform, and gradually increasing 

 in thickness from the fourth joint to the seventh or eighth. Mentum 

 subquadrate. Labium small, entire ; labial palpi stout, clavate, the 

 maxillary with its terminal joint subsecuriform. Maxillae two-lobed, the 

 lobes ciliated (the inner armed* ?). Prothorax depressed, contracted 

 behind, broadly emarginate in front, its anterior angles rounded. Elytra 

 very depressed, parallel, abruptly bent down at the sides ; the epipleural 

 plait narrow, terminating before reaching the apex. Legs short ; coxae 

 distant ; tibiae spmTed, the anterior serrated externally ; tarsi slender, 

 the first joint of the posterior as long as the last. Pro- and mesosterna 

 broad and flat, the former roimded posteriorly, and received into a slight 

 emargination of the mesosternum. 



A remarkable genus, which might readily be taken for a Pla- 

 tisus, but which is very closely allied to, if not identical with, 

 Mr. "Wollaston's Adelina. As, however, the characters of his genus 

 were drawn up from an insect which he suspects may not be con- 

 generic with certain representatives in the British Museum of 

 M. Chevrolat's original, but unpublished Adelina (but which unques- 

 tionably includes the species now to be described), and his detailed 

 description differs in several, although somewhat secondary points, 

 from that given above, and he has taken no notice of the peculiar 

 elytra, I have thought it better to consider my species the type 

 of another group ; and I do so with less hesitation, as the name of 

 Adelina has been long preoccupied by a genus of Gasteropods. 

 Doliema, thus restricted, has a remarkable range, D. platisoides oc- 

 curring in Ceylon, Manilla, and the Moluccas, while a closely- allied 

 species, differing in nothing apparently but in having a somewhat 

 broader head, is found in the valley of the Amazons. 



Doliema platlsoides. (PI. III. fig. 8.) 



D. pallide ferruginea, nitida j capite modice transverso ; prothorace pos- 



tice bifoveolato. 

 Hah. Moluccas (Batchian) ; Ceylon ; Manilla. 



Extremely depressed, pale rusty testaceous, shining, and very mi- 



* With a high power of the microscope, I cannot satisfactorily determine 

 whether the inner lobe of the maxillce be armed or not.
