108 Mr. F. P. Pascoe on some new or little-known 



yellowish hairs more conspicuous on the head and prothorax, but in- 

 definite as to outline and varying apparently in different individuals ; 

 body beneath black; legs with a few scattered hairs only. Length 

 2 lines. 



Dastarctjs [Colydiidae]. 



Walker, Ann. and Mag. Nat. Hist. 3 ser. ii. p. 209. 

 Dastarcus conjinis. (PI. VI. fig. 6.) 



D. elongato-ovatus, fuscus ; prothorace elytrisque costatis, costis ferru- 

 gineo-hirtis. 



Hub. New Guinea (Dorey). 



Elongate-ovate, dark brown, with stout, stiff, dilated, pale rusty hairs 

 (or scales), which are chiefly confined to costae and other elevations on 

 the upper surface ; head small, partially retracted in repose ; prothorax 

 with two waved grooves on each side, the outer smallest, and fringed 

 with stiff hairs ; scutellum scarcely visible ; elytra punctato-sulcate, 

 the costae between them closely covered with stiff hairs ; body beneath 

 coarsely punctured, with a setaceous hair in the centre of each ; palpi 

 ferruginous. Length 5 lines. 



Larger and stouter in proportion in all its parts than the Cey- 

 lonese D. porosus, but otherwise very closely allied. 



I am unable, at present, to give any oral details of this curious 

 genus, which Mr. Walker has only very briefly characterized, at the 

 same time associating it with the Hydrophilidae ; it is, however, an 

 undoubted Colydian, and evidently nearly allied to Emmaglceus of 

 M. Leon Fairmairc. The large primo-abdominal segment and distant 

 posterior coxae suggest also an affinity with Bothrideres and Derata- 

 phrus ; but its head, vestiture, and habit altogether, point to a distinct 

 subfamily. It may be mentioned that all the coxae are widely 

 apart; the femora canaliculate beneath for the reception of the tibiae, 

 which are fringed with stiff hairs externally, and the anterior ter- 

 minated by two spines, the inner of which is much longer and curved, 

 whilst the outer, under a strong lens, is seen to be tridentate ; the 

 mouth is almost entirely closed below by the prolonged mentum ? (as 

 in Derataphrus), the small, pointed maxillary palpi protmding at the 

 sides. 



Bothrideres [Colydiidae]. 



Bothrideres succineus. (PI. V. fig. 3.) 



B. niger ; prothoracis angulis anticis subacutis, ecostatis ; elytris striatis, 

 tuberculatis, medio succineo-granulatis. 



Hub. Brazil (Rio ; Para). 



Dull black, opake ; head covered with rather distant, shallow punc- 

 tures ; prothorax remotely punctured, longer than broad, considerably
