Genera and Species of Coleoptcra. 351 



TmchystoJa (jvaiudata. 



T. nigra, tota pube fiisco-forriiginea induta; elytris seriato-graimlatis, 

 scriebus cluabus regioiie sciitellari abbreviatis. 



Hah. ]5oriu>o. 



Black, opake, every^vllorG covered with a short, dense, brownish-fer- 

 ruginous pubescence ; head neither punctured nor sulcated in front ; 

 prothorax transversely channeled anteriorly, five Hattish tubercles on 

 the disc, aiTanged [', a stout spine at the side; scutellum titans versely 



subcordate j el}^ra a little depressed on the basal two-thirds of their 

 length, rapidly sloping beyond to the apex, on each nine rows of shining 

 black granules, the inner row distant from the suture, and its granules 

 oblong or almost linear, near the scutellum six granules in pairs, the 

 second row of granules from the suture extending to half the length 

 of the el}i;ra, space between the suture and inner row with two irre- 

 gular lines of impressed punctures, nearly all the granules with a deep 

 puncture behind. Length 11 lines. 



This species differs from a Java congener in the British Museum, 

 labelled Tracliystola scdbripennis (Dej.), in the smaller punctures 

 along the sutural margin, in the second row of granules extending 

 to at least half the length of the elytra, instead of only a quarter, 

 and the double row near the scutellum, whilst there are only two or 

 thi'ee altogether in T. scahripennis. A third species from Borneo, 

 also closely allied, is in the same museum. 



Brimus [Lamiidae]. 



Head nearly as broad as the prothorax, quadrate in front. Antennre 

 longer than the body, setaceous, arising from short tubercles, distant at 

 the base, the first joint massive, subcylindrical, tlie third as long as the 

 first, the rest subequal. Eyes lateral, widely emarginate. Palpi 

 slender, the terminal joint ovate. Prothorax subquadrate, strongly 

 spined at the side. Elytra connate, tapering tow\ards the apex in the 

 male, ovate in the female, the base spined. Legs moderately long, 

 anterior and intermediate coxae remote, femora subclavate, tibia3 spined, 

 tarsi short. Presternum simple, mesostemum truncate posteriorly. 



Proposed for the reception of Borcadion ? spmipenne (Trans. Ent. 

 Soc. 2 ser. iv. p. 252), which I described from a female specimen in 

 the collection of W. W. Saunders, Esq. There are now five examples 

 in the British Museum, and from one of them, a male, I have drawn 

 up the above characters. Brimus differs from Dorcadion (to which 

 ' I doubtfully referred it) in the presence of antennary tubercles and 

 the greater length of the mesothorax, so that the anterior and middle 

 coxae (as well also the posterior) are separated from each other by a 

 considerable interval, not crowded together so as to be almost in con-
