segmenti basalis apicem fere attingentes; pedes mediocres;; 

 tibiie minus fortiter compressce ; unguiculi appendiculati. 



The loss of the anteniue in my exponent of this genus is un- 

 fortunate ; these members are very short, with the club propor- 

 tionally large and the joints preceding the club very minute, so 

 far I have been able to ascertain, but I destroyed the one 

 antenna I had succeeded in distinguishing while trying to count 

 the joints. Tliere will, however, be no difficulty in identifying 

 the genus without a detailed description of the antenna?. The 

 clypeus and cheeks are continiious, and formed almost exactly as 

 in Orcus, This character combined with the following will, I 

 think, distinguish the genus from all hitherto named genera of 

 CoccinellidcF, viz., anterior tibiae simple, prosternum evenly con- 

 vex in front of the anterior coxae, ventral segments only five, 

 body pubescent, ej^ipleural foveae very well defined, epipleurae 

 narrow (e.(/., much narrower than in Bucohis) and horizontal, legs 

 not received in repose in sulci of the undersurface. 



N.B. — I have not been able to satisfy myself as fully as I could 

 wish regarding the structure of the mesosternum ; indeed, I have 

 failed to detect any suture between the meta and mesosterna 

 under a fairly good microscope. It is just possible that an ex- 

 cessively fine suture may have escaped my observation, but I 

 think it more probable that the suture is in contact with the 

 hind margin of the prosternum, the mesosternum thus being (in 

 part at least) vertical, and only observable by dissection. There 

 is some approximation to such a structure in Serangium and other- 

 genera of CoccineUidre w^here only a very short transverse strip 

 of mesosternum is visible without dissection. 



X. angidatus, sp. nov. Late ovalis ; sat convexus ; nitidus ; 

 piceo-niger, apicem versus obscure dilutior ; capite 

 prothoraceque subtiliter crebre, elytris pauUo fortius sparsius,. 

 punctulatis. Long., 1 1. ; lat., * 1. (vix). 



The whole body is of a nearly uniform pitchy black colour, the 

 elytra slightly paler towards the apex (perhaps only in occasional 

 examples). The prothorax is about twice as wide as long, its 

 sides very strongly deflexed so as to be almost vertical ; the front 

 margin is sinuated behind the eyes ; its sides are but little 

 rounded ; its front angles though not at all sharp are fairly 

 defined and rather prominent, its hind angles roundly obtuse ; 

 the base bears a fine impressed line close within the margin and 

 is strongly convex (or w^idely lobed) all across the middle, being- 

 somewhat angular in front of the scutellum ; the puncturation of 

 the surface becomes coarser and subrugulose near the lateral 

 margins where it is perhaps a little stronger than that of the
