jne the head is drawn into the cavity of the prothorax so closely 

 and exactly that the front margin of the epistoma is in contact 

 along its entire length witli the front margin of the prosternum, 

 and the oral organs (except the antenni^e) are completely hidden ; 

 the structure in this respect resembling that of Cryptolronus. 

 S. mysticum, sp. nov. Late ovale ; sat convexum ; nitidum ; 

 ferrugineum, piceo-umbratum ; longe nee crebre albido- 

 pubescens ; supra fere impunctatum ; subtus segmentis ven- 

 tralibus antice subtiliter sparsim, postice crebrius subrugulose, 

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

 The general colour is a deep reddish-brown, the head and thorax 

 pitchy, the general colour clouded vaguely with piceous about the 

 suture and margins of the elytra and on the breast. The pro- 

 thorax is rather small in proportion to the elytra ; it is quite 

 twice as wide as long ; its front margin is sinuated behind the 

 eyes ; its sides are strongly rounded (somewhat angulated in the 

 middle), and all its angles are rounded off; a delicate impressed 

 line runs immediately in front of the hind margin. The super- 

 ficial appearance is that of Scymnus. Under a very strong lens 

 the prothorax shows some excessively fine puncturation ; I cannot 

 discover any on the elytra without using a microscope.

BUCOLELLUS, gen. nov. [Bucolo affinis]. 

 Corpus pubescens ; caput prothoraci mediocriter insertum ; an- 

 tennarum brevium basis aperta ; oculi sat magni, sat sub- 

 tiliter granulati, intus subparallela ; epipleuras antice sat 

 lat^e subhorizontales, postice gradatim angustativ et magis 

 verticales, contra pedes intermedios et posticos profunde 

 foveatjB ; prosternum breve, sat ^qualiter convexum, in 

 medio longitudinaliter nee carinatum nee depressum ; mesos- 

 ternum sat magnum, antice truncatum ; abdomen segmentis 

 5 (apicali pri^cedentibus 2 conjunctis longitudine a^quali) 

 conformatum ; suturre ventrales bene impressa^ ; lamellae 

 abdominales segmenti basalis apicem attingentes, hujus cum 

 margine apicali postice conf usae ; femora minus compressa ; 

 tibia; sat graciles ; unguiculi appendiculati. 

 This genus is certainly, I think, near to Bucolus, from which 

 it differs chiefly in the shorter antenna?,* in the incomplete ven- 

 tral lamella^, and especially in the excejDtionally short prosternum, 

 this being in Bucolus exceptionally long. 



B. ornatus, sp. nov. Breviter ovalis ; pubescens ; sat convexus ; 



* I have examined these under a microscope as well as possible without injury 

 to the type, and find that they appear to consist of ten joints, but it is not pos- 

 sible to be quite certain without examination under more favourable conditions.
