126 DR. J. E. T. AITCHISON ON THE ZOOLOGY OF 



Variety. — A smaller specimen (11 lines long) differs from those above described in 

 being much more shining, the elytra more convex and very smooth. 



This species closely resembles B. ominosa in its general form ; but is at once distin- 

 guished from its congeners by the form of the apex of the elytra. 



Sab. Between Quetta and Khusan. 



26. Beaps felix, sp. n. (Plate XIV. fig. 12.) 



Nigra, parum nitida ; thorace subquadrato, parum convexo, sat crebre punctato, 

 lateribus paulo elevatis, postice levissime sinuatis, antice rotundatis ; elytris modice 

 convexis, apice cordatis, marginatis, sat fortiter irregulariter punctatis, obsoletissime 

 striatis. Long. 18 lin., lat. 6f lin 



The punctuation of the head is distinct, not very close, except at the back, where it is 

 crowded and rough. The thorax is unusually flat, gently convex on the disk, with the 

 fine margin slightly reflexed ; the punctures are moderately strong, moderately close 

 together, but more distant on the disk. The elytra are very slightly convex at the base, 

 a little more so posteriorly, gradually declivous at the apex ; the fine margin is very 

 conspicuous from above near the shoulders, but is lost sight of at about oue third from 

 the apex, appearing again at the apex ; the apex is produced horizontally for about 

 four millimetres. In some lights the elytra are seen to be slightly striated. The 

 punctures are moderately strong, frequently subconflueut transversely, very slightly 

 asperate. The tibiae are asperate, subcylindrical.

27. Prosodes diversa, sp. n. (Plate XIV. figs. 10, 11.) 



Nigra, subopaca; thorace basi parum angustato, subtiliter sat crebre punctulato, 

 disco paulo convexo, lateribus deplanatis, marginibus perparum elevatis ; elytris 

 fere lsevibus, dorso perparum convexo, ad latera et apicem declivis ; tibiis tenuiter 

 asperatis ; tarsis bene compressis ; antennarum articulo 7° lato. 

 d . Angusta ; pedibus longioribus. Long. 12J lin., lat. 4J lin. 

 2 . Lata. Long. 13 lin., lat. 6 lin. 



The antennas are rather short ; the seventh joint about twice as broad as the preceding 

 joint, somewhat triangular. The thorax has a slight impression at each anterior angle, 

 and at the base there is in most of the examples a curved transverse impression at the 

 base (interrupted in the middle), and there is a shallow impression within each posterior 

 angle. The surface at the posterior angles is somewhat rugose. The elytra have 

 numerous short, irregular scratches, and here and there a very small puncture may be 

 traced. Iu the male the sides are almost vertical ; in the female slightly turned under. 

 Sab. Badghis and Hari-rud valley. 



This species is allied to P. oblusa, but is quite differently sculptured, and flatter on 

 the back of the elytra, &c. 



One female example has the elytra wrinkled all over, evidently from some accidental 

 cause.
