which I have possessed for a good many years, without label or indication whence I 
obtained it, but I believe it was from M. Doue’s collection. I should think Upper 
Egypt is undoubtedly its country, and it may occur also in Senegal.

1149. Cybister crassipes, n. sp.—Minor, ovalis, robustus, latiusculus, parum 
elongatus, supra olivaceus, capite anterius prothoraceque ad latera late testaceis, 
elytris late testaceo-cinctis ; corpore subtus testaceo, prosterno pectoreque in medio 
obscurioribus, tarsis intermedius, tibiis tarsisque posterioribus piceo-rufis; elytrorum 
epipleuris versus apicem latis et planatis ; trochanteribus posterioribus apice libero, 
spinoso-acuto. Long. 22, lat. 12 m.m. 
I have not seen the male of this species: the female possesses a rather dense but 
fine sexual sculpture on the wing-cases and thorax; this sculpture consists of 
moderately fine scratches some of which are quite short, others elongate, at the base 
this sculpture extends from the scutellum to near the lateral margin, and it extends 
also two-thirds of the distance towards the apex, but becomes more distant both 
from the suture and lateral margin as it proceeds backwards; the thorax is nearly 
covered with irregular scratches but there are none at all on the head. 
The single individual I have seen indicates that this species is closely allied to 
Cybister reichei, but is of broad instead of narrow form.

1150. Cybister tibialis, n. sp.—Ovalis, sat latus, anterius evidenter angustatus, 
supra niger, capite anterius prothoraceque ad latera testaceis, elytris margine externo 
(cum epipleuris) testaceo-cinctis ; subtus piceus, pectore ad latera late testaceo ; pedi- 
bus quatuor anterioribus testaceis, tibiis intermediis piceo-testaceis, tarsis intermediis 
pedibusque posterioribus piceis ; elytrorum epipleuris versus apicem sat latis et 
planatis, Long. 30, lat. 16 m.m. 
The male has the anterior tarsi large attaining fully 3 m.m. in the transverse direc- 
tion ; on the intermediate tarsi there is a patch of quite shcrt sexual pubescence on 
each of the three basal joints, these patches are not very broad, that on the third 
joint being indeed quite narrow, the claws are rather elongate and little curved, the 
anterior one much thickened. The female has a largely developed sexual sculpture 
on the wing-case, consisting of elongate scratches or strize, which however scarcely 
anastomose with one another, they extend about three-fourths of the way to the apex, 
at the base they extend quite across the wing-case, and for nearly their whole length 
are but little separated from the lateral margin; on the thorax there are very fine 
short scratches on the lateral parts and extending along the base : the epipleurze are 
oblique, though not dilated in front of the middle. 
This species attains the size of the smallestindividualsof Dytiscusreeselii (No. 1169)
