234 PRIGENIA SQUAMOSA. 



diual ridge at the elytra a little inwardly from the shoul- 

 ders , covered with rather large round (vertex of the head), 

 ovate (thorax , scutellum and elytra) or elongate ovate 

 (pygidium , body beneath and legs) ochraceous scales (those 

 of the under surface and femora greyish) , placed into 

 punctures or scratches. The bottom and sides of the ex- 

 cavation of the head covered with erect elongate ovate 

 scales. The labium, antennae (especially the basal joint), 

 the ocular canthus, the top of the anterior coxae and the 

 under surface of the anterior tibiae covered with erect 

 hairs, the latter very densely so. The naked portions, 

 with exception of the clypeus, the outer surface of the 

 cephalic protuberances and the tibiae, without sculpture. 



Head very deeply excavated, sub-opaque by an aciculate 

 sculpture less distinct on the clypeus, the front margin of 

 which is truncated with rounded edges ; a smooth and 

 shining spot at the inner orbit in front of the ocular 

 canthus; the vertex very convex; the compressed cephalic 

 protuberances almost as long as broad at the base , slightly 

 convergent towards the top , the upper margin concave , 

 the front margin sinuated. The pronotum covered with 

 a scale-bearing sculpture , with exception of a longitudinal 

 line extending from the middle of the front margin as 

 far as the middle of the base, a rounded small spot on 

 each side of the median line at some distance of it and 

 just before the middle, and the raised lateral margins. 

 The base of the prothorax slightly bisinuate, the median 

 lobe less produced than in Prigenia Vollenhoveni , Mohn. •^). 

 The scutellum triangular, covered with a scale-bearing 

 punctuation , except the lateral margins and a longitudinal 

 median line. The elytra also covered with a scale-bearing 

 sculpture, except the top of the shoulders, a slightly 

 raised longitudinal ridge a little idwardly from the shoul-
