404 On new Species o/'Histeridai. 



commencing behind the eye and joining one another ante- 

 riorly, enclosing a triangular space, which is smooth in front 

 and rugose behind ; before the neck are three costse, the 

 median one much the longest ; thorax, lateral margin elevated, 

 with a conspicuous carina on each side which corresponds to 

 the second elytral costa ; behind the neck are four shortened 

 costEe placed at equal distances ; elytra have 5 setose costge, 

 the two sutural being close together and less raised than the 

 others, the interstices have two rows of very large punctures, 

 interspaces smooth ; propygidium and pygidium very rugose ; 

 prosteruuui, the sides are carinate, the carinas are not sinuous, 

 but approach a little anteriorly, at the base there is a round 

 shallow impression ; the mesosternum is bisinuate in front, 

 with aroughly fashioned fovea of irregular outline at each ante- 

 rior angle, it is not distinct from the metasternura, and both 

 are deeply pitted with large round punctures, not thickly nor 

 regularly set ; the median line of the metasternum is fine and 

 interrupted by the punctures. 



This species resembles 0. costipennis^ Fahr. ; the deep and 

 round punctures in the sterna are a distinguishing character. 



Hah. Zanzibar (Bagamoyo, RaJ^rai/). 



Onthoj^Julus hipartitus, Lew. — On further examining a 

 series of tliis species I find that it is distinct from 0. costi- 

 Ijennis^ Fa'ir. 



Culonides parvulus, sp. n. 

 Ovalis, niger, subopacus, pedibus rufis ; fronts excavata ; pronoto 

 lateribus elevatis, punctatis ; elytris striis 1^-4'" integris, suturali 

 postice obsoleta ; propj'gidio transversim prorninulo; tibiis dilatatis. 

 L. 1| mill. 



Oval, black, somewhat opaque, legs reddish ; head carinate 

 over the eyes, longitudinally excavated in the middle, sides of 

 excavation raised ; thorax anteriorly as wide as long, base a 

 third wider, somewhat closely punctured throughout, sides a 

 little elevated, with a shallow .«ulcus within the lateral mar- 

 gin, commencing behind the anterior angle and widest near 

 the middle, scutellar fovea feebly impressed ; elytra punctate 

 like the thorax, striae 1-4 complete and strong, with the inter- 

 stices depressed, giving the stria3 a rai?ed appearance, all are 

 parallel to each other and a little bowed, tlie fourth at the base 

 approaches the sutural, sutural straight and wider than the 

 others anteriorly, apically evanescent; propygidium punctulate 

 and apically built up and projecting over the pygidium ; pygi- 

 dium feebly convex, closely but not densely punctured ; pro- 

 sternum, tlie keel is narrow, flat, incised at base, anterior lobe 

 minutely and rugosely punctate ; mesosternum produced ante- 

 riorly, bisinuous, transverse stria fine, straight, feebly crenulate, 

 and on each side it merges into a strong and very conspicuous
