equal to about half the length of the scape. Prosternuin 

 produced on each side into a stout, acute, curved horn, plainly 

 visible from above. Median segment shorter than the meso- 

 notuni, strongly narrowed to the a|)ex. The whole insect 

 opaque, with pale goklon |)ubescence thinly distributed, 

 becoming denser on the jironotum, median segment, and 

 behind the eyes, and forming apical bands on the dorsal 

 segments of the abdomen. Pygidiul area triangular, punc- 

 tured and bare. Second abscissa of the radius very short ; 

 the two recurrent nervures meeting before joining the cubitus.

Easily distinguished by the extraordinary horns of tho 

 prosternum ; otherwdse it superficially resembles tlie West- 

 African 6^. atfenuatus, Turn., but has the median segment 

 si)orter and the eyes much farther apart on the vertex, in the 

 latter feature resembling G. lamellatus, Turn., and forming 

 a liidv between tiie usual stronglv convergent ejes of Gastro-

XXV. — Descriptions of a new Species and Subspecies of 

 Ennea from Xorthtrn Nvjeria, and a Correction in the 

 Original Description of E. reesi, Preston. ]^y H. 13. 

 Preston, F.Z.8. 



The species and subspecies described below were received 

 through the kindness of Colonel A. Gr. Peilo, and were 

 obtained by Mr. H. Cadman, of tiie Colonial Civil Service, 

 at Idah vilhige, at an altitude of 1300 feet, 25 miles north of 

 Abuja, Zaria Province, Northern Provinces, Nigeria. The 

 author has much pleasure in dedicating the new species, a 

 most interesting form, to the collector. 



It may, perhaps, not be out of place to here make a small 

 correction in a former paper by the autlior, also dealing with 

 Enneidse from Nigeria *. In this paper the words placed in 

 square brackets in the quotation below should be added to the 

 last lines of the diagnosis of Ennea reesi, thus : — " Aperture 

 obliquely subtriangular, armed wnth a projecting, parietal, 

 lamella-like tooth, two denticles on the inner margin of the 

 [labrum and two on the inner margin of the] columella lip, 

 tlie lower in each case being the stronger."
