-equal to about half the length of the scape. Prosternum 

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

 visible from ahove. Median segment shorter than the meso- 

 notum, strongly narrowed to the apex. The whole insect 

 opaque, with pale golden pubescence thinly distributed, 

 fcecoining denser on tlie pronotuni, median segment, and 

 behind the eyes, and forming apical bands on the dorsal 

 segments of the abdomen^ Pygidial area triangular, punc-

 Easily distinguished by the extraordinary horns of tho 

 prosternum ; otiierwise it superficially resembles the West- 

 African G. ati-enuatus, Turn., but has the median segment 

 shorter and the eyes much fartiier apart on the vertex, in the 

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

 a link between the usual strongly convergent ejes of Gastro- 

 sericus and the parallel eyes of Paralellopsis. 



XXV. — Descriptions of a new Species and Subspecies of 

 Ennea from Northtm Nigeria, and a Correction in the 

 Original Description of E. reesi, Preston. By H. B. 

 Pkeston, F.Z.8. 



The species and subspecies described belovp- were received 

 through the kindness of Colonel A. G. Peile, and were 

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

 at Idah village, 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 autihor, also dealing with 

 Enneida3 from Nigeria *. In this paper the words placed ia 

 square brackets in the quotation below should be added to the 

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

 obliquely subtriangular, armed with 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, 

 the lower in each case being the stronger."
