250 Mr. Gray on new Helicince. 



lines to 1 \ lines ; all distinctly sex-dentate, with three spines at 

 their apices. Posterior legs very spinose and hairy. Inhabits 

 the Southern steppes of Orenbourg. 



3. Lethrus Podolicus ; totus niger, thorace laeyi, elytris rugosulis. 

 Long. 6 lin. lat. 4 lin. 

 Lethrus cephalotes, var. minor, Besser in Uteris. 



Rather larger than the preceding, but as it appears to me distinct 

 from L. cephalotes. Head -with a broad rather square clypeus, 

 porous ; the mandibles marginated on the outside, beneath with a 

 strong, rather incurved, abbreviated tooth. The auricles seem to 

 form a single appendage. Antennae proportionably longer and 

 thicker than in L. cephalotes. Thorax smooth as in that species, 

 but more reflected on both sides and behind. Scutellura very nar- 

 row, acuminated. Elytra rather rough, with impressed obliterated 

 lines. Body beneath somewhat porous, feet pruinose, anterior 

 legs serrated, smooth, with bristles, and one spine at the apex. 

 Inhabits Western Podolia. 



Art. XXXIII. A Description of Two new Species of 

 Helicince, and Explanation of the Figures to the Mono- 

 graph. Bi/ Mr. J. E. Gray, M.G.S. 



Having observed two new species of this genus on my late visit, 

 in company with my friend Mr. Children, to the superb collection 

 of the late Lord Tankerville, I have sent you a description, which 

 I took at the time, to render my Monograph more complete, hoping 

 in a short time to be able to give figures of them ; to which I have 

 added an explanation of the figures of the other paper. 



1*. Ilelicina Tankervillii. 



Tesfa subgloboso-conoldea, acute carinata, spiraliter squamu- 

 losa costo-striata, supra conica, infra convexa ; peristoraate reflexo 

 albido, labio medio sinuato, columella subincrassata.
