CANARIAN COLEOPTEEA. 461 



rather less equally rounded at the sides (or somewhat wider before 

 the middle than behind it), less bisinuated along the basal edge, and 

 with the hinder angles therefore perceptibly more obtuse ; and by 

 its elytra being very obsoletely substriated (a character, however, 

 which varies a httle in intensity), and more evidently rounded at the 

 sides, or less parallel towards their base. 



Genus 263. THALPOPHILA. 



Solier, Ann. tie la Soc. Ent. de France, iv. 370 (1835). 

 Although I should not myself have regarded the four insects enu- 

 merated below as more than aberrant Hegeters, for the acconmiodation 

 of which a separate Section might perhaps be desirable, nevertheless, 

 since they all have their epistome armed in the centre with a minute 

 tooth, and the &st of them is Ukewise remarkable for the greatly de- 

 veloped longitudinal plait on either side of its forehead (adjoining the 

 eye), I think that they may safely be referred to Seller's genus Thal- 

 pophUa, of which these two characters appear, from the diagnosis, to 

 constitute the essential features ; and moreover as the only described 

 member of that group (namely, the AMs abbreviata of Fabrieius) is 

 found in Senegal, it seems still further probable, even geographically, 

 that these five natives of the eastern portion of the Canarian archi- 

 pelago may be truly congeneric with the one from the African coast. 

 If such, however, should be the case, the structural formula of Thal- 

 popliUa wiU require a slight readjustment ; for the lateral carinse of 

 the forehead, the " depressed " body, the " rounded " angles of the 

 prothorax, the " cylindrical " antennal joints, and the " triangular " 

 scutellum are not more expressed (except perhaps the fii'st of them), 

 or more generic, than they are in Hegeter. But the mucronated epi- 

 stome is a character which seems to hold good in them all.

Habitat FuerteventiU'am, sub lapidibus parum vulgaris. 



This species has been observed hitherto only in Fuerteventura, 



where it was taken by Mr. Gray and myself near Puerto de Cabras
