CANAETAN COLEOPTEKA. 47 



hitherto beneath my notice. It was captured by Dr. Crotch, during 

 the spring- of 1862, in TenerifFe, but he cannot now recall the pre- 

 cise locality. It may at once be known by its flattened surface ; by 

 its pieeous-black hue and brightly rufeseent limbs ; by its elongate- 

 quadrate pro thorax being a little narrowed, and rather deeply and 

 thickly punctured, behind ; and by its coarsely crenate-striated ely- 

 tra having their short scutellary stria completely confluent with the 

 sutural one, and the outwardly- directed basal portion of the latter, 

 apparently, obsolete. In its somewhat parallel- oblong outline, de- 

 pressed surface, and deeply crenate-striated elytra, the P. Jiyuratus 

 is a little suggestive, at first sight, of an excessively diminutive P. 

 crenatus ; nevertheless when closely inspected it will be seen to be 

 totally distinct from that insect in all its characters ; and moreover 

 I believe that its main features will associate it rather with the 

 members of the Lagarus-groui^ than with those of Poecilus. 



(Subgenus Orthomus, Chaud.) 

 77. Pterostichus longulus. 



P. ater (vel piceo-ater), oblongus, nitidissimus ; prothorace subqua- 

 drato, ad latera svtbsequaliter rotundato, impunctato sed ad basin 

 utrinque foveis duabus (iaterna sc. Uneaformi subarcuata pro- 

 funda, sed externa breviore subrotundata plus minus indistincta) 

 impresso, per marginem basalem ijjsissimum angustissime margi- 

 nato ; elytris subparallehs, profunde crenato-striatis, interstitiis 

 paulo convexis, tertio punctis duobus impresso ; antennis, palpis 

 pedibusque piceis. 



Var. /3. discors [an species ?]. Prothorax ad latera magis rotundatus, 

 angulis posticis paulo obtusioribus, fovea basali externti subobso- 

 leta, elytrorum striis simplicibus nee crenulatis. [Teneriffa : a 

 Dom. Schaum communicatus.] — Long. corp. lin. 3-4|.

The present Orthomus appears to be identical with the Feronia 

 hngula of Keiche and Saulcy, for types of which, from Egypt and 

 Syria, I am indebted to Dr. Schaum. The Canarian specimens have 

 their elytral striae rather more decidedly crenulated than seems to be 

 the case in the Egyptian and Syiian ones ; and their prothorax is 

 quite impunctate, whereas in the example from Egypt there are
