PANARTAN COLEOPTERA. 



which its generic features do not coincide with those given by de 

 Marseul, — which, however, I ought perhaps to add, do not completely 

 agree with the conclusions that I have arrived at even as regards the 

 ordinary European T. picipes. Thus, in the Teneriffan species the 

 mentum is semicircular (being regularly rounded, instead of emar- 

 ginated, in front), the second and third joints of the maxillary palpi 

 are subequal (instead of the former being much the longer of the 

 two), and the antennas have their club exceedingly solid and xm-dLn- 

 nulated (which, however, is equally the case in the T. picipes), the 

 first joint of their funiculus considerably enlarged and subglobose, and 

 the last (or anteclaval) one extremely thin and lamelliform. 



274. Teretrius cylindricus, n. sp. 



T. cylindricus, niger, nitidus, ubique punctulatus ; prothorace amplo, 



convexo,-\dx piceseentiore ; prosterno brevi, simplici (nee bistriato); 



mesosterno canaliculato, lobo antico magno ; pedibus rufo-piceis ; 



tibiis anticis extus 6-, posterioribus 5-spinosis. — Long. corp. linJl^ . 



Habitat Teneriffam sylvaticam ; ad Agua Garcia exemplar unicum

The present Teretrius is about the size of (or perhaps a trifle larger 

 than) the European T. picipjes, which at first sight it much resembles. 

 It is, however, a little broader than that insect, its prothorax (which 

 is slightly picescent) is convexer and more developed (it being pro- 

 portionally somewhat wider in front), its tibiae are more powerfully 

 spinulose (the hinder pair, wliich are more evidently curved, having 

 Jive spines along their outer edge, instead of only two), its prostemum 

 is rather shorter (being more broadly truncated at the apex) and free 

 from the two longitudinal costae which exist in that species, and its 

 mesosternum is channeled down the centre, with its anterior lobe 

 larger, or more produced. The proportions of its abdominal segments, 

 likewise, are not quite the same as in the T. picipes. The only ex- 

 ample of it which I have hitherto seen was captured crawling on the 

 inner canvas of my tent, whilst encamped at the Agua Garcia, in 

 Teneriffe, during April 1859.
