68 CANAEIAN COLEOPTETIA, 



species lato diffusa, sub lapidibus per margines rivulorum nccnon in 

 aquosis, ab ora maritima usque ad 8000' s. m. ascendens. 



The T. curvimanus, which occurs sparingly in Madeira aud Porto 

 Santo, and which is so closely allied to the T. 4:-signatus of Medi- 

 terranean latitudes that Dr. Schaum thinks it may possibly be but 

 a small state of that species, is widely spread over the Canarian 

 archipelago, — where in aU probability it is universal ; for although 

 it has not yet been observed in Hierro, there can be but little doubt 

 that it must exist there likewise. In Lanzarote (where it was also 

 captured by Mr. Gray), Fuerteventura, Grand Canary, Teneriffe, and 

 Palma I have taken it, more or less abundantly ; and in Gomera (as 

 well as in Teneriffe) it was found by Dr. Crotch. It occurs at nearly 

 all elevations — in Teneriffe, for instance, from the immediate vici- 

 nity of S** Cruz to the Agua Mansa, and even to the Cumbre (ad- 

 joining the Canadas) above Ycod el Alto, more than 8000 feet above 

 the sea. My Fuerteventiiran specimens are from the Eio Palmas, 

 and the Grand-Canarian ones from the region of El Monte. 



104. Tachys haemorrhoidalis. 



T. niger, nitidus ; prothorace subcordato, convexo, ad basin utrinque 

 vix impresso ; elytris ovalibus, striis duabus versus suturam (ex-

Habitat in aquosis Canaria3, Teneriffe et Gomerse, sat rarus. 



Closely allied to the T. Lucasii (of Spain, northern Africa, Madeira, 

 tfec), but smaller, with its prothorax a little narrower and more 

 cordate, and almost free from impressions behind ; and with its elytra 

 more rounded at the sides, impressed with only two (instead of three) 

 striae towards the suture on each, with the two discal punctures less 

 conspicuous, and ornamented with a humeral (as well as a subapical) 

 blotch. The elytral patches, however, are often obscurely defined, — 

 being usually more or less suffused, or even subconfluent. With the 

 exception of the indistinct reddish blotch towards the shoulders (and 

 which is sometimes exceedingly faint), it seems to me to agree pre- 

 cisely with the T. hcemorrhoidalis of southern Europe, and Dr. Schaum 

 informs me that he can detect no other difference. Moreover in a
