In general outline and size the present Harpalus is closely related 

 to the tenebrosus; but, in addition to its wanting the obscurely 

 subcyaneons tint which is scarcely ever entirely absent from that 

 species, it may be known by its prothorax being shorter and more 

 transverse, straighter at the sides (causing the posterior angles to 

 be less obtuse), and more coarsely and sparingly punctured at the 

 base, by its elytra being more deeply striated, with their strite most 

 conspicuously crenate, and with their seventh interstice furnished with 

 a series of small punctures (varying from about two to six) behind, 

 and by its femora and tibiae being (instead of dark-piceous) bright 

 rufo-ferruginous — like the antennae and tarsi. Its subbasal anten- 

 nal joints, too, are not infuscated, as is the tendency in that insect ; 

 and the surface of its male sex is more highly polished. I had 

 thought at first, from its evident affinity with the H. tenebrosus, and 

 from the presence of the small series of punctiu'es towards the apex 

 of its eighth elytral interstice, that it might perhaps be identical 

 with the Eui'opean litigiosus ; but a type of that insect which has 

 lately been communicated by Dr. Schaum has convinced me that it 

 certainly is not conspecific with it ; and indeed Dr. Schaum himself 

 adds, " I consider it quite distinct, on account mainly of its strongly 

 punctured striae ; I know, in fact, of scarcely any Hmpalus which 

 has them so coarsely sculptured." 



I have taken it sparingly, from beneath stones, in Teneriffe (par- 

 ticularly around S'" Cruz and Orotava), in Palma (immediately above 

 Buenavista, before the ascent to the Cumbrc), and in the region of El 

 Golfo, on the west of Hierro. Whilst at Ycod el Alto, in Tenerifie, 

 during May of 1859, I obtained seven specimens (in the ravines of 

 the lofty Pinal between that spot and the Cumbre) which do not 

 entirely accord with those which I have found elsewhere ; neverthe- 

 less their difference is so slight that I think they cannot be regarded 

 as more than a variety of the litigiosus. Their prothorax and elyti'a 

 are, both of them, a trifle more convex than is ordinarily the case ; 

 and the former has its basal angles just perceptibly more obtuse.
