236 Mr. H. W. Bates' supplement to the 



oculum haud lineam impressam emittentibus ; thorace 

 late cordato, antice valde rotundato ante basin con- 

 stricto, angulis posticis rectis, fovea utrinque basali 

 lineari ; elytris relative brevibus, sat convexis, apice 

 oblique sinuatis, profunde subpunctulato- striatis, inter- 

 stitiis paullo convexis 3io impunctato ; tarsis supra 

 pilosis. Long. 10 mm., $ . 



Oyayama, near Kumamoto. One example only in 

 March. 



Not much resembling any Ophonus known to me ; but 

 comes nearest 0. cordatus, differing, however, in the much 

 scantier punctuation. It resembles most Harpalus leptopus 

 and congruus, but has not the oblique line of the forehead 

 connecting the frontal fovea with the orbit, as in those 

 species. 



Harpalus vicarius, Harold. 



Harold, Deutsche Ent. Zeitschr., 1878, p. 66. 



Von Harold gives this name to the Japanese form of 

 H. ruficornis mentioned by Morawitz and myself as 

 having obtuse hind angles to the thorax. Among five 

 East Siberian examples I find nearly all the intermediate 

 gradations between vicarius and rufescens, but none with 

 hind angles so rectangular as in the European form. 

 Some males of vicarius, with smooth disc of thorax, 

 again connect the species with H. griseus. 



Harpalus tridens, Morawitz. 

 Morawitz, Beitr. z. Kaferfauna Ins. Jesso, p. 69. 

 Hakodate and Niigata ; Hagi (Miller). 



Closely allied to H. rugicollis, Motschulsky, and also 

 to the European H. calceatus. The extent of punctua- 

 tion and pubescence on the sides and apex of the elytra 

 varies. In one of Mr. Lewis' examples the whole elytra, 

 with the exception of the sutural interstice, is punc- 

 tured.

Von Harold identified this species from a type-speci- 

 men received from Motschulsky himself, and a small
