HARPALIN.E 65 



convex and punctureless, the median stria distinct; elytra rather less 

 than one-half longer than wide, a little wider than the prothorax, the 

 sides parallel and feebly arcuate, the apex obtusely ogival, the sinus very 

 feeble; striae rather fine but impressed, deeply so toward suture and tip, 

 where the intervals become more convex, the scutellar short, fine and 

 oblique; dorsal puncture wanting, the lateral line of fovese inter- 

 rupted medially; anterior and middle tarsi (d 71 ) rather strongly dilated 

 and biseriately squamose. Length (cf ) 7.3 mm.; width 2.7 mm. South 

 Africa. 



It is of course quite possible that this species may already be 

 described under another name, but I have been unable to find any 

 reference to it. 



OSIMUS Mots. There are many characters in the type and only 

 species of this genus, the Acinopus ammophilus of Dejean, such as 

 the broad and Zabrus-\ike form of the body, very stout tibial spurs, 

 form of the head and long vestiture of the abdomen, which would 

 seem to validate Osimus as a genus, rather than a subgenus of 

 Acinopus, where it now rests; but my unfamiliarity with most of 

 the true Acinopi gives to these assumptions but little value. 



ACINOPUS Dej. The assumed type of this genus, in comparisons 

 which I have made with the preceding, is the species at present 

 listed as picipes Oliv. The body is of a peculiar compact, parallel, 

 convex and cylindric form, distinguishing it at once, not only from 

 any Harpalus, but quite as distinctly from Osimus. The genus 

 Acinopus appears to be peculiar to the palaearctic faunal regions. 



OPHONUS Steph. This genus was not considered to be distinct 

 from Harpalus by Lacordaire, though so esteemed by modern 

 European writers. In so far as the species before me, azureus 

 Fabr., is concerned, this is undoubtedly the proper course, but in 

 the recent catalogue of Heyden, Reitter and Weise, some other 

 elements are incorporated with Ophonus which do not belong there, 

 such for example as Harpalophonus Gangl., founded upon such forms 

 as hospes; this is undoubtedly a Harpalus, in its broad sense, and 

 has very little affinity with Ophonus azureus. 



RAPHALUS n. gen. The type of this genus, which is close to 

 Harpalus, may be defined as follows: 



*Raphalus convergens n. sp. Body oblong, moderately convex, 

 strongly shining, black, the under surface more piceous, the legs, antennae 

 and trophi pale testaceous; head fully two-thirds as wide as the prothorax, 

 slightly constricted behind the prominent eyes, the front very smooth, 

 with excessively fine straight epistomal suture, behind which the foveaa
