Mr. J. Walton on the genus Apion. 393 



curved, rather stout, dilated on each side at the insertion of the 

 antennae, and gibbous beneath. Antennae medial, black, the basal 

 joint fulvous, longest, considerably dilated at the apex, forming 

 a pyriform club, the second oval, minute, three following exceed- 

 ingly minute, sixth and seventh very long, eighth stout, long- 

 obconic, the remainder forming an elongate club distinctly arti- 

 culated, the twelfth being minute, conic. Thorax subglobose, 

 dilated and rounded at the sides, above very convex, thickly 

 and deeply punctured, the punctures confluent, with a deep 

 dorsal channel. Elytra ovate, shining blue-black, very convex, 

 punctate-striate, the interstices broad, flat and coriaceous. The 

 mucro of the epigastrium elevated and dilated, armed on each 

 side with an acute tooth. Legs fulvous, robust, with the four 

 posterior coxa3, the lower half of all the tibise and the tarsi black ; 

 the anterior tarsi have the basal joint short and stout, armed at 

 the apex within with an acute tooth, the second joint at the 

 base within also armed with an acute tooth, which is parallel to 

 the first ; the four posterior tibise are distinctly stouter than the 

 anterior pair, bent, and each gradually thickened from the base 

 to the apex ; the two first joints of all the tarsi dilated ; the basal 

 joint of the posterior pair parallelogramical ; the three first joints 

 of all the tarsi, especially the posterior pair, concavo-convex, and 

 clothed beneath with a pulvillus. S- (Length 1^ line.) 



The female differs in having the head generally naiTower, 

 striated between the eyes, the frons posteriorly closely punctu- 

 lated; the rostrum longer, slender and filiform; the antennae 

 placed behind the middle of the rostrum, the basal joint black or 

 piceous, slender, a little dilated at the apex, the second long- 

 ovate, the six following nearly of equal length, long-obconie ; the 

 legs comparatively slender; the four posterior tibise as long as 

 the anterior, of equal thickness and nearly straight ; the two first 

 joints of all the tarsi slightly dilated ; the anterior tarsi and the 

 mucro of the epigastrium simple. 



This new and extraordinaiy species offers another example of 

 anomalous form peculiar to the male in the joints of the antennae 

 and in the construction of the legs. I first received a single ex- 

 ample with the collection of the late Mr. Millard of Bristol, which 

 I sent to -Germar as a new species, and he returned it labelled 

 *' dissimile ? " Specimens of both sexes were afterwards found 

 near Arundel in August, and rather plentifully amongst grass in 

 a field adjacent to Birch Wood in September, by Mr. S. Stevens 

 and myself.

The female of this species has sometimes a broad testaceous 

 ring at the apex of the anterior femora.
