38 Mr. D. Sharp on the Bruchida of Japan. 



striatis ; striis fortiter punctatis. Long. 3| millim. (capite 

 intiexo). 



Very similar to the well-known European S. cardui, but 

 rather larger than the largest examples thereof, and readily 

 distinguished by the more abundant pubescence^ which is ot" 

 sordid very dark grey colour, and a little variegate, more 

 especially on the pygidium, and by the much more conspicuous 

 punctuation of the elytral strige ; the front coxaj are more 

 distinctly separated, the middle legs more widely distant, and 

 the mesosternum less prominent and less exposed at its apex. 



One example ; found on the sand-hills at Hakodate. 



Pygobruchus (nov. gen.). 



Pygidium e sogmeutis tribus compositutn. Coxae anteriores elongatae, 

 contigiiEe. JFemara posteriora gracilia, tibiae absque calcaribus. 



This insect has the appearance of a convex Bruchus^ but is 

 very different on account of the peculiar structure of the 

 pygidium ; this is elongate, and about one half of its length 

 is occupied by the last dorsal segment ; the penultimate seg- 

 ment exposed is also large, but the antepenultimate is much 

 shorter. 



Pygobruchus scufellan'Sj n. sp. 



Niger, griseo-pruiuosus ; protliorace couico-transverso, fortiter punc- 

 tate ; scatello elongato, apice bidentato ; antennis (maris) flabei- 

 latis. Long. 85 millim. 



Antenngp, elongate, entirely black ; second joint minute, third 

 elongate, giving off from the middle a rather long process, 

 the following joints armed with still longer processes. Head 

 short ; eyes rather large, widely separated. Thorax much 

 narrowed in front, the sides very little rounded at the front 

 angles ; the whole surface coarsely punctate and evenly covered 

 with a somewhat scanty griseous pubescence. Scutellum 

 elongate, with prominent extremity, which is deeply notched. 

 Elytra rather deeply striate ; the internal strire crenate, the 

 outer punctate rather than crenate, and becoming behind 

 effaced so as to form there rows of punctures rather than striae; 

 interstices with some indistinct punctures, much concealed by 

 the pubescence. Pygidium also with coarse punctures con- 

 cealed by the pubescence. Ventral rings short. 

 Kobd, June 8, 1881 ; a single male example.
