Rhyncho'phorous Ooleoptera of Japan. 105 



most other respects extremely closely allied to D. 

 inornnbis, the front femora are, however, though dilated 

 and angular beneath, provided only with a very minute 

 tooth. The legs are red, but on their anterior aspects 

 are densely squamose. 



I have seen only two specimens of this elegant insect. 

 They were found in the Main island at Nikko and 

 Kashiwagi in June. It should be noticed that Mr. 

 Lewis found at Nikko a single immature individual of a 

 species of Phyllohmis that resembles JJ. mundus almost 

 exactly. 



o. Diallohius leivisi, u. sp. 



Niger, minus dense viridi-aureo squamosus, antennis pedibusque 

 rufis, illis clava nigricante ; femoribus omnibus maxime dentatis. 

 Long. 6^ mm. 



A very remarkable insect, of which only a single 

 specimen was found, it is a male; it differs greatly from 

 the other two species of the getius, and bears in fact a 

 relation to the first division of Phyllohius, similar to that 

 exhibited by D. mundus and trwrnatus to the second 

 division. Rostrum with the broad apical part very 

 definite, not squamose, feebly bicarinate before the eyes. 

 Scape of antenna nearly straight, broad at the extremity, 

 8th joint about as long as broad, club moderately long, 

 acuminate. Eyes moderately large, but little prominent, 

 encroaching somewhat on the front of the head. Thorax 

 rather large, much rounded at the sides, only a little 

 narrower in front than behind, sparingly covered with 

 brilliant, hair-like scales, which do not conceal the 

 sculpture, this consists of moderately coarse and close 

 punctures, with the interstices dull, owing to a minute 

 coriaceous sculpture. Elytra with rows of large punc- 

 tures, black and shining, with brilliant hair-like scales. 

 Legs very peculiar, the femora flat, with extremely large 

 triangular acute tooth ; tibite also compressed, so as to 

 exhibit an edge externally, the lower part of each rather 

 deeply emarginate, so that a sort of obtuse angle is 

 formed above the middle. Under surface, shining, black, 

 with very little clothing.
