210 ON NEW COLEOPTERA FROM JAPAN. [Feb. 17, 



Phytodecta rufipes, De Geer. 



Taking into consideration the great variability of our European 

 species of Gonioctena, the synonymy of which in regard to several 

 described species is not at all cleared up at present, I have referred 

 the specimens obtained at Nikko to the present species, although 

 there are perhaps sufficient differences present to justify its separation. 

 All the specimens before me are much smaller than those obtained 

 at Hakodate and noticed and named by Mr. Baly in the Transactions 

 of 1873 ; the clytral spots are obscure (although placed as in P. 

 rvfipes), in one instance confluent and occupying nearly the entire 

 disk ; but the short antennae, punctuation of the elytra, and the 

 entirely rufous legs agree with P. rufipes. As, however, all the six 

 specimens are of half the size only of the last-named species, it is not 

 improbable that they really represent another species. 



Phytodecta gracilicornis ?, Kraatz. 



The description of one of the varieties with confluent spots, given 

 by the author (Deutsche entom. Zeitschr, 18/9), agrees so well with 

 the three specimens contained in this collection that T must refer 

 them to the present species. The antennge are slender and the 

 joints are of the same comparative length ; but the entire head, thorax, 

 underside, and legs are black, the disk of the thorax is very finely 

 punctured, in some sfiecimens almost imjmnctatp, the sides are very 

 strongly punctured (Dr. Kraatz says nothing about the sculpture 

 of the thorax). The elytra have the interstices either very finely 

 punctured or impunctate, and the posterior spots are in two specimens 

 confluent, forming two irregular concave-shaped bands, the posterior 

 of which includes a small fulvous spot near the apex (as given in the 

 author's description). The characteristic feature ©f this species, in 

 regard to the markings of the elytra, seems to be the large sutural 

 spot common to both elytra which is placed below the middle and is 

 either separated or connected with the lateral spots. I have no 

 doubt that the Japan specimens are but slight varieties of Kraatz's 

 species, although an examination of the type alone can settle the 

 point. 



Phytodecta nigroplagiata, Baly. 



This species seems to me extremely closely allied to P. viminalis 

 or P. rubripes, with which it agrees entirely in the pattern of the 

 elytra ; the latter are, however, closely and distinctly punctured at the 

 interstices, much more so than in the allied species, which will help 

 to distinguish P. nigroplagiata. The specimens contained in Mr. 

 Lewis's collection have all black undersides and legs as well as the 

 five last joints of the antennse, of which Mr. Baly makes no mention. 

 There is also a black transverse band placed at the base of the thorax, 

 also unnoticed in Mr. Baly's description. 



Genus Gastrolina, Baly. 

 Gastrolina japana, n. sp. (Plate XI. fig. 12.) 

 Oblong, subdepressed, greenish black ; thorax and legs fulvous.
