648 REV. H. S. GORHAM ON THE [DeC. 20, 



Head deeply sunk in the prothorax, so that the eyes are half 

 hidden, crown punctured and uueveu ; epistonia transverse and punc- 

 tured ; labrum membranous, twice as wide as long ; eyes oblique 

 coarsely granulate. Antennae more than half as long as the body, 

 their third joint a liltle longer than the fourth, and this to the eighth 

 gradually diminishing in length, ninth and tenth obconic, terminal 

 joint triangular, obliquely truncate, as wide as long. Thorax 

 shining, disk even, moderately thickly and distinctly punctured, 

 front angles very acute, projecting as far as the base of the antennae 

 when the head is not exserted. Elytra very convex, and much 

 rounded on the sides ; viewed laterally the greatest convexity is at 

 one third from the base, so that they are gibbous, their margins are 

 reflexed but not expanded ; each has a yellow sj)ot at the base, which 

 has a deep notch behind, and the small humeral callus which invades 

 it in front is of the pitchy-black colour of the elytra, also a somewhat 

 arcuate transverse spot behind, notched on its front edge. 



The punctuation is thick and obsolete above, rather coarse and 

 deep on the body beneath. 



Mr. Lewis secured a considerable number of examples of this 

 insect. They were first met with on June li, on fungoid growth on 

 trees which had been broadly ringed ; they were then immature, but 

 a week later mature examples were abundant, and obtained by beating 

 the brushwood. 



Panamomus, Gorham. 



1. Panamomus lewisi, Gorh. Ent. Mo. Mag. ix. p. 207. 



Many examples were found by Mr. Lewis at Nagasaki in March 

 1881, also in April at Kumamoto, under dead leaves in sunny places in 

 spring, the original example in fungoid growth. 



The species was described from a unique example captured by 

 Mr. Lewis in the same locahty, Nagasaki, in 1866. 



2. Panamomus decoratus, n. sp. (Plate LIII. fig. 10.) 



Flavus, ferrugineo variegatus, fere impunctatus, prothorace maculis 



tribus, duahus lateralibus angulatishrunneis, una medianafusiformi 



nigra; ely iris per obsolete punciatis, suturajione medium, macu- 



lisque duabus in singulis, magnis subquadratis nigris; callo huiner- 



ali interdum nigrescente. Long. 2f millim.

The size and form of this new species are the same as those of 



P. lewisi, the punctuation especially of the thorax more ohsolete, in 



fact only very faint and sparse punctures can be seen on the elytra 



under a strong lens. The antennae, some marks on the head, the 



margins of the thorax and of the elytra, with the suture, and callus 



of the shoulder are all darker than the ground of the elytra. In 



some specimens the club of the antennae is infuscate, and in one the 



anterior spot on each elytron is fused with the sutural plagia, and the 



whole insect is darker, and the punctures of the elytra are distinct 



and are seen to form in places irregular series.
