DESCRIPTIONS OF TWO NEW PSELAPRIDM 



FOUND BY MR. J. J. WALKER IN AUSTRALIA AND CHINA. 



BY D. SHARP, M.A., F.R.S., &c. 



Mr. J. J. "Walker (whose entomological letters from H. M. S. 

 "Penguin" have so much interested the readers of this Magazine) 

 has sent me two specimens of CoJeoptera of the Family Psclaphidw ; 

 each of them proves to be the representative of a new genus. 



EULASINUS, n. g, {Tyrini, Eaffray). 



The insect for which this new generic name is proposed comes 

 very close to the genera Pselaphodes, Lasinus and Lahomimus, especially 

 the latter, from which, however, it can no doubt be very readily dis- 

 tinguished by the shorter 1st dorsal segment. Lahomimus was cha- 

 racterized by me from a single example, and that specimen is still all 

 that is known of the genus ; I described the palpi as angulate 

 externally, but I did not note whether there was any armature on the 

 prominences as there is in Eulasinus. The structure of the palpi 

 sufficiently distinguishes Ealasinus from Pselapliodes and Lasinus, to 

 both of which it is extremely similar in appearance. The 1st joint 

 of the palpus I am unable to see ; the 2nd joint is rather strongly 

 curved, the length being three or four times the greatest width, which 

 is at the apex, and at the outer side of this broadest part there is a 

 slight prominence armed with numerous excessively short setae ; 3rd 

 joint rather longer than broad, a little swollen and angular externally, 

 the prominent part armed with short setae ; 4th joint slender, elongate 

 oval, at one-third of the length from the base bearing externally a 

 feeble prominence, armed, like the prominent places on the preceding 

 joints, with short setae ; apex terminating in a transparent seta, quite 

 half as long as the diameter of the broadest part of the joint, and 

 bearing at the extremity an excessively minute terminal articulation. 



Eulasinus Walkeri, n. sp. 



Elongatus, puhescens, rufus, capite thorace antennisque rufo-ohscuris, 

 antennis p)Gdihusqiie elongatis ; capite thoraceque dense 7mgoso-sculpturatis, 

 singulo minutissime trifoveolato, thorace disco prominulo, tenuiter canaliculato. 



Long., 3 mm. 



$. Extremely similar to Lasinus spinosns, hut slightly smaller, and with the 

 front of the head shorter. Basal joint of antennae about as long as the three 

 following joints together, 2nd to 4th nearly similar to one another, each about as 

 long as broad, 5th and 6th each a little longer, 7th slightly shorter than 6th, a little 

 truncate on its inner face at the apex, 8th smaller, quadrate, 9th greatly dilated,
