342 ]\Ii\ D. Sharp's Cinitributions to the 



emaroinato, liiiea verticali bene discreta; protliorace elou- 

 gato, basin versus angustato. Long. corp. 2J lin. 



]\Ias latet. 



Fern. : alxlominc segmcnto 7" ventrali slmplice. 



Very closely allied to P. simplex, but the vertex is more 

 emarginate, so that the fine line which bounds the vertex 

 is not so straight ; .the insect is also rather less slender, the 

 thorax is l)roadcr in pro]iortion to its length, and has the 

 sides a little rounded and the central space more distinct, 

 and the pubescence of the hind body is more conspicuous. 



Ega ; a single female individual, -which is a little imma- 

 ture. 



3. Palnminus modcstus, n. sp. Fcn-uglneus, antennis, 

 palpis, pedibnsrpie pallide tcstaceis, illis elongatis ; thorace 

 sat elongato, latcribus rotundatis, basin versus minus an- 

 gustato. Long. Corp. 2g lin. 



Mas : abdomine segmento 7" ventrali producto, a})ice

Fem. latet. 



Antennae -white, slender and verv eloni^-ate, much longer 

 than head and thorax. Palpi with terminal joint very 

 large. Head rather small, the vertex almost straight; the 

 punctuation similar to that of P. suiij)le.x. Thorax about 

 as long as broad, a good deal rounded at the sides but not 

 greatly narrowed behind ; its surface coarsely and irregu- 

 larly, not densely punctured, the central space rather con- 

 spicuous behind. Elytra broader than the thorax, and 

 nearly one and a half times as long; their punctuation 

 rather coarse, but not dense. Hind body with the pubes- 

 cence long and conspicuous; the sculpture of the four basal 

 segments coarse, the two apical ones smooth. Legs white ; 

 hind tarsi elongate and slender. 



In the male the middle ])ortion of the ventral plate of 

 the 7th segment of the hind body is a good deal produced ; 

 the hind margin is rounded, and has a small, sharply 

 defined notch in the middle. 



Ega ; a single male. 



1'hough this species greatly resembles P. simplex, it 

 may be very readily distinguished by the male characters ; 

 though the female is unknowu to me, the different form of 

 the thorax from that of 1\ siinj/lcx will no doubt h^^ com- 

 mon to it and the male. The species bears a still greater 

 resemblance to P. longicornis, but the head is smaller, the 

 vertex less emarginato,and the thorax le.ss narrowed behind.
