304 Mr. D. Sharp's Contributions to the 



tennis pe(lil>us(|ue testaceis, elytris ol)liqiie fiisco-signatis ; 

 tliorace lateribiis rotiindatis, anterlus subito constrictis, 

 crebre pinictato, utrinquc longitudinaliter inipresso ; abdo- 

 mine latiusculo, minus distincte punctato. Long. corp. 

 2 liii. 



Antenna? pale yellow, of the ordinary Sf/nins structure, 

 about as long as head and thorax, slender ; 3rd joint much 

 longer than 2nd, 4 — 10 each shorter than its predecessor, 

 8 — 10 each slightly less slender than its predecessor, 10th 

 longer than broad, 11th rather stouter and a good deal 

 longer than lOtli. Labrum very large, the middle part 

 much produced, and the most projecting part truncate, 

 •without notch or teeth. ]\Iandibles moderately long, much 

 curved ; the left with two, the right with three teeth in the 

 middle. Head shining chestnut in colour, of the usual 

 Sunius form, but more gradually narrowed behind towards 

 the slender neck ; it is only sparuigly and indistinctly 

 punctured. Thorax nari'ower than the elytra, of a sin- 

 gular, somewhat flask-shaped, form ; the sides of the hinder 

 portion rounded, then abruptly narrowed in front of the 

 middle to make a slender neck ; the middle part is moi-e 

 elevated than the sides, so that there is the appearance of 

 a longitudinal depression on each side ; it is of a brownish 

 or chestnut colour and is rather coarsely punctured ; it has 

 a narrow impunctate line along the middle, and the lateral 

 portions are only indistinctly punctured. Elytra about as 

 long as thorax, rather shining, of a chestnut colour, each 

 with a darker obUque mark across the middle, and the 

 outer angle a little paler ; they are rather deeply, somewhat 

 coarsely and closely punctured. Hind body broad, chest- 

 nut-yellow, a little shining; the front portion of the two or 

 three basal segments rather distinctly punctured, the rest 

 scarcely visibly punctured. Legs very pale yellow ; the 

 first joint of the hind tarsus about as long as the other four 

 together. 



A single female of this extremely reniai'kuble s])ecies 

 was captured by Dr. Trail on the 5th Novi'nil)er, 1874; 

 but he has not transmitted to me the exact locality.
