10. Gyrophcena hoops, n. sp. liufo-testacea, nitida, 

 capite, elytris (humeris exceptis) abdomineque ante apiceni 

 nigricantibus ; oculis maximis ; capite thoraceque fere im- 

 punctatis; elytris abdomineque parce punctatis, pubes- 

 centia sparsa distincta. Long. corp. \\ lin. 



Antenna rather slender and moderately long, yellow ; 

 3rd joint more slender and distinctly shorter than the 

 2nd; 4th joint only a little smaller than the 5th; 5 — 10 

 only differing slightly from one another in width and 

 scarcely at all in length, the 5th about as long as 

 broad, the 10th a little transverse; 11th moderately 

 long, pointed. Head blackish, the eyes exceedingly 

 large and convex, occupying the whole side of the 

 head, coarsely facetted ; the space between them is quite 

 parallel-sided, shining, and almost impunctate. Thorax 

 very strongly transverse, more than twice as broad as 

 long, slightly narrowed behind, the base rounded; it is 

 of a shining-yellomsh colour, and is almost impunctate. 

 Elytra a good deal longer than the thorax, shining, black- 

 ish, with the humeral angles yellow, with a veiy few, fine, 

 setigerous punctures. Hind body yellow, with the penul- 

 timate segments blackish, the segments very finely and 

 sjminngly punctured, and also sparingly pubescent. Legs 

 clear yellow. 



In the male the elytra bear each near their hind margin 

 two tubercles, one near each angle ; the dorsal plate of 

 the 6th gegment of the hind body bears in the middle, at 

 the base, an oblong, large, shallow impression ; the hind 

 margin of the following segment exhibits an obtuse, 

 tubercle-like projection in the middle, and on each side 

 a very short spine.
