504 Mr. Waterhouse's descriptions of 



apical joint not ((uite twice as long as the previons joint, tri- 

 angular, emarginate at the apex, the outer angle ratlier more 

 prominent than the inner one. Apical joint of the labial palj)! 

 su})pai-allel, truncate, or very slightly emarginate at the apex. 

 Basal joint of the antennae* obconic, the second round, the 

 third elongate, the fourth joint one-third shorter than the third, 

 broader at its apex, the following joints of about the same 

 length as the foiirth, but with, the internal angle miich more 

 angularly produced. Prosternum produced posteriorly between 

 the coxa3, gradually acuminate. Mesosternum horizontal, a 

 little longer than broad, Avith an impression in front for. the 

 reception of the prosternal procoss. Abdomen with five seg- 

 ments, the margins of the first four segments straight, the 

 apical segment seijiicircular. Legs slender ; tarsi long and 

 slender, the seconci^'i' third and fourth joints subequal, about 

 half the length of the first, the fifth joint as long as the three 

 basal joints together; claws a little dilated at their base. Body 

 below finely pilose. 



Very close to Euhria, but without impressed lines on the 

 elytra, Avith more simple jialpi, &c. 



Schinostethus nigrirorids, n. sp. 



Ferrugineus, supra rufo-ferrugineus, opacus, convexus; au- 

 tennis nigris, thorace basi subtiliter serrato-margiuata. Long. 

 2 lin. 



Very convex, rusty yelloAvish-red. Antenna^ black, except 

 the two basal joints. Forehead Avith a slight longitudinal im- 

 pressed line. Thorax very convex, semicircular in outline, 

 truncate in front, Avhen seen from aboA^e, tAvice as broad at the 

 base as in front; arcuate at the sides, with a blunt oblique im- 

 pression at the liase, on each side of the middle; the base is 

 nearly straight, only very slightly sinuate on each side ; the 

 angles are nearly right angles; the Avhole basal margin is very 

 finely crcnulate, and there is similar creuulation along the base 

 of the elytra and scutellum. The scutellum is nearly an equi- 

 lateral triangle. Elytra broadest rather behind the middle, 

 together obtusely rounded at the ajiex, the lateral margins near 

 the shoulder a little impressed aboA'e. The nietathoracic epis- 

 terna are rather strongly and moderately thickly punctured. 

 All the underside of the insect is exceedingly finely pilose.
