564 Mr. Watkrhouse's descrijitions of 



{i\nca\ joint not ([uite twice as long as the previous joint, tri- 

 angular, emargiuate at the apex, the outer angle rather more 

 prominent than the inner one. Apical joint of the labial palpi 

 subparallel, truncate, or vei'y shghtly emarginate at the apex. 

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

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

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

 length as the fourth, but with the internal angle much more 

 angularly produced. Prosternum produced posteriorly betAveen 

 the coxas, gradually acuminate. Mesosternum horizontal, a 

 little longer than broad, with an impression in front for the 

 reception of the prosternal process. Abdomen with five seg- 

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

 apical segment semicircular. Legs slender ; tarsi long and 

 slender, the second, third and fourth joints subequal, about 

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

 l)asal joints together; claws a little dilated at their base. Body 

 below finely pilose. 



Very close to JEubria, but without impressed lines on the 

 elytra, with more simple palpi, &c. 



Schinostethus nigricvriiis, n. sp, 



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

 tennis uigris, thorace basi subtiliter serrato-marginata. Long. 



2 hn. 



Very convex, rusty yellowish-red. Antenna; black, excei)t 

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

 pressed line. Thorax very convex, semicircular in outline, 

 truncate in front, when seen from above, twice as broad at the 

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

 pression at the base, 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 whole basal margin is very 

 finely creuulate, and there is similar crenulation along the base 

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

 lateral tiiangie. Elytra broadest rather behind the middle, 

 together obtusely roimded at the apex, the lateral margins near 

 the shoiilder a little impressed above. The metathoracic epis- 

 terna are rather strongly and moderately thickly punctured. 

 All the underside of the insect is exceedingly finely pilose,
