 forms a transition to the genus Agathyrna Stal. 



Homalocolpura sorbax sp. nov. 



Oblong-ovate, shiny beneath (including the ventral glandular 

 spots), much less so above, black, corium fuscous-black, ante- 

 rior end of bucculffi, apex of scutellum, a small spot near middle 

 of apical margin of corium, and apical margin of fourth and 

 fifth ventral segments luteous, an interiorly abbreviated apical 

 fascia to the connexival areas above and beneath fulvous, 

 membrane black, orificia brownish; antennae fuscous-black, 

 third joint a little paler, base of third and the whole fourth 

 joint luteous; rostrum luteous; legs piceous-black, coxae and 

 tibise somewhat paler, trochanters, base of femora, and the 

 tarsi luteous, last joint of the latter infuscated; moderately 

 densely punctate, excluding head, the subapical pronotal trans- 

 verse callosity, and the connexivum above and beneath; the 

 whole body clothed with a very short upright pile visible only 

 if the insect is viewed in profile, but somewhat longer and 

 semierect on the venter, the short hairs on the postocular 

 tubercles and on the lateral margins of the pronotum stiffer and 

 visible also from above. Head one-half longer than broad 

 and almost as long as pronotum, transversely and longitudinally 

 convex, sparsely and finely punctate, slightly widening from 

 eyes to apex of antenniferous tubercles, this distance shorter 

 than anteantennal part of head, eyes larger and more prominent 

 than the postocular tubercles, antennae half the length of the 

 body, rather slender, first joint about half the length of head, 

 passing apex of head by less than half its length, second joint 

 a little longer than first and a little shorter than third, fourth 

 longer than third, subcylindrical, rostrum reaching a little be- 

 yond apex of abdomen. Pronotum a little declivous, about one- 

 half broader than long, at apex a little more than half the basal 

 width, near apex with a rather strongly convex, anteriorly almost 

 perpendicular, transverse callosity almost reaching the lateral 

 margins, terminated behind by a transverse impression and in 

 the middle of its posterior half subquadrately impressed, the 

 apical angles right-angled, projecting a little forward, the 

 lateral margins straight, very narrowly carinate, the basal 

 margin somewhat sinuated in front of the scutellum, which 

 is slightly convex in its basal half. Elytra of female reaching 

 base of first genital segment. Abdomen with the apical angles 

 of the fifth segment very slightly prominent, venter deeply 

 grooved from its base to apex of fourth segment, basal plica of
