Form similar to Anasa., but broader, oval. Head two-thirds the 
length of the thorax, subconico-cylindrical, the upper surface gently 
curving towards the apex; the tyius defined almost to the base of the 
head, its apical carina perpendicular in front; juga produced beyond 
the tyius each side in a conical point; antennge prismatic, granulose, 
each of the three sides carinated upon the edge, the basal joint curved, 
thick, narrowed at base, the second and third joints subequal, the lat¬ 
ter with a minute tooth at the apex exteriorly, between it and the 
fourth is a minute, inserted joint, 4th joint fusiform. Eyes globose, 
situated a little nearer to the base of the head than to the scapus; genae 
emarginated beneath at the middle of the bucculae; bucculae rather 
more than one-third the length of the basal joint of the rostrum, broad, 
obliquely truncated in front, rounded and acute behind; rostrum reach¬ 
ing upon the abdomen, basal joint very thick, cylindrical, a little longer 
than the head, the remaining joints flattened, the seeond a little the 
longest, the third scarcely half the length of the fourth, the fourth 
about two-thirds the length of the second; labrum almost as long as 
the basal joint. Thorax subhexagonal, the latero-posterior sides but 
bluntly defined, forming a very obtuse angle with the posterior mar¬ 
gin ; all the margins, excepting the anterior one, carinately elevated, 
the lateral margins broadly elevated, anterior angles with a small tooth 
each side of the head, the anterior margin produced over the head so 
as to form a collar-like sheath which fits the head neatly; humeral 
angles not prominent, broadly rounded, and surrounded by the margi¬
