INSEGTA SAUNDERSIANA. 
Head, short, immersed in the thorax to the eyes, subperpendicularly 
(with the rostrum) deflexed when at rest, obliquely narrowed by the eyes 
towards the apex; pitchy, covered with a whitish pile, thicker and yellowish 
along the eyes, showing two longitudinal thin fuscous denuded lines. 
Eyes rather large, of a somewhat circular form, with the anterior part 
under the margin of the rostrum narrowly subquadrangularly emarginate; 
very finely reticulate, convex ; nearly two-thirds of their transverse diameter 
being on the upper side, with the anterior part more approximate, having 
the forehead in that part (apex) not half the width of the rostrum. 
Rostrum as wide as the head, very short, transverse, flat, covered with a 
white pile; sides widely rounded ; apex slightly emarginate; marginal 
ridge acutely angulated near the eye, which it does not reach, then perpen¬ 
dicularly directed downwards, margining the antennal groove, which is 
exactly placed under the upper margin, subtriangular, somewhat linearly 
produced beneath, but terminating very far from the base of the rostrum. 
Antennce shorter than the thorax, reaching slightly behind its base, very 
slender: 1st and 2nd joints proportionally much thicker, 1st obclavate, the 
longest, 2nd subglobular; 3rd to 5lh very slender, subcylindric, subequal, 
long in proportion to their slenderness, but not longer than the 2nd ; 6th 
to 8th much shorter and somewhat thicker, 6th subconic, 7th and 8th sub- 
globose, pitchy. Clava ample, subovate-acute, depressed, shorter than the 
funiculus, tomentose. 
Thorax cylindrico-conic, subtransverse, evidently shorter than broad; 
apex truncate and scarcely half the width of the base; sides nearly straight 
and dilated towards the angles of the posterior carina, then obliquely and 
shortly narrowed to the basal angles, which are acute; base slightly 
sinuate, scarcely produced in the middle; posterior carina nearly ap¬ 
proaching to the base, especially in the middle, where it is more produced, 
but not acutely, its lateral angles widely rounded, then running upwards 
it vanishes before reaching the middle of the sides; convex; slightly 
punctate-rugulose; pitchy, covered with a dark fuscous pile; adorned with 
ill-determined lines of a yellowish white pile: one in the middle extending 
from the apex, where it meets that of the head, and terminating in the 
middle of the thorax; another opposite, at the base, short, divaricated; 
three lateral, distant at the base, the two external obliquely directed 
towards the median, which they meet in the middle of the thorax, then 
running unitedly to the apex, meeting there the intra-ocular lines of the 
head ; all these lines are thick, nebulous at their obsoletely circumscribed
