1435. Didymocantha clavipes, n. sp.—Elongate, sub-depressed, 
moderately shining, rufo-castaneous, femora dilute, tarsi and an- 
tennee rufescent. 
Flead punctate in front, the occiput with short smooth raised 
lines, the intervals densely and minutely sculptured, its yellow 
pubescence thickest near the eyes. Pvothorax as long as broad, 
slightly convex, obtusely rounded laterally, narrowest in front, 
base bi-sinuate ; the dorsal line smooth, a broad space on each 
side of it coarsely punctured, the sides a little uneven, destitute 
of tubercles, and, with the exception of a few large punctiform 
impressions, not sculptured, but densely pubescent, the coarser 
yellow hairs are confined to the dorsum. Scutellum densely 
pubescent. /ytra broader than thorax, near the base trans- 
versely punctate-rugose, from thence the punctation becomes 
finer and less rugose, so that towards the apices it is nearly obso- 
lete; they bear short, decumbent, coarse pallid hairs. Legs 
pubescent, femora strongly clavate, zd. est., nearly straight below 
but arched above. Aztenne@ as long as the body, their 4th joint 
shorter than 3rd, the latter but little shorter than 5th. 
May be readily identified by the absence of thoracic tubercles, 
and the strongly inflated thighs. 
Length, 534 ; breadth, 1% lines. 
One example in my own collection ; exact locality unknown.

minal joint of the maxillary nearly twice as long as the penulti-:

line with the inner margin of the eyes, pubescent, I1-articulate ; 
basal joint stout, not much clavate, 2nd minute, 3rd and 4th 
equal, each a little longer than the Ist, joints 5-7 longest and

body. Prothorax sub-cylindrical, contracted near the apex, base 
emarginate, the sides dilated just behind the middle and armed 
with a strong acute spine, two other equally stout, erect spines 
are placed on the disc. Scutellum transverse, rounded behind,
