thence abruptly constricted, the outline thence subsemicircular to the 

 apex, the constriction continued distinctly across the dorsum; sculp- 

 ture consisting of coarse punctures interspersed with low, polished 

 granules; each puncture bearing a conspicuous, fine, erect seta. 



Elytra slightly longer than broad (4.6:4.3), two-fifths longer than 

 the prothorax, broadest at about the basal third; base subtruncate; 

 lateral margins arcuately diverging from the base to apical third, 

 thence rapidly, arcuately converging to the apex ; striae shallow, bear- 

 ing large shallow punctures, broader than the intervals; intervals 

 marked by single rows of well spaced, low, polished granules and 

 single rows of erect, slender, very conspicuous, spikelike setae. 



Legs with the femora coarsely and densely punctate, the punctures 

 bearing distinct setae, the hind pair reaching almost to the apex of the 

 elytra, the tooth arising on the outer edge at one-third from the apex, 

 those on the fore pair largest ; tibiae slender, the hind pair two-thirds 

 as long as the femora, one-fifth as broad at the middle as long, the 

 punctate grooves between the carinae set with fine, erect setae similar 

 to those on the dorsum ; tarsi with dense, long hairs on the under sides 

 of the first three segments, the hair on segments 2 and 3 longer than 

 those segments, some of the hairs longer than both segments together. 



Sternum with the mesosternal receptacle terminating on a line 

 between the middles of the mesocoxae; metasternum transversely 

 concave, bearing large, shallow punctures, the sides very densely set 

 with small squamae forming a triangle from the middle of the coxa 

 forward to near the base of the elytra and back to the lateral junc- 

 tion of the metasternum and first ventrite, the shortest distance be- 

 tween the mid and hind coxae only one half the longitudinal diameter 

 of a metacoxa, the metacoxae separated by three times the breadth 

 of a coxa ; the suture between the venter and sternum broadly arcuate. 



Venter with the longitudinal diameter of the fovea greater than 

 the median length of the remainder of the abdomen plus the apices 

 of the elytra ; the distance between the anterior margin of the fovea 

 and the metasternum one third the median length of the metasternum, 

 the distance between the hind margin of the fovea and the third 

 ventrite less than the median length of the third ventrite; the floor 

 of the fovea not obviously punctate, bearing a few long, erect setae ; 

 ventrite 5 about twice as long as 3 plus 4, with a deep, arcuate depres- 

 sion in the anterior half. 



Length, 1.9 mm.; breadth, 1.1 mm. 



Type.— Ho\otyi:>e male (U.S.N.M. No. 53890) collected by C. F. 

 Baker on Mount Makiling, Luzon, Philippine Islands. Unfor- 

 tunately, I have seen only one specimen of this species. 



From the dorsal aspect this small insect resembles a nonsquamose 

 Aoalles, but it will easily be recognized when the lower surface is 

 examined.
