Allied to Poropterus, but the three intermediate segments 

 of the abdomen equal or almost so, and with the sutures of 

 the club oblique. Hexymus, to which it is also allied, has 

 distinct metathoracic episterna. 



Illidgea 16-tubehculata, n. sp. 



Black, subopaque, antennae and claws almost black. 

 Upper-surface rather sparsely clothed with distinct reddish- 

 brown adpressed scales, becoming more numerous and sub- 

 fasciculate on tubercles; those of the two anterior and of two 

 of the median prothoracic tubercles sooty; legs rather densely 

 squamose, on the femora sooty and brown scales intermingled, 

 on apex of femora and on the tibiae the scales are almost 

 entirely sooty. 



Head large, base depressed, indistinctly punctate ; ocular 

 fovea large. Sculpture of rostrum concealed by clothing but 

 evidently coarsely punctate. Scape noticeably shorter than 

 f unicle ; first joint of the latter longer and stouter than second, 

 third and fifth subglobular, sixth and especially the seventh 

 strongly transverse. Prothorax about as long as wide, sides 

 rounded, base narrowly depressed; each side of apex with a 

 small fasciculate tubercle, four tubercles across middle, the 

 lateral ones small, the median ones large, rounded, and almost 

 double; along middle an opaque median carina, indistinctly 

 terminated in front, but posteriorly forming a distinct scutellar 

 lobe. Scutellum longer than wide. Elytra scarcely wider than 

 prothorax, and not twice as long; shoulders excavated to re- 

 ceive the posterior angles of the prothorax; with two trans- 

 verse series consisting of four large rounded tubercles, the first 

 at about one-fourth from base, the second at summit of pos- 

 terior declivity, a small tubercle on each side just below sum- 

 mit; with a number of mixed, small, and moderately large, 

 distant punctures, becoming very small posteriorly and larger 

 and seriately arranged on the sides. Metasternum and abdo- 

 men with small sparse punctures, the apical segment, however, 

 densely punctate. Posterior femora passing elytra for about 

 one-third their length. Length, 9 mm.; rostrum, 3 mm.; 

 width, 4 mm. ; depth, 4 mm.

The clothing of the specimen described appears to be in 

 perfect preservation, it is dense only on the scutellum, 

 tubercles, legs, and apical segment of abdomen. The tubercles 

 in the middle of the prothorax are impressed in the middle so 

 that they appear to be double; this appearance is enhanced 

 by the clothing of the anterior portion being darker than that
