1470 COLEOPTERA 



Eyes broadly-oval, oblique. Antenna inserted at, rather than 

 before, the middle. Scape just reaching the eye. 



This is the finest known species. Its nearest allies are Nos. 2131 

 and 2391 : from these it is easily separated by looking at the tibiae. 



Length (rost. excl.), 3 ; breadth, If lines. 



Maketu, HunuaEange. One specimen. 



2548. E, firmus, n -s> Piceous, antennae and tarsi pitchy-red ; 

 squamosity infuscate-red, not coarse, depressed parts with pale 

 sappy matter. 



Host-rum elongate, tricarinate in front ; before the eyes with a 

 moderately-raised elongate crest or ridge, 011 the head there are two 

 small yet longitudinal ridges. Antenna clothed like those of E. 

 crassipes, second joint of the funiculus slightly longer than the first, 

 3-6 not longer than broad, somewhat bead-like, seventh larger 

 than sixth. Thorax very slightly longer than broad, its sides slightly 

 curved, not contracted anteriorly, its coarse irregular punctures 

 concealed ; there are three distinct, longitudinal, squamose eleva- 

 tions, those near the sides are oblique and reach the base, the 

 central extends to the basal depression, which, at each side, is 

 bordered with squamae. Elytra oblong, their sides not obviously 

 curved, of irregular outline, owing to the nodosities or patches of 

 squamosity, the middle of the base deeply emarginate and depressed, 

 the shoulders very little wider than the base of the thorax ; the 

 sutural rows of coarse punctures are regular, the others are not, the 

 declivity is almost punctate-striate ; near each side, at the base, 

 there are three elongate, squamose ridges, the central is the longest 

 but least elevated at the base; behind the middle there are two 

 elevations directed obliquely backwards from the suture, each con- 

 sisting of two parts ; on top of the posterior declivity there are four 

 tufts, the inner two much smaller than the outer, there is a larger 

 one lower down on each side ; the squamosity for the most part is 

 disposed longitudinally, most evidently so along the suture, there 

 are a few minute black tubercles above. Legs stout, densely clothed. 



Underside: Rostrum not carinate. Process of mesosternum not 

 raised. Abdomen: Second segment more convex than the first, with 

 a large depression along its frontal suture, the apical supplementary 

 segment scooped out. 



Eyes broadly-oval, oblique. Antenna inserted just before the 

 middle of the rostrum. 



Length (rost. excl.), 3J; breadth, If lines. 



Maketu. One. 



VAR. The oblique elevation on the middle of the elytra not 

 duplicate, but there is a smaller one near each side directed longi- 

 tudinally. 



Lithocia. 



Nov. gen. 



This genus is most nearly related to PJirijnixus, from which it 

 differs as follows :
