244 PASSALID^. 



the anterior angles produced vertically as short points. The 

 sides of the ocular canthi are straight and 2:)arallel, and the 

 front angles are fairly sharp but not produced. The pronotum 

 is a little broader than it is long, completely margined, the 

 jDunciures confined to the marginal groove and lateral scars, 

 the front marginal groove very deep. The front angles are 

 rather blunt, the sides almost straight in front. The elytra are 

 rather short and broad, the stria? very deep and conspicuously 

 2:)unctured, the intervals very convex. The meiasternnm is 

 very smooth, excejit for a narrow, parallel-sided, finely rugose 

 lateral band, not deeply impressed, and the extreme anterior 

 angles, which also are finely rugose. The two basal abdominal 

 sternites are short and finely rugose, the three last stemites 

 broad and smooth. The lamellae composing the club of the 

 anteraia are not long. The front tihia bears an oval patch of 

 long stiff yellow hairs on its upper surface. 



Length, 20 to 27 mm. ; breadth, 7-5 to 10 mm.

Body long and narrow, very convex, almost devoid of hair 

 above and beneath, the legs with very scanty hair, the middle 

 tibia bearing two or three strong lateral spines. The median 

 process of the head extends to the front margin and is produced 

 obliquely forward and ui)ward as a narrow horn, grooved 

 above and bifurcated or blunt at the end. The front angles 

 of the pronotum are produced into short rounded lobes, and 

 the front margin has a deep sulcus on each side, the two sulci 

 not meeting as in Aulacocydus. There is also a deep median 

 sulcus. The antennal club is composed of three long lamellae 

 and the three ])receding joints bear very short supplementary 

 lol)es. The mandible is without a movable tooth, the tip is 

 acutely tridentate, and the outer edge is provided ^ith a 

 narrow rod-like ])rocess directed obliquely forward and upward 

 in corresi)ondenc(> with the cephalic horn. The outer lobe of
