EUBULUS. 563 
the interstices punctulate and faintly granulate, 3,5, 7,and 9 costate. Beneath coarsely punctate. Legs 
moderately long, the femora unidentate. 
Length 43-42, breadth 2-23 millim. (¢ @.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens. Smaller than L. lamellatus, the head without a transverse frontal 
carina, the prothorax relatively narrower and less coarsely punctate, the rostrum not 
so stout. 
36. Eubulus bihamatus, sp.n. (Tab. XXVII. figg. 30, 30a, 3.) 
Broad, robust, subrhomboidal, black ; mottled above with a dense clothing of intermixed reddish-brown, whitish, 
and black scales, the whitish and black scales here and there condensed into small spots on the elytra, and 
also set with very short, scattered, suberect, setiform scales; the vestiture of the under surface reddish- 
brown intermixed with whitish. Head flattened in front, asperato-punctate, obliquely carinate on each side 
above the eyes and sometimes bicarinate between them, the oblique carine not meeting in an acute angle 
at the middle ; rostrum stout, strongly arcuate, rugosely punctate and carinate, the punctuation becoming 
more scattered towards the tip, the apical half smoother in the 9, the antenne inserted behind the 
middle, joint 2 of the funiculus longer than 1 or 3. Prothorax strongly transverse, constricted in front, 
the sides rapidly, arcuately converging from the base; densely punctate, sparsely granulate, and sharply 
arcuato-carinate, the carina becoming lower towards the apex and not continued on to the head. Elytra 
subcordate ; seriate-punctate, the interstices 3, 5, 7, and 9 sharply costate, the others feebly granulate, 
the ridge on 3 curved inwards at the base, the suture narrowly raised. Beneath coarsely, densely 
punctate. Prosternal ridges in the ¢ armed in front with a rather long, feebly curved, truncate, hook- 
like process. Metasternum angularly raised on each side above the posterior coxw. Femora bidentate. 
Anterior tibie: slightly narrowed towards the apex. Penis-sheath broad. 
Length 83-12, breadth 44-64 millim. (¢ @.) 
Hab. Mexico, Tapachula (Hoge); Guatemata, El Reposo and Paraiso (Champion). 
Many specimens, all from the “tierra caliente” of the Pacific slope. Very like 
E. aspericollis, but with the oblique carine on the head not so prominent and not 
united into a \-shaped ridge, the median carina of the prothorax not extending on to 
the head and becoming lower towards the apex, the prosternal ridges armed with a 
stout hook in front in the male. In repose these hooks meet the apex of the antennal 
scape, and are apparently used to guide the antenne into the rostral grooves.

Extremely like £. aspericollis, but with the prothorax sparsely granulate and less 
setose, the vestiture of the prothorax and elytra brown, variegated (when fresh) with 
small ochreous spots, the cinereous patches wanting, the fifth ventral segment of the
