(ConocerHALUS). By SamureL H. ScuppER,. 
91. Conocephalus hamatus. A stout species of moderate 
size, brown, the teemina faintly flecked with fuscous dots, especially 
along the edges. Fastigium above flat, triangular, regularly tapering, 
pointed, advanced in front of the eyes as far as the narrowest space 
between the eyes, and like the rest of the summit of the head scabrous; 
the apex bent downward in the form of a minute, delicate, pointed 
hook ; a similar, stouter, but delicate pendant to the lower base of the 
fastigium, the middle line between them carinate, either side flat and 
very scabrous. Pronotum scabrous, the disk scarcely enlarging pos- 
teriorly, the lateral lobes roundly deflected, giving the thorax a 
stout appearance. Teomina tolerably broad, and nearly equal, the 
extremity obliquely docked, the inferior (inner) edge slightly up- 
turned at tip, and rounded. Femora scabrous, the middle and hind 
pair and apical half of fore pair furnished beneath with pretty stout 
and not.infrequent spines; hind legs very short, the tibie being less 
than half as long as the tegmina. Ovipositor comparatively short, not 
reaching so far back as the tegmina, and only slightly longer than 
the hind tibize. 
Leneth of body, 33.5 mm.; of fastigium beyond front edge of eyes, 
3 mm.; of pronotal disk, 8.75 mm.; of tegmina, 43 mm.; of hind 
tibiz, 18 mm.; of ovipositor, 21.5 mm. 1 ¢. Guatemala, Van 
Patten. 
This species closely resembles C. uncinatus Harr., but has a shorter 
fastigium. 
92. Conocephalus aduncus. A small and slender species, 
ereen' or brown, the tegmina sometimes with a very few distant 
fuscous dots. Fastigium of moderate size, arched above the plane of 
the head, the surface slightly flattened, and a little scabrous, enlarged 
a little beyond the base, and beyond the tumescence tapering rapidly, 
the extremity produced into a minute, pointed, decurved, glistening, 
eastaneous hook; the base of the fastigium below is armed as in C. 
hamatus, but lacks the median carina; the length of the fastigium be- 
yond the front of the flattened eyes is scarcely more than equal to 
the narrowest space between them. Pronotum minutely and pro- 
fusely punctate, the disk beyond the short anterior lobe regularly en- 
larging, gently in the 2, considerably in the ¢ ; the lateral carine 
Lovo) 
are rather sharply angled and the deflected lobes expand consider-
