small details. The form of the celypeus however distinguishes the 
species at a glance. It is not improbable that when the female is 
discovered this species may be found to be more nearly related to 
Scotaena than to Elaphroptera. 
Elaphroptera bogotana n. Sp. 
@. Mandibles bidentate, not elbowed, the outer tooth long and 
acute, the inner tooth short and blunt. Clypeus rather narrowly 
produced and shallowly emarginate at the apex, smooth and shining, 
shallowly punctured at the base. Head finely and closely punctured, 
with sparse cinereous pubescence; the interantennal prominence 
bilobed, divided by a very short longitudinal suleus; the antennae 
as long as the head, thorax and median segment combined, the 
apical joints strongly arcuate, the third joint of the flagellum dis- 
tinetly longer than the second. Pronotum sparsely punctured, shining, 
rather narrower than the head, the anterior margin slightly vaised. 
Mesonotum closely punctured, the parapsidal furrows very distinct; 
scutellum shining, sparsely and finely punctured, convex, very 
broadly rounded at the apex. Median segment sparsely and finely 
punctured, longer than broad, narrowed to the apex, with two short, 
shallow, longitudinal grooves from the apex, the sides clothed sparse- 
ly with whitish pubescencee Abdomen long and slender, narrowed 
at the base, sparsely punctured, the punctures large, the first seg- 
ment with a deep sulcus from the base to the middle; the seventh 
segment narrowly truncate at the apex, the hypopygium projecting 
very little beyond the dorsal segment, narrow and bluntly rounded 
at the apex. The maxillary palpi are rather long and slender, 
especially the apical joints, but not as much so as in Aelurus, 
The first recurrent nervure is received beyond the middle of the 
second cubital cell, the second just before one third from the base 
of the third cubital cell which is more than half as long again on 
the cubital as on the radial nervure. 
Black; the mandibles, except at the apex, the clypeus, except 
the extreme base and apex, the margins of the eyes broadly inter- 
rupted at the summit, the lobes of the interantennal prominence, a 
transverse line narrowly interrupted in the middle close to the pos- 
terior margin of the head, an elongate spot on the propleurae, an 
arched band narrowly interrupted in the middle on the pronotum 
Just touching the anterior margin near the middle, a small spot on
