216 EMBRIK STRAND, 
lobe a little the longest. First recurrent nervure received at two 
thirds from the base of the second cubital cell, the second just 
beyond one third from the base of the third cubital cell. 
Shining black; the tegulae fuscous. Wings hyaline, very faintly 
tinged with yellow; nervures fuscous. 
Length 13—16 mm. 
2. Clypeus broadly and shallowly emarginate at the apex, with 
a median longitudinal carina; the mandibles falcate, rather blunt at 
the apex. Head more than half as broad again as long, very 
strongly rounded at the posterior angles, sparsely and rather finely 
punctured, the interantennal prominence bilobed, a deep frontal 
suleus reaching from between the antennae more than half way to 
the posterior margin of the head, the scape closely punctured above. 
Pronotum and scutellum closely punctured; the pronotum about half 
as broad as the head, fully half as broad again as long, slightly 
narrowed posteriorly and broadly emarginate on the posterior margin, 
not excavated; scutellum small and narrow. Median segment very 
minutely and closely punctured, a little longer than the pronotum, 
narrow at the base and a little higher than the scutellum, broadened 
posteriorly and obliquely truncate. Abdomen much broader than the 
thorax, the first segment narrow and concavely truncate at the base, 
broadened to the apex, rugose, with a few long hairs at the base 
of the truncation, the apical margin slightly raised with a broad 
transverse groove before it; second segment transversely rugose 
between two transverse carinae, the apical margin raised with a 
narrow groove before it; segments 3—5 very finely and closely 
punctured; pygidium longitudinally rugose, nearly as broad as long, 
the dorsal segment nearly as long as the ventral, but emarginate 
at the apex, the ventral plate rounded at the apex. Fifth ventral 
segment finely punctured. 
Dull black; the mandibles, except at the extreme apex, the 
anterior margin of the celypeus, the apex of the scape and the basal 
joints of the flagellum fusco-ferruginous; a broad curved band above 
the base of the antennae dull luteous yellow; spines of the tibiae 
and tarsi testaceous. 
Length 8—11 mm. 
Hab. Marcapata, Peru. 3000 ft. 
Described from 4 males and 2 females. 
This is a true Elaphroptera allied to E. atra GuEr., but the 
shape of the clypeus in the male is very different.
