Since the typical form of O. tempiferus was incompletely 

 described, I feel justified in describing fully the variety fnacio. 



Female. — Head (fig. 15, A) in front view broadly elliptical, slightly 

 wider than high ; seen from above, transverse, two and one-half times 

 as wide as long, as wide as thorax; occipital margin slightly 

 curved inward. Vertex and cheeks margined throughout by a sharp 

 uniform carina. Cheek wide, in profile as wide as upper half of eye, 

 gradually narrowed from middle to mandibular condyle, where it 

 forms a narrow groove. Inner orbits at vertex one and one-fifth times 

 as far apart as at clypeus. Upper half of frons little swollen, with 

 distinct but shallow median saddlelike depression between anterior 

 ocellus and interantennal ridge. Ocelli in a flattened triangle, poste-

rior pair twice as far apart as from the anterior, slightly less than 

 from eyes, about as far from eyes as from occipital margin. Inter- 

 ocellar area flat with median longitudinal linear groove. Vertex medi- 

 ally with two minute hairy foveae, close together and slightly nearer 

 occipital margin than posterior ocelli. Antennae twice as far apart 

 as from eyes; ridge between them low. Clypeus very broadly pear- 

 shaped, scarcely wider than high, disk slightly flattened, upper part 

 moderately convex, with weak preapical concavity; lower subocular 

 portion about as long as interocular part ; truncate apex about one- 

 fifth greatest width of clypeus, very slightly incurved with short but 

 sharp, toothlike lateral edges. Antennae rather long and slender, 

 flagellum scarcely swollen apically; scape slender, distinctly curved,
