OLIGOMYBMEX. 155 



anteriorly feebly emarginate. Frontal area narrowly triangular. 

 Club of antennae narrower than in 0. rothneyi, a little shorter 

 than the rest of the flagellum ; the scape extends at least up to 

 the posterior ocelli. Thorax much broader than the head ; meta- 

 notum rounded, with scarcely any appearance of tubercles. First 

 joint of the pedicel as in 0. asinus, but the petiole is shorter and 

 the node higher, very thick at base. Second node broader than 

 long. Antennae 9-jointed. 



" Front of the head densely striate, the remainder smooth and 

 shining. Back of the head, mesonotum and legs with strong 

 scattered punctures. Abdomen finely punctured. Pilosity short, 

 yellowish, abundant. Tibiae and scape with close-set hairs. 

 Of a yellowish or reddish brown, or of a brownish yellow. Top 

 of the head and an obscure band on each abdominal segment 

 brownish. Wings subhyaline, nervures a yellow-brown. 



d* . " Mandibles armed with 5 teeth. Head square, rather 

 broader than long ; antennae 13-jointed, scape shorter than the 

 2nd joint of the flagellum. First joint of the pedicel lower, less 

 concave in front and less petiolate than in 0. rothneyi. Abdomen 

 narrow, a little depressed ; genital valves smaller than in 0. roth- 

 neyi. Head striate and rather opaque, the rest shining and 

 punctured. Pilosity as in the 5 . Brown ; legs, antennae and 

 mandibles yellowish." (Forel.)

" $ . Mandibles shining, punctured, armed with 6 teeth. Head 

 and antennae identical with those of 0. raja, but the clypeus is not, 

 or scarcely at all, emarginate anteriorly in the middle, the scape 

 is not subclavate, and joints 2-4 of the antennae are broader 

 than long. Frontal area elongate. Thorax the width of the 

 head. Metariotum sub vertical, with two large obtuse teeth. First 

 node of the pedicel a little more squamiform than in 0. raja. 

 Second node trapeziform, constricted in front, Front of the 

 head striate save the middle of the clypeus which is smooth. The 

 rest of the head strongly punctured, the punctures deep, coarse, 

 abundant, but regularly spaced ; more feeble and scattered on 

 the abdomen, obsolete on the last segment. Between the 

 punctures the chitinous covering is smooth. Pilosity sparse 

 on the body, none on the scape of the antennae and the tibiae of 

 the legs. Pubescence sparse but distinct. "Wings moderate, 

 nervures dark brown : the radial cell closed. Black ; the mandibles, 

 antennae, legs excepting the coxae and abdomen of a reddish 

 yellow, nearly orange. Wings brownish." (Forel.)
