Mesitius mj rmecophilus sp. nov. 

 Female. — Length 3.2 mm. Black, shining, with sparse pale hairs; antenna; and 

 legs brown ; wings slightly infuscated. Head scarcely longer than wide, shining 

 black, with widely separated, but very distinct punctures; sparsely covered with 

 rather long whitish hairs. Antenna? 13-jointed, reaching to the tegulse, dark 

 ferruginous at base, fuscous at tip. Scape short and stout, scarcely equalling one- 

 half the greatest width of the head; pedicel more slender, but scarcely longer 

 than the first flagellu in joint. Following three joints quadrate, beyond which 

 they are very slightly longer than wide; apical joint slender, twice as long as 

 wide. Palpi and mandibles ferruginous, the latter dark at extreme tip. Prono- 

 tum sparsely and more finely punctured than the head, shining and with short 

 pale hairs, considerably longer than the mesonotum and scutellum taken together ; 

 tegulaa ferruginous. Mesonotum impunctate, with two fine longitudinal grooves, 

 which enlarge posteriorly and meet the two large foveas at the base of the scu- 

 tellum. Metanotum with a lateral and a median fine raised line and a fainter 

 one between these anteriorly which fades out behind ; delicately reticulate. Pos- 

 terior face with median and lateral raised lines very sharp, separated from the 

 metanotum by a similar line; very finely transversely rugoso-aciculate. Abdo- 

 men polished black, impunctured, pale hairy on posterior half. Sixth segment 

 ferruginous at tip. Wings hyaline, basal veins yellow ; stigma ami radius fus- 

 cous. Second basal cell without a backwardly directed vein. Marginal cell long 

 and widely open at tip. Legs rufopiceous.
