<3 . A black species, Avith the legs partly pale. Head dull, 

 closely and finely punctate, with dense long silvery pubescence ; 

 mandibles (except apically) , and palpi, stramineous ; f rons finely, 

 closely, and irregularly striate in the centre. Antennae with dense 

 short black pubescence; the scape 

 testaceous beneath. Thorax with 

 dense long silvery hairs, closely and 

 regularly punctate ; metathorax 

 more strongly punctate ; areola fully 

 twice as long as broad, truncate, of 

 equal width at both extremities and

HymtHoibosmina pilosella, Cum. striate, especially in the centre of 

 its broad apex. Abdomen black, with 



the four apical segments laterally, and the apices of the third and 

 fourth broadly above, ferruginous. Legs testaceous, with the 

 anterior femora rufescent and their coxae black ; hind legs black, 

 with the tibiae broadly rut'esceut centrally beneath and the calcaria 

 dark testaceous. Wings with the tegulae stramineous, stigma and 

 nervures black. 

 Length 8 millim. 



The black markings on the legs are variable in extent, and the 

 intermediate legs are somewhat darker than the front ones. This 

 species differs from H. mandibularis in having the petiolar area 

 apically broad, the areola not basally acuminate, and the hind 

 femora and tibiae, except the latter centrally beneath, black.

 a small and elongately petiolate areolet.
