shining, basal segment with distinct nearly even puncturation ; second somewhat 

 raised from the base, or at least very strongly convex ; beneath, raised above the 

 sulcature to a height rather greater than that of its basal portion, the sulcature itself 

 shining, with indistinct, nearly obsolete costae, the depression narrow but ver\' 

 distinct. 



Hab. Haleakala, Maui (5000 ft.). Two ? taken in the early part of 1894;

 Frons, pronotum, mesopleurae, tegulae plerumque, postscutellum, tibiaeque omnes 

 (plus minusve), eodem colore decorata. Mesonotum ( ? praecipue) remote puncta- 

 tum, minutissime etiam et dense punctulatum. Propodeum fortiter rugosum. Abdo-

 conicam fortiter elevatum. </ ? . Long. 8 — 9 mm. 



Black, with a median spot behind the antennae, another behind each eye, part 

 of the prothorax, a spot on the mesopleurae, the tegulae more or less, the post- 

 scutellum in front, the hind margin of the two basal abdominal segments, all the 

 tibiae more or less, of an orange-yellow colour. Mesonotum shining, the system of 

 larger punctures distinct but not coarse, and on the posterior half the puncturation 

 is sparse and irregular. In the % these punctures are finer than in the cf and much 

 more sparing, the system of minute punctures occupying the greater part of the 

 surface. Propodeum with coarse rugose sculpture. Abdomen shining, basal segment 

 very coarsely punctured towards the base ; second raised near the base into a conical 

 form ; beneath beyond the sulcature also raised to a height equal to, or slightly 

 greater than, that of its basal portion, the depression short and narrow, but distinct.
