622 FAUNA HAWAIIENSIS 



from the eye-margins and often difficult to see. Antennae filiform 12-jointed. 

 Mesonotum without furrows. Marginal vein of front wings shortish, shorter than the 

 postmarginal, which is well developed, rather longer than the stigmal, the latter knobbed 

 at the apex, very oblique or almost longitudinal in direction, originating about the middle 

 of the length of the wing ; marginal, submarginal and postmarginal veins with regular 

 series of bristles ; front wings shortly fringed, the cilia longest near the apex of the 

 dorsal margin, basal nervure not defined. Abdomen very wide at base adapted to the 

 propodeum, sessile, the second and third segments not differing greatly, or the latter 

 rather longer. 



( I ) Dyscritobaeus comitaits, sp. no v. 



Male black, with whitish pubescence, the scape of the antennae in front, the legs, 

 the whole of the second abdominal segment, the third at least on its basal portion 

 yellowish brown or testaceous. 



Head dull, appearing very densely punctate or shagreened, antennae with tlie 

 scape extended about as long as the whole insect, the pedicel subtriangular, about as 

 long as the first funicle joint, the latter and all the following not differing much in 

 appearance, appearing slightly longer than wide, apical joint acuminate and longest. 

 Thorax dull, closely punctate (under high powers of the microscope the sculpture is 

 seen to consist of punctures and a reticulation of fine lines) metathorax a little angulate 

 in the middle. Second and third abdominal segments longitudinally striate, the former 

 more strongly and distinctly than the latter. Length 75 mm. 



Hab. Oahu, Honolulu ; in company with the preceding, which it very closely 

 resembles superficially. 



Baeus Hal. 

 ( I ) Baeus persordidus, F.p. nov. 



Dark pitchy brown, the head almost black, the abdomen rather paler than the 

 thorax, legs infuscate or sordid yellow, paler than the body, hind tarsi yellow above, 

 the tips dark. 



Head much wider than the thorax, somewhat shining and smooth, very finely and 

 not closely punctured ; thorax and abdomen finely punctured and clothed with short 

 white hairs. Hind tibiae long, but not twice as long as the tarsi, basal joint of the 

 latter about equal to the three following together. Abdomen very strongly decurved, 

 in dorsal aspect the second segment forms nearly the whole visible surface. 



The antennae have an elongate ovate club, rather longer than all the funicle joints 

 and the pedicel together ; the latter is nearly as long as all the funicle joints, which are 

 very short, the first being the longest. Length (!?) "5 mm. 



Hab. Oahu ; about 2000 ft.
