Paratypes. — From the same locality (2 cTs, 3 9 s, Fig. 

 106); Havana, Cuba (1 d\ Baker, coll. Johnson); Bermuda 

 Islands (19, Kincaid, coll. Johnson). 



The females cannot be distinguished from those of ap- 

 pendipes, except by comparison, when they are seen to be 

 less shining and somewhat cinereous on ventral margins, 

 while that species has no trace of such, at least, the specimens 

 I have seen, which I consider belong there. The males are 

 readily distinguished by the large symmetrical hypopygium. 



48. P. albiseta n. sp. 



9 . Similar to insularis, but more robust and less shining. Front 

 very broad, depressed, and silvery to vertex. Antennae brown or 

 black, long acuminate, sericeous. Occiput subopake, much swollen 

 above. Mesonotum and scutellum subopake, brownish tinged ; meta- 

 notum, especially laterally, cinereous. Abdomen dull, hardly shining, 

 except apical segments, which are more or less cinereous laterally in 

 form of large spots ; first somewhat hoary, with lateral comb of long 

 ivhitish hairs ; black bristle-like hairs rather numerous^ especially 

 apically and laterally on fifth. Ovipositor rather slender, thickened at 

 its articulation with the elongo-globose base (Fig. 99); extending to 

 third segment. Legs rather stout; apices of femora, bases of tibiae 

 and tarsi, yellow; post-tarsi distinctly dilated; fore femora with two 

 long basal hairs beneath ; the other legs apparently not adorned ; 

 femoral spines not discernable. Wings hyaline. Length, 3.5 mm. ; 

 wings, 2.8 mm. 



Type. — Hamilton Parish, Bermuda Islands, May, 1909 

 (Fig. 99, S. Brown, A. N. S., No. 5030). 



Paratype. — Belleaire, Fla. (1 9 , Slosson, coll . Johnson). 



Distinguished by its robust build, dull, nearly shining ab- 

 domen, wide silvery front, and whitish comb on first seg- 

 ment. 



49. P. proximus n. sp. 



9 . Upper part of front shining, lower part, face, and lower occiput 

 silvery. Third antennal joint brownish, long silvery acuminate. Meso- 

 notum semi-opake brown pollinose, in certain aspects whitish ante- 

 riorly, with two silvery spots on anterior margin and one in each noto- 

 pleural depression ; a distinct dorso-central series of small bristles 

 which connect anteriorly with a lateral series running obliquely caudad 

 the humeral callus; scutellum subopake. Pleurae and metanotum 

 somewhat grayish ; halteres yellow. Abdomen semi-shining, mi- 

 nutely and weakly rugulose, clothed with short, distinct suberect 

 black hairs, which are very distinct on fifth segment ; lateral margins
