"more or less developed" in the i4th line from the top of 

 the page should be omitted. 



P. globosus n. sp. 



Allied to P. aequus Cress., but the antennae are black; legs black 

 except knees and extremities of tibiae; ovipositor short, yellow, with 

 black, globose base. Front subopake, shining only at vertex, becoming 

 silvery towards antennae, with an evident, narrow, median shining 

 stripe; antennae abruptly long acuminate (Fig. 12) (i). Mesonotum 

 subopake, brown, lateral margins cinereous, anterior angles more sil- 

 very; scutellum cinereous; humeri yellowish; pleurae and metanotum 

 cinereous ; halteres brown. Abdomen elongate, subparallel laterally, 

 subopake, brownish with lateral angles of segments cinereous; first 

 segment with small lateral comb of black bristles; fifth and sixth sub- 

 equal, longer than fourth. Ovipositor short, reaching only to apex of 

 fourth, yellow, abruptly attenuating from a rather small shining black, 

 globose base (similar to Fig. 81). Nearly all tarsi yellow. Wings hya- 

 line, stigma equalling 4th section, fifth, one and a half times fourth; 

 fourth vein simple. Length 3 mm., wing 4 mm. 



Type Locality. Buttomvoods, R. I. 



Type. Female, collected July 25, 1911. In the collection 

 of the Boston Society of Natural History. 



P. fuscus Loew. 



In the I4th line from the top of the page (3) of my de- 

 scription, the "humeri" should be black instead of "yellow," 

 thus reading, humeri black and halteres yellow. 



P. biscaynei n. sp. 



Antennas with third joint yellow, long white acuminate; humeri 

 black; abdomen subopake to opake, densely cinereous laterally; ovi- 

 positor extending to base of abdomen, yellow, gradually tapering from 

 an elongate globose base; 6th segment of abdomen slightly longer than 

 5th; legs entirely yellow; stigma colored, equalling following section 

 and shorter than 5th section ; fourth vein forked. 



Seemingly allied to P. brevis Cress., but differing from the descrip- 

 tion of that species (I have not the type before me) as follows: Front 

 mostly shining black, only silvery a little above the antennae, con- 

 stricted towards vertex; occiput normal; knob of halteres entirely 

 yellow. Abdomen subopake to opake ; first, lateral and ventral mar- 

 gins of 2-4, 5th except a median stripe, and entire 6th segments, densely 

 cinereous, the dark portions subopake, brown pruinose ; 5th segment
