This is smaller than 0. concolor and may he at once distinguished 

 from that species, by the apical segments of the abdomen being fus- 

 cous. It is very closely allied to 0. cubensis, but slightly smaller, with 

 the abdomen shorter and not so slender, and the membraneous spot 

 nearest the tip of the first suhmarginal cell is very small and indistinct.

Collection. — Ent. Soc. Philad. One specimen. 



This species is closely related to 0. flavus, but is longer and more 

 slender, and at once distinguished by the two very distinct membra- 

 neous spots in the first submarginal cell. For the only specimen that 

 I have seen of this species, the Society is indebted to the kindness of 

 Baron R. Osten Sacken. 



Genus PANISCUS, Grav. 

 Paniscus subfuscus. n. sp. 



Dull rufo-fuscous, legs and antennae paler; basal segments of abdomen pice- 

 ous ; wings hyaline. 



Female. — Dull rufo-fuscous, opaque ; clypeus pale, pubescent ; an- 

 tenna as long as the body, slender, dull fulvous, slightly dusky at tips. 

 Thorax with the dorsal lines deeply impressed; scutellum prominent, 

 carinated on each side; metathorax minutely sculptured, incised at 

 base, with a small acute tubercle on each side behind. Wings hyaline; 

 nervures fuscous, stigma testaceous ; areolet small, subpetiolated, oblique. 

 Legs pale fuscous, the femora slightly dusky. Abdomen stout, arcu- 

 ated, subcompressecl, clothed with a very short, appressed, pale pubes- 

 cence; 1st segment elongate, slightly broader at tip, with a faint tuber- 

 cle on each side before the middle ; 2nd segment about one-third shorter 

 than the 1st; the three basal segments above, except the extreme base 

 of the 1st, stained with piceous ; apical margins of the remaining seg- 

 ments pale; ovipositor about as long as the 1st segment of the abdo- 

 men. Length 9 lines; expanse of wings 15 lines. 



Collection. — -Ent. Soc. Philad. One specimen. 



This does not agree with the description of P. rufus Brulle, which 

 I have not seen, and which is said to inhabit Cuba.
