434 DESCRIPTIONS OF ICHNEUMONID.E ASHMEAD. 



the base of the petiole, basal two thirds of second segment, except the 

 gastrocoeli, and a spot at base of third segment, black ; ovipositor very 

 short. Wings dusky hyaline; stigma and costae black; veins brown; 

 the areolet large, triangular, sessile. 



Habitat. — Washington, D. G. 



Described from a single specimen captured October 17, 1882. The 

 species seems more closely allied to the genus Campoplex, and is placed 

 here doubtfully. 



(?) Limneria erythrogaster sp. nov. 



Female. — Length, 7 mm . This species is an exact counterpart of L. 

 sessilis, but may be at once separated by its triangular, petiolated areo- 

 let and the paler posterior tibia? and tarsi. 



Habitat. — Selma, Ala. 



Described from one specimen received from Mr. W. H. Patton. It is 

 doubtful whether the difference in the areolet will hold to separate this 

 species from sessilis, but until more specimens are taken and the value 

 of this character definitely determined it is probably advisable to con- 

 sider them distinct.

 thorax sloping behind, areolated, the spiracles very small, round. 

 Abdomen black, a small' spot at side of the second segment near apex 

 and the sides of the following segments, rufous; the gastrocoeli poorly 

 defined and situated close to the base of the second segment. Wings

Limneria eurycreontis sp. uov.

 terior coxae, and sometimes the first joint of hind trochanters, black; 

 posterior tibiae at base and apex, aud their tarsi, dusky. Metathorax

 the ovipositor that in its natural position is obliquely directed back- 

 wards over the back, black ; the apex of the third segment and the
