NEW TENTHREDINID^. 



BY ALEX. D. MACGILLIVRAY, ITHACA, N. Y. 



Fericlista, Knw. — This name was proposed by Knonow in his 

 monograph of the European Blenocampids, published in the " Winer 

 Ent. Zeit.," V. 1886, i86, for those species having the lanceolate cell 

 petiolate, the eyes more or less remote from the bases of the mandibles, 

 and the posterior wings with the outer cells closed by a marginal vein. 

 This name had already been used by Forester, 1869, for a genus of 

 Cynipidse, and I therefore propose the name Mogerus (/^oyepos) to take 

 its place. 



Blennocampa blpariita, Cress. — From an examination of a type 

 specimen of this species, received from the American Entomological 

 Society, I find that this species should be referred to the genus Mogerus. 



Mogerus emargifiatus, n, sp. $ . — Black, with the following parts 

 luteous : the labrum, the femora, the tibise, the base of the tarsi, and the 

 apex of the first, second, third and fourth abdominal segments indis- 

 tinctly so ; the collar and the tegulce, white ; the clypeus, angularly 

 emarginate ; the antennae, thickened at base, especially the third and the 

 fourth segments, the third segments about one-fourth longer than the 

 fourth ; the wings hyaline ; the veins brown ; the costa and the stigma 

 luteous ; the anterior ocellus in a basin which connects with a transverse 

 sinus which is caudad of the posterior ocelli. Length, 6 mm. 



Habitat — Boston, Massachusetts. One specimen. This is the 

 species and specimen referred to by Mr. Harrison G. Dyar in the Can. 

 Ent., XXVI., 1894, 185, as Blenuocampa bipartita, where a description 

 of the larvae has been published. 



Selandria floridana, n. sp. $ . — Black, with the following parts 

 yellow : the clypeus (the labrum is fuscous), the tegulae, a line on the 

 collar, a spot on the mesopleuree, the legs, including the coxje, except the 

 middle and posterior tarsi, the caudal margin of the ventral abdominal 

 segments, and the entire apical segment ; the clypeus truncate ; the 

 labrum rounded ; the antennae slightly thickened in the middle, the third 

 segments one-third longer than the fourth ; the wings blackish-fuscous, 

 paler at apex ; the veins, including the costa and the stigma, black ; the 

 body shining, impunctured ; the lanceolate cell without a cross-vein, open 

 at the shoulder ; the posterior wings with two middle ctlls. Length, 

 4.5 mm. 



Habitat — Ormond, Florida.
