ACORDTTLECERA PARVA, new species. 



Related to foveata Rohwer, but the postocellar line is one third 

 longer than the ocellocular line; and the hind tarsi are pale. 



Male. — ^Length 2.5 mm. Hypopygidium broadly rounded apically. 

 Black; antennae, clypeus, labrum, mandibles (apices piceous), and 

 legs yellowish-white. Venation pale brown; wings hyaUne. Face 

 without white hair. 



Fort Lee, New Jersey. Four males bred from larvae collected on 

 young leaves of black oak. Van Cortland Park, New York. One 

 male bred from larvae collected on young leaves of black oak. Larvae 

 collected in the spring. Collected and bred by Dr. H. G. Dyar. 



2Vpe.— Cat. No. 14419, U.S.N.M. 



One of the males has transverse radii in both wings. 



B. Middle fovea wanting. 



b. Abdomen entirely rufo-testaceous. 



ACORDULECERA ERYTHROG ASTRA, new species. 



Judging from the description this species is colored like A. maxima 

 MacGillivray, but the ocellar basin of that species is said to be wanting 

 and the relation of the antennal joints is different. 



Female. — ^Length 4 mm. Labrum obtusely angled apically; 

 clypeus subconvex; antennal furrows complete to the ocelli, where 

 they end abruptly; postocellar line subequal wdth the ocellocular line; 

 first joint of the flagellum somewhat longer than the second. Black; 

 apical part of clypeus, labrum, mandibles (apices piceous) and legs 

 (except hind tarsi which are brown) yellowish-white; pronotum and 

 abdomen rufo-testaceous. Wings hyaline; venation dark brown, 

 lower part of stigma pale brown. Face with rather dense white hair. 



Great Falls, Virginia. One female collected May 12, 1911, by 

 S. A. Rohwer. One female from Georgia. 



Type.— C&t. No. 14420, U.S.N.M.

 Acordulecera dorsalis: Dyar, Joum. N. Y. Ent. Soc, vol. 5, p. 199. 



Female. — Length 4 mm. Labrum rounded anteriorly; clypeus 

 with the apical margin depressed, basally convex; supraclypeal area 

 convex below, flattened above; frontal furrow long and at some 

 angles the middle fovea seems to be present but it is not; antennal 

 furrows complete to the lateral ocelli, where they form a shallow 

 depressed area; a punctiform fovea on postocellar line behind the 

 anterior ocellus ; postocellar line very little longer than the ocellocular 

 line; first joint of flagellum longer than the second. Black; clypeus, 

 labrum, mandibles (apices piceous) , palpi, legs (apical four joints of
