has gone he is of the opinion that the most reUable specific characters 

 are to be found in the sheath, saw, antennae, certain parts of the head 

 and color. Certain characters of the head such as the exact extent 

 and definition of the median fovea and antennal furrows and the exact 

 dentations of the clypeus are, it would seem, subject to variation and 

 cannot be used as rigidly as in other groups. 



Empria fragarice, new species 

 Judging from the literature this species is related to castigata Mac- 

 Gillivray. Specimens were sent to Dr. A. D. MacGillivray who com- 

 pared them with his type and stated that they differ from that species 

 in the ''form of the saw guide which has the distal end truncate with 

 rounded corners, while in the specimen sent the lower corner is rounded 

 off. The median fovea is only a rounded scar in castigata and a deep 

 rounded pit in the specimen sent." This species has no doubt been 

 identified as ignota Norton, and probablj^ some of the writings dealing 

 with the biology and economics of ignota refer more properly to fra- 

 garice. 



Female: Length 6.5 mm.; length of antennse 2 mm. Clypeus more coarsely 

 sculptured toward the apex, the apical margin tridentate, the lateral lobes broadly, 

 obtusely triangular with the median tooth small and obtuse; supraclypeal area 

 convex, slightly more strongly convex ventrally, but in outline nearly rectangular; 

 antennal and supraclypeal fovese confluent, but the former are not as deep as the 

 punctiform supraclypeal fovese; antennal furrows complete but not as deep opposite 

 crest; middle fovea elongate, and more or less connected with the elongate depression 

 from the anterior ocellus; postocellar area well defined; postocellar furrow nearly 

 straight; a deep furrow from the anterior ocellus to the postocellar furrow; postocellar 

 line distinctly shorter than the ocellocular line; face and front to the level of the 

 anterior ocellus distinctly sculptured; vertex and posterior orbits shining, with seti- 

 gerous punctures; antennae short, stout, the third antennal joint distinctly longer than 

 the fourth, the fourth and fifth subequal; mesonotum shining, impunctate; stigma 

 broader at base where it is subangulate, gradually tapering to the radius from which 

 it is obliquely truncate to the costa; third cubital cell slightly longer than the second, 

 twice as wide anteriorly as basally; hind wings with one discal cell; sheath straight 

 above, obtusely rounded at the apex and gently rounded on the lower margin. Black; 

 two elongate spots on the posterior margin of the pronotum, tegulae almost entirely, 

 lateral spots on the second, third and fifth tergites, white; legs black; apices of the 

 four anterior femora, four anterior tibise beneath, extreme base of the posterior tibiae, 

 white; wings dusky hyaline, venation dark brown. 



Male: Length 5 mm. Agrees fairly well with the above description of the female. 

 The hypopygidium is broadlj' rounded. 



According to the specimens examined this species varies in the dentation of the 

 clypeus, inasmuch as the median tooth is decidedly reduced in some specimens and 

 slightly accentuated in others (in these latter the supraclypeal area and clypeus 

 become subcarinate) ; and in the extent of the middle fovea, as the impressed Hne 

 from the anterior ocellus varies in depth and definition. The most reliable criterion 

 for determining this species is the shape of the shpath, general color, well-defined 

 postocellar area and short antennae.
