SOME SPECIES OF THE GENUS LEUCOSPIS. 1 
By Charles T. Brues. 
The recent paper by Mrs. Weld 2 has encouraged me to 
undertake the identification of the species of Leucospis which 
have accumulated in my collection. Among these are several 
undescribed forms of which descriptions are given below, to- 
gether with a few notes on known species, mainly in regard to 
their geographical distribution. 
Leucospis birkmani sp. nov. 
$ . Length 12.5 mm. Black, with yellow and ferruginous 
markings and strong metallic reflections. The yellow is dis- 
tributed as follows: antennal scape; median round spot near 
anterior margin of pronotum; entire posterior and lateral mar- 
gins of pronotum; transverse band on mesonotum just before 
base of scutellum; four anterior knees; triangular spot at base 
of hind femur below and band along apical two thirds of upper 
edge; outer two thirds of hind tibia and extreme outer tip of 
hind coxa. The ferruginous markings include the base of an- 
tennal scape; tegulse; inner side of front femora and their tibiae 
and tarsi; middle legs; hind coxae, except lower surface; inner 
margin of hind tibiae and their tarsi entirely; sides of propodeum; 
middle of first abdominal segment above and the elongate 
ventral plates of the abdomen. Face finely punctate reticulate; 
inter-antennal projection with a strong median carina; nar- 
rowest width of face clearly less than its height; malar space 
.one-third longer than the second flagellear joint; ocelli on a 
distinctly elevated tubercle, the paired ones as close to one 
another as to the eye margin; occipital margin prominent 
medially, as high as thd ocellar tubercle; vertex rather finely 
punctate, confluently so in front; occiput irregularly reticulate, 
aciculate only near the middle. Antennae with the second and
