Pelopoeus cementarius, Smith, Brit. Mus. Cat. Hym. iv, p. 234. 

 Collection. — Ent. Soc. Philad. Twelve specimens. 



Prof. Poey informs me that this species " makes its nest of moist 

 earth, about twenty cells approximated and covered by a general layer. 

 The 9 deposits an egg in each cell, which she fills afterwards with 

 spiders, after having pricked them with her sting. The effect of the 

 wound is to paralyze the legs of the spider, which preserves, for about 

 thirty days, its flexibility and its colors. The nest is made under roofs."

Black: face golden; base of antennre, prothorax, tegulse, spot beneath ante- 

 rior wings, scutellums, spot behind posterior wings, large lunate mark at tip of 

 metathorax, legs in part, the petiole beneath and the first segment of abdomen, 

 yellow ; rest of abdomen brownish, the apical margins of the segments testace- 

 ous ; wings fusco-hyaline. 



Female — Head black, clothed with pale yellowish pubescence, more 

 dense on the cheeks; the face and clypeus golden ; antenna? black, the 

 basal joint yellow, the two following joints more or less tinged with fer- 

 ruginous. Thorax black, opaque, slightly pubescent ; the prothorax, 

 tegulae, a large spot just beneath the anterior wings, the scutellum and 

 postscutellum, a large, sublunular mark on the tip of the metathorax, 

 and an elongate spot on each side at extreme base behind the posterior 

 wings, yellowish; metathorax covered with dense, minute, transverse 

 striae, the dorsal middle prominent. Wings uniformly tinged with yel- 

 lowish-fuscous, the nervures pale ferruginous. Legs black ; the four 

 anterior femora, except extreme base, their tibiae and tarsi entirely, the 

 posterior trochanters, their femora at base, the basal half of their tibiae 

 and tarsi, yellowish ; apical half of their tarsi fuscous. Abdomen fus- 

 cous, the petiole black above, yellowish on the sides and beneath, the 

 first segment entirely yellowish, except a pale fuscous stain at the base, 

 apical margins of the remaining segments narrowly pale testaceous. 

 Length 9> lines; expanse of wings 13 lines. 



Male. — Colored like the female, except that the abdomen beyond the 

 first segment, is fusco-ferruginous, with the apical margins of the seg- 

 ments faintly paler. Length 9 lines ; expanse of wings 12 lines. 



Collection. — Ent. Soc. Philad. One 9 > tw° £ specimens. 



Very closely allied to P. cementarius, but is readily distinguished by 

 the different coloration of the wings, legs and abdomen. The name 

 adopted above for this species was communicated to me by Prof. Poey.
