216 AMERICAN HYMENOPTERA. 



longed so as to make the anterior margin of the clypeus appear beaked. The 

 vertex and cheeks are closely confluently pnnctured, but shining, and the latter 

 covered with a rather dense appressed silvery pubescence. Thedorsnlum has a 

 rather abundant appressed silvery pubescence, which does not, however, obscure 

 the sculpture. The scutellum is sculptured and ornamented in much the same 

 way as the dorsulnm. The squamae are prolonged posteriorly into a rather blunt 

 angle, which is directed backward and inward. The spine of the postscutellum 

 has parallel sides, and the width of the apical truncation is a little less than one- 

 third the length of the spine. The mesopleura, excepting for a large space on the 

 anterior half, which is polished and very sparsely punctured, are punctured in 

 much the same way as the scutellum, and also with appressed silvery pubescence. 

 The dorsum of the metathorax has the sculpture obscured by appressed silvery 

 pubescence. The metapleura shining, mostly granular and partly smooth. The 

 posterior aspect of the metathorax is granular and has a median rather tear- 

 shaped polished sulcus. The abdomen is shining and rather closely, distinctly 

 punctured. On the first dorsal abdominal segment there is a median, longitudi- 

 nal shallow sulcus. The first dorsal abdominal segment is rather conspicuously 

 clothed with appressed silvery pubescence, which forms rather conspicuous bands 

 on the margins of the second, third and fourth dorsal abdominal segments. The 

 fifth dorsal abdominal segment is rather inconspicuously pubescent. The pygi- 

 dial area has appressed golden hairs or bristles. 



Color. — Black. The tlagellum brownish orange, the pedicellum and apex of 

 scape brownish. Mandibles mostly blackish, partly castaneous. Pronotum with 

 a yellow mark on either side. Tubercles, the anterior tibiie and metatarsi on the 

 inner aspect, the middle and posterior aspect, and the posterior margin of the 

 first dorsal abdominal segment with a mark on either side more or less yellow. 

 The anterior tarsi mostly yellowish, the anterior tibise, the middle and posterior 

 tarsi brownish, middle tibise brownish. The apical margins of the second, third 

 and fourth dorsal abdominal segments brownish yellow. The fourth, fifth and 

 sixth abdominal segments brownish to castaneous. The squamae yellowish, and 

 yellowish testaceous, the apical half of the spine of the postscutellum translucent 

 yellowish.

In structure very like Limnerium rivalis Ci'ess. ; it is readily dis- 

 tinguished from that species by the almost entirely black abdomen.

 could not be compared because they had been lost through breakage.
