5 6 . Closely allied to and resembling 0. ovaUs (p. 369) ; differs 

 primarily in belonging to the subgenus Ancistrocerus, Wesm.,with 

 a transverse suture on the basal abdominal segment, not IJo- 

 notus, Sauss., which has the 1st abdominal segment rounded and 

 steep at base ; it differs also considerably in markings. Head, 

 thorax, and abdomen closely and somewhat coarsely punctured, 

 on the abdomen, except along the margins of segments 1-4, the 

 punctures are rather shallow ; clypeus small, pentagonal, apex 

 transverse or slightly emarginate ; median segment not depressed 

 vertically beneath the postscutellum, slightly sloping; the sides 

 posteriorly rounded, with a rather deep medial longitudinal 

 furrow; basal segment of abdomen narrowed and with a pro- 

 minent transverse suture at base. Yellow ; a large triangular spot 

 on the vertex of the head, the mesonotum anteriorly and along 

 the sides broadly, all the sutures between the parts of the thorax, 

 an irregular spot at the base of the 1st abdominal segment, and a 

 transverse band at the base of the 2nd segment, giving out a large 

 square wedge-shaped mark in the middle posteriorly, and prolonged 

 back on each side along the lateral margins of the segment, black 

 or rusty rufescent black ; wings clear hyaline.

Mr. Gumming, who was kind enough to send me a small collec- 

 tion of hymenopterous insects from Persia, had a note to the effect 

 that this species was a regular nuisance, coming into the house 

 and stopping up keyholes etc. with clay.

" S . Length 4^ lines ( = 10 mm.). Ferruginous, the clypeus and 

 face as high as the top of the notch in the eyes, the scape of the 

 antennae in front, the mandibles and cheeks yellow ; the stemmata 

 are enclosed in a black coronet-shaped spot on the vertex ; the 

 margin of the prothorax, the tegulse and posterior portion of the 

 tubercles, the anterior and intermediate tibiae and tarsi, also their 

 coxae in front yellow ; the lateral margins of the scutellum and 

 postscutellum, and also the margins of the collar stained more or 

 less with yellow — all the impressed divisions of the thorax are 

 stained more or less black; a dark fuscous spot occupies the mar- 

 ginal cell, extending a little beyond; abdomen, the apical margins 

 of the segments are more or less of a yellowish tinge, as is also 

 the 2nd segment beneath ; the 2nd and 3rd segments above are 

 black at their basal margins."
