A female belonging to the Public Museum of Milwaukee, 

 collected in Milwaukee Co., Wis., Aug. 12, 1907. No. 24,301. 



This species is near to R. pedicellatus Pack, but the longer 

 third antennal joint ; the absence of the basal enclosure of the 

 metathorox, and the black coxae will separate it at once in the 

 female sex. The male was separated in the original descrip- 

 tion. 



I have bred this species from pupae in old stems of the cul- 

 tivated currant (Ribes) . A $ hatched April 27, 1907. 



Crabro (Protothyreopus Ashm.) dilectiformis n sp 



9 . Length 14 mm. ; width of head 3.5 mm. Robust, stout. Clypeus 

 with a strong medial carina at the apex of which is an obtusely rounded 

 tooth ; the apical margin smooth, without hairs. Space between the 

 eyes at the clypeus a little less than the width of the clypeus, including 

 the rounded tooth. Facial basin smooth, shining. Third joint of the 

 antennae equal to the length of the antennal joints 4 and 5. Ocelli in a 

 low triangle. Space between the lateral ocelli less than the distance 

 from one of them to the nearest eye margin. There is a faint indication 

 of a carina from between the lateral ocelli to the occiput, it is much 

 stronger between the ocelli than elsewhere. Head rather finely, closely 

 punctured, the punctures are sparser on the cheeks and occiput. Pro- 

 notum in front strongly, longitudinally striated ; not very strongly, 

 but distinctly ridged anteriorly, dentate laterally; broken in the middle. 

 Dorsulum rather coarsely, closely punctured, the punctures becoming 

 a little sparser posteriorly. Mesoplurse above striate, below striato- 

 punctate. Scutellum striato-punctate. Postscutellum sparsely punctur- 

 ed. Metanotum coarsely, longitudinally striated ; with a deep central 

 furrow, posterior face not so coarsely or closely, transversely striated, 

 with a deep central furrow. Metaplurae finely, transversely stn.ilol, 

 more coarsely so anteriorly. Anterior femora triangular, keeled above 

 posteriorly. Four posterior tibiae serrate. First recurrent nervure a 

 little more than half the length of the first transverse cubitus basad of 

 the cubitus. Abdomen closely punctured, first segment more strongly
