TRIGONALID WASPS — TOWNES 303 



Genus Bareogonalos Schulz 



Bareogonalos Schulz, In Wytsman, Genera insectorum, fasc. 61, p. 18, 1907. 



Type; Trigonnlys canadensis Harrington. Monobasic. 

 Nippogonalos Uchida, Ins. Mats., Sapporo, vol. 3, p. 79, 1929. Type: Nippo- 



gonalos jezoensis Uchida. Original designation. 



This genus is easily distinguished by its pyramidal postscutellum, 

 bifid apically, and the 1-segmented trochanters of the female. The 

 members of the genus are larger and more robust than the average 

 trigonalid. Vespa and Vespula have been recorded as hosts. 



Through the generosity of Prof. T. Uchida I have been able to 

 compare specimens of the Japanese species B. jezoensis with the 

 American B. canadensis. They are rather closely related. The 

 Japanese species has the scutellar elevation lower, thoracic sculpture 

 a Uttle coarser, and the coloration of the forewing different. In 

 jezoensis the forewing is subhyalme with the apical 0.4 lightly inf uscate ; 

 in canadensis the forewing is yellowish hyaline with the radial cell 

 rather strongly infuscate and the apical margin faintly, broadly 

 infuscate.

 Description of male. 



Bareogonalos canadensis Schulz, in Wytsman, Genera insectorum, fasc. 61, pi. 3, 

 figs. 82-90 (colored), 1907. 



AIale: Forewing about 8.5 mm. long. Black. Hind corner of 

 pronotum, postscutellum, lateral spot on propodeum, small marks on 

 coxae, trochanters, bases and apices of femora, tibiae, tarsi and 

 lateral triangular spots on tergites 2-6 (diminishing in size posteriorly) 

 yellow; apical part of hind tibia tinged with brown; wings subhyaline, 

 the radial cell and adjacent areas somewhat infuscate. 



Female: Forewing about 11.5 mm. long. Colored like the male 

 but with the yellow marks more extensive, the marks on tergites 2-6 

 broadened and fused into conspicuous transverse yellow bands, 

 sternites 1 and 2 \vith yellow marks, scutellum mostly yellow, meso- 

 scutum anteriorly with a yellow spot just inside the notaulus, a 

 yellow spot just forward and laterad of the scutellum and of the 

 postscutellum, and a small yellow spot on the mesopleurum.
