AHT. 8 SAWFLIES FROM SIBERIA ROHWER 5 



A single female from Kongaus, Siberia, collected in August, 1923, 

 by T. D. A. Cockerell. This agrees well with Enslin's redescription 

 and there seems to be no reason to doubt the above synonymy. 



AMETASTEGIA GLABRATA (Fallen) 



Two females from Vladivostok collected July 31, 1923, by T. D. A. 

 Cockerell; and one female from Okeanskaja, Siberia, collected Au- 

 gust, 1923, by T. D. A. Cockerell. 



DOLERUS OKEANSKAJENSIS, new species 



In general appearance and color very closely resembles the Nearc- 

 tic species similis Norton and allies but differs from all of these in 

 details of the sculpture of the head and thorax and in the shape of 

 the sheath. From variegatus ^1 akowlew it may be separated by the 

 pale lobes of the scutum, from armillatus Konow the pale tegulae 

 and broader rufous band on the abdomen will distinguish it. 



Female. — Length, 9 mm. Clypeus with a rather narrow, deep, sub- 

 arcuate emargination, the lobes broad, truncate, the surface covered 

 with coarse, contiguous punctures; frons coarsely punctured; an- 

 tennal furrows shallow ; posterior orbits and sides of vertex shining 

 but with separate distinct punctures ; postocellar furrow faintly indi- 

 cated ; postocellar area with elongate, contiguous punctures ; prescu- 

 tum with well-defined, rather large, close punctures (punctures rather 

 closer medianly) ; scutum laterally punctured like the prescutum but 

 medianly with the punctures closer and smaller ; scutellum with close, 

 large, uniform punctures; postnotum (scutellar appendage) longi- 

 tudinally aciculate on an opaque surface, without a distinct median 

 ridge ; mesepisternum punctato-reticulate, mesosternum shining with 

 scattered, rather small, but well-defined punctures; sheath broad, 

 acute apically, tapering below; antenna shorter than the head and 

 thorax; the median joints of the flagellum compressed, the first joint 

 distinctly longer than the second which is subequal with the third; 

 tergites polished. Black; pronotum, prescutum, scutum (except im- 

 mediately in front of the scutellum), tegulae, abdominal segments 

 two to five, inclusive, rufous; legs, black; the under side of the an- 

 terior femora, the anterior tibiae, the intermediate tibiae obscurely 

 beneath, rufous. Body, densely clothed with long gray hair. Wings 

 hyaline; venation black. 



Male. — Length 9 mm. Head sculptured like the female except the 

 vertex is more closely punctured posteriorly the sides of the prescu- 

 tum have the punctures more widely separated. Black; anterior 

 femora beneath at the apex, the entire anterior tibiae, rufous. More 

 densely clothed Avith white hair than the female. 



The paratype male has the base of the intermediate tibiae obscurely 

 rufous, and the posterior tarsi are brownish.
