TENTHREDO KUDIANA, new species 



This species differs from Tenthredo andreas (Jakowlew) by the 

 yellow margins of the pronotum and tegulae, from T. subliTJius 

 (Konow) by the dark stigma, from T. kohli (Konow) by the differ- 

 ent markings of the head and black prescutum. Superficially, the 

 species seems to be allied to T. herixardi (Konow), but it differs from 

 Konow's description in having the face and frons black. 



FetTiale. — Length, 9 mm. Anterior margin of the clypeus broadly, 

 subquadrately emarginate ; head with distinct, although fine, irregu- 

 lar, striato-punctations; the orbits not receding, shining; occiput 

 feebly margined, third antennal joint nearly one-half longer than 

 the fourth; scutum and prescutum opaque with close, well-defined 

 punctures, scutelhmi gently convex not pyramidal, interradius 

 strongly curved, received a little before the apical third; fourth 

 abscissa of cubitus a little less than one-half shorter than the third; 

 tergites finely, transversely aciculate ; sheath straight above, rounded 

 apically and gently convex below. Black; base of mandibles, 

 labrum, clypeus, obscure spot on supracl^'^peal area, malar space, 

 lov.er half of posterior orbits, most of the pronotum, tegulae, oblique 

 spots on scutum posteriorly, most of the scutellum, scutellar append- 

 age, sides and venter of thorax (except an oblique line on mese- 

 pisternum), sternites, tergites laterally, narrow apical margin of 

 first and fourth tergites, tenth tergite and most of the sheath, pale 

 yellow (perhaps with a greenish tinge in life) ; legs pale yellow, 

 anterior legs, intermediate femora and tibiae, posterior femora above, 

 intermediate tarsi and posterior tibia and tarsi, black; head and 

 thorax with short white hair; wings hyaline, venation (including 

 costa and stigma) black.

TENTHREDELLA, species 



A single female from Kudia River, Amagu, Siberia, collected 

 July, 1923, by T. D. A. Cockerell lacks antennae. Tliis species looks 

 much like some of the Nearctic species but differs in details of color. 

 It does not seem to be any of the species listed in Enslin's revision 

 of the Palaearctic forms.
