lOO KINCAID 



[360] 



A single specimen from Saldovia agrees with the above in structure 

 but lacks the red band upon the abdomen. It may be a variety of this 

 species. 



EMPHYTUS ANGUSTUS sp. nov. 



Male: Length 6 mm. ; body very slender, head shining, finely and 

 sparsely punctured, much narrowed behind the compound eyes ; ©cellar 

 area very convex ; clypeus slightly, circularly emarginate ; antennas a 

 little shorter than head and thorax, slender, third joint considerably 

 longer than fourth ; joints six to nine, contracted at base and apex ; 

 stigma slender, gently rounded beneath, apex acute. Color black; 

 under surface of antennae obscurely testaceous ; basal joint of antennae, 

 labrum, clypeus, greater part of pronotum, tegulae, and triangular spot 

 on pleura, pure white ; diamond-shaped spots of a yellowish-brown 

 color on dorsal abdominal segments one to six; legs white; upper sur- 

 face of femora, the tibiae and tarsi more or less infuscated ; wings 

 hyaline, nervures and stigma brown. 



One male, Kukak Bay, July 4. 



Type no. 5308, U. S. National Museum. 



Allied to Emphytus apertus Norton, but in that species the clypeus 

 is more deeply emarginate, the antennae are shorter, stouter, and more 

 tapering, the basal joint of the antennae is black and the legs are dif- 

 ferently colored.

In 1822 Eschscholtz described two sawflies from Unalaska, to which 

 he gave the names Tenthredo nigrofasciata and Tenthredo subcee- 

 rulea. The latter has since been rediscovered and is a genuine Ten- 

 thredo, but the generic position of his Tenthredo nigrofasciata has 

 been in considerable doubt. Norton in discussing this species in his 

 catalogue suggests that it might be a Macrophya. Kirby in his list of 

 the Hymenoptera in the British Museum places it doubtfully in Em- 

 phytus, and in this he is followed by Dalla Torre in his catalogue of 

 the Tenthredinidae and Uroceridae.
