102 THE CANADIAN ENTOMOLOGIST. 



of Say is readily distinguishable from E. reseda, Panz. I have not com- 

 pared the Cymus. Dr. Horvath in the second paper cited sets forth the 

 distinguishing characteristics of the new species, and they need not be 

 cited here. 



As to the others, Nezara vividula is practically of world-wide 

 distribution, and is said to occur in Florida, but I have never seen it from 

 that section; Zicrona coerulea is credited to the Western States, but I have 

 not yet succeeded in getting an example from this country ; Corizus 

 crassicornis and Nysius thymi also occur in this part of the country, but 

 nothing short of an abundance of good material and a critical investigation 

 could fix the fact beyond doubt. 



I sincerely hope that the day is now at hand when American 

 Entomologists will break the enslaving shackles of tradition and emerge 

 from the frame of mind so akin to ancestor worship that seems to still 

 obsess them. While we should respect the work of our predecessors, the 

 pioneers in a sterile field, I fail to see the necessity of following in their 

 footsteps, stepping cautiously into each footprint, like Indians on the 

 warpath. It is really distressing, when expecting new light on an old 

 subject, to meet with nothing but a repetition of the old errors which make 

 the clear waters of science as murky as the ocean from the cuttle's ink. 



TWO NEW SPECIES OF SAW-FLIES. 



BY ALEX. D. MACGILLIVRAY, ITHACA, N. Y. 



The two following descriptions are offered at this time in order that 

 the species may be properly recorded in the new list of New Jersey insect 

 in course of preparation : 



Pcecilostoma convexa, n. sp. — Body black, with the labrum, the 

 clypeus, the angles of the pronotum, the tegulae, the trochanters in part, 

 the femora above more or less, and at apex, the front and middle tibiae, 

 more or less infuscated on the apical half, the tarsi at base, and an ovate 

 spot on each side of each abdominal segment, white or brownish-white ; 

 the antenna! fovea large, angled above ; the antennal furrows entering the 

 anyle in the antennal fovea, punctiform adjacent to the antennae, some- 

 what obsolete or broadly indicated on the front, becoming a fine line like 

 furrow opposite the lateral ocelli, becoming broader on the vertex and 

 extending to the occiput ; the median fovea small, well-like ; situated
