July 19. — The soil in the breeding-cage was sifted, and a number of cocoons of 

 this saw-fly, y^ of an inch long by about half as wide, taken from it. ( Fig. 1, a.) The 

 cocoon consists of two cases: the outer is dark, and covered with soil exteriorly, the 

 inner surface brown-hued and glossy. The inner case is of a firmer texture, and of 

 a showy crimson color, with pearly reflections on the inner surface. The cocoons 

 contained contracted dormant larvfe; and when last examined, February 15, '87, no 

 change had taken place; and it is probable that the pupal stage will be acquired but 

 shortly before the appearance of the mature insects. 



My observation of this saw-fly for the last two years leads to the belief that it is 

 on the increase, and may at any time multiply to an injurious extent. With a view 

 to find some easy means to check its ravages, a number of infested cedars were 

 sprayed with a strong kerosene emulsion. About one-fourth of the larvse died within 

 twenty-four hours after the application; the others were apparently uninjured, though 

 care was taken that all the larva? should be reached. Experiments will be instituted 

 the coming summer, looking to the discovery of more satisfactory results. 



LOPHYKUS (MONOCTENUS) JUNIPEKI, n. Sp. 



Female: Luteous yellow, shining; head and thorax slightly tinged with fulvous; 

 a semi-circular line on the vertex covering the ocelli, tips of the mandibles, antennse, 

 excepting the two basal joints, mark on each side of the mesothorax, lateral scutellar 

 region, tip of scutellum, metathorax, posterior portion of pectus, anterior margin 

 of the basal plates, sides more or less of three or four or more — varying in different 

 specimens — of the basal segments of the abdomen, central portion of the venter, 

 sheaths, and tip of ovipositor, black; antennae short, serrate, thirteen- jointed, the 

 two basal joints in most cases luteous, tinged with fuscous. (In a few specimens the 

 antennae were entirely black, and in others and more commonly, the second joint 

 only was luteous.) Mesothorax and scutellum smooth and polished; wings hyaline, 

 iridescent, nervures and stigma black or fuscous, dividing nervure between the first 

 and second submarginal cells hyaline, lanceolate cell contracted in the middle; tips 

 of tarsi fuscous. 



Length .35 inch. 



Described from thirteen specimens. 



Male: Shining black; palpi, sides of prothorax, and base of wings, luteous; an- 

 tennas usually seventeen-jointed, (about one-third of the specimens examined having 

 but sixteen joints,) entirely black, and all but the two basal joints strongly pecti- 

 nate; wings hyaline, iridescent, nervures and stigma black or fuscous, dividing 

 nervure between the first and second submarginal cells hyaline, lanceolate cell con- 

 tracted in the middle; legs luteous; coxa?, trochanters, and tips of tarsi, fuscous; ter- 

 minal points of the abdomen and a wide stripe on either side of the venter, luteous. 



Length .30 inch. 



Described from thirty-six specimens.
