Egg.— (Fig. 18.) 

 When first laid, the egg is a pale yel- 

 lowish brown, later changing to ochre- 

 ous brown, and finally to jet black. It 

 measures 0.65 by 0.30 mm. This in- 

 sect lives o upon the pine throughout the 

 summer, and the winter eggs are de- 

 posited on the blackish leaf sheath at 

 base of leaves of the same plant. 



Outside of Nebraska, the type local- 

 ity of Eulachnits rileyi, this species 

 has been reported from Albany, N. 

 Y., under the name Lachnus agilis 

 Kalt.,by Prof. C. P.Gillette.* The 

 writer has collected it on the Austrian 

 or black pine (Pinus auslriaca) at 

 Chicago, Morgan Park, and Urbana, 

 111.; Independence, Iowa; La 

 Fayette, Ind., and, in company 

 with Mr. Monell, at St. Louis, Mo. 

 Mr. Monell has specimens in his 

 cabinet collected by Mr. Theo. 

 Pergande in 1882 and 1885 at Wash- 

 ington, D. C, on the Jersey or scrub 

 pine (Pin us inops), and he has him- 

 self collected it at various times 

 since 1905 at St. Louis, Mo., on Pinus austriaca.
