168 THE ENTOMOLOGIST. 



I had at first thought that palceno should be made the type of 

 another section, as it differs from group II. in having both sexes 

 with an unspotted fascia ; but however different it may be from 

 hyale in typical specimens in this respect, the connecting link 

 to the rest of the group is made by the female variety werdandii, 

 Herr-Schaff., which has a faintly-spotted marginal fascia; and 

 as the chief characteristic of this group is the similarity of both 

 sexes, I place 2)aI(eno here. 



The genus EriocoUas, however, affords a very sharp character 

 of definition by its possession of the interesting secondary sexual 

 character, the congested scale area on costal margin of secon- 

 daries; there is one point to which I might call attention in 

 regard to these secondary sexual characters, and that is their 

 constancy. I have only seen one specimen of Eriocolias which is 

 without it, and that is a specimen of E. fieldii. Men., in my 

 collection from the N. W. Himalayas. This was received along 

 with other typical specimens, and is in all respects (except the 

 absence of the scale patch) perfectly typical. This aberra- 

 tion is equalled, but in an entirely opposite manner, by a male 

 specimen of the Indian Papiho paris, Lin., in my collection, 

 which has on the first median nervule (but in a less pronounced 

 manner) the characteristic androconia normally found on median 

 and submedian nervules of superior surface of primaries of 

 P. ganesa, a species which is found flying in company with 

 P. paris. It will be noticed that this streak of dark brown 

 filamentous scales is found only on the nervule of jmvis, which 

 is in f/anesa and its allies the most endowed with this type of a 

 secondary sexual character. 



LIFE-HISTOEY OF TENTHREDOPSIS MICROCEPHJLA. 

 By Miss Chawner. 



On the 8th of May, 1893, I captured two females of Tenthre- 

 dopsis microcepliala, and placed them with some live turf in a 

 case I use for the purpose of breeding sawflies. No other flies 

 were confined there while the T. microcepliala were in it. The 

 turf was composed of grass- and buttercup-roots. The next few 

 days being dull, the flies remained apparently torpid, but May 

 15th was brighter, and they became lively, examining the turf, 

 and evidently seeking a suitable leaf on which to oviposit. The 

 result I copy from notes taken at the time. 



May 15th, 1893. — One fly laid an egg on the under side of a 

 buttercup-leaf, near but not touching one of the large ribs. Egg 

 oval, brownish, in the centre of a largish blister. 16th-20tli. — 

 Several eggs laid daily, about twenty in all ; two or three often 

 close together on one leaf. 29th-31st. — Larvae hatching. Length
