a series to the editor of Papilio. Should he find them to 

 differ largely from Felder's description, I would suggest the name 

 of '■'■ suffiisa'' for this variety, as it is very constant. 



Description of Larva. 



General color green. Head green, covered with small white 

 points; mouth parts dusky; low down on each side a curved 

 row of four black dots. 



Body clear green, tinged with purplish, and with two lateral 

 yellowish-white stripes. In the dorsal green stripe the purplish 

 tint shows itself as a faint dorsal line, and on the edge of the 

 upper lateral line, leaving clear green between. The upper edge 

 of the upper lateral stripe is clean cut ; the lower edge more dif- 

 fuse, shading into green, and that color being tinged with pur- 

 plish along the upper edge of the lower lateral stripe, which is 

 somewhat broader than the upper one and better defined. Anal 

 segment somewhat horny, narrow, and slightly notched at the 

 tip. Venter, dusky green. Pro-legs black. Abdominal legs dusky 

 green. 



Length i.oo inch. 



Note. — I have in this paper assumed that all the damage done 

 to the yellow pines was caused by P. Menapia. It is only fair to 

 state that, on the edge of the timber, north of Spokane Falls 

 some three or four miles, I came across a large Bombycid larva 

 which denudes the foliage in a similar manner. From one small 

 pine, not more than twelve feet high, I took some thirty speci- 

 mens, and might have taken a hundred. These were in a district 

 where P. Menapia was uncommon. We did not have time to 

 make any extended search on other trees, but it may be possible 

 that a portion of the damage has been done by these insects. It 

 could not have been common, however, in the affected district, as 

 a close watch on the habit of Menapia did not reveal its presence. 

 I have a number of cocoons of this insect, from which I hope to 

 raise the imago, which is probably allied to the genus Parorgyia. 

 If I succeed, I will put the observations on record.

ON THREE SPECIES OF EUCH^TES. 



By a. R. Grote. 



I bring together here the descriptions of three speciesof EucJkb- 

 to which are apparently rare, and possibly not sufficiently distinct. 

 Both Spragnei 2iVid Abdominalis differ from Dr. Clemens' Egleften- 

 sis in having the internal margin of primaries striped as well as 

 the costa. Eglenensis agrees with Abdominalis in having the costa 

 yellow. Dr. Clemens calls it " pale luteous;" but in Abdominalis 

 it is " dark j^ellow,'' as I have described it. Except this charac- 

 ter, which might be held to be variational, the descriptions of the 

 two are very similar, and their identity might be assumed were it
