Notes upon some of Mr. Walker's Species of Geometridse. 



By Geo. D. Hulst. 



Not long since by the kindness of Dr. Packard, I received from him 

 for studs-, some 36 colored drawings, prepared for him in London, of 

 types of American Geotnetridai in the British Museum collection. Dr. 

 Packard had these drawings when he prepared his Monograph, and some 

 of Walker's species were thus made known to us, and these, with others 

 not identified, were represented in his plates at the end of the Monograph. 

 From a study of these drawings I make the following notes after com- 

 parison with material in my possession. 



Caberodes antidiscaria Walk. (C. B. M. Geom. p. 15 13, 1862). 

 I find, I have been mistaken in my determination of this species from 

 the figure in Packard's Monograph ; and as a result I redescribed it, as 

 Endropia leniaria. The species seems to be a good one. 



Endropia tiviaria Walk. (C. B. M. Geom. p. 250, i860), seems 

 fr< »m the drawing to be a variation of E. obtusaria Hiibn. But the drawing 

 does not seem in coloration to agree with the description of Walker. As 

 it stands, however, I would call it a variety of E. obtusaria Hiibn. The 



description seems to be nearer than the drawing. 



Azelina rectisectaria H. Sch. (Aus. Schm., f. 325). Under 

 this name Herrich-Schaeffer describes an insect from Brazil, which is, I 

 think, the insect afterwards described as A. zalusaria by Walker. The 

 colored drawing does not show this insect to be so pinkish as many Q 

 specimens from Florida. Among my $$ however I have specimens 

 exactly agreeing with Mr. Walker's insect, except that they do not have 

 pectinated antenna?. But for this I would look upon it as a not very 

 aberrant variety of A. hubneraia, so far as the males go, but with the fe- 

 males quite considerably differing. At any rate I would take Walker's 

 zalissaria to be a synonym of rectisectaria H. Sch. 



Selenia alciphearia Walk. (C. B. M. Geom. p. 184, i860). 

 This is not the insect represented by Dr. Packard's figure and descrip- 

 tion, but is the same exactly with Selenia kentaria Grt. and Rob. So the 

 latter name falls. Of the insect which Dr. Packard supposed to be £". 

 alciphearia, I have never seen a counterpart ; but it is very close to the 

 spring form oi Walker's species, and that is what it possibly is. As with 

 the European species the two broods very materially differ. 



Geometra inclusaria Walk. (C. B. M. Geom. p. 508, 186 1.) 

 This is without doubt the same as the insect afterwards described as 

 Aplodes rubrolineata by Dr. Packard. The red edging to the wing is 

 somewhat heavier in the more southern specimens.
