U. S. National Museum is an entirely different species. Therefore, 

 Fig. 284 represents a species until now undescribed and which I pro- 

 pose to call piceaelhi after its food plant, red spruce in New England 

 and black spruce in Northern New Jersey. 



Very closely allied to this species, and difficult to separate in the 

 perfect state, except for its average smaller size is a species that feeds 

 on Thuja occideuialis Linn, (arbor-vitae or white cedar), this species 

 I have named thujaella. 



On Jiiuiperiis virginiana Linn, (red cedar) I have bred what I 

 believe to be the true obliquistrigeUa of Chambers. 



On Jiiniperus couuminis Linn, (common juniper) is a fourth spe- 

 cies closely allied to the last, which I have wzxntA jiiniperella . 



Two additional species were also bred on conifera which, having 

 similar larval habits, may be included in the following brief synopses. 



On Piniis rigida Mill, (common pitch pine) the larvae of Para- 

 lechia pijiifoIieUa Cham, are common throughout northern New Jersey. 



On account of its larval habits I am inclined to place this species 

 under the genus Recurvaria, but refrain owing to a strong protest 

 from my friend Busck whose opinion on the general subject and 

 especially generic distinctions I have much respect for ; although 1 

 am not convinced that he is entirely right in placing pinifoliella — a 

 miner of pine needles and our old friend iiiscripta Wlsm. (but here- 

 after to be known as cristifasciella Cham.), whose larva lives on oak, 

 between two leaves fastened together with silk, both together in his 

 new genus Paralechia ; and while the venation of these two species 

 may be identical, their appearance, in outline, coloration and general 

 superficial characters, as well as their habits, are very different. 



On Tsiiga canadensis Linn, (common hemlock), Reai/Tan'a api- 

 citripiinctella Clem, (^abictisella Pack.) are common as larvae in March 

 and April in North Jersey. 



The five first-named species are distinctly miners, excavating and 

 living within the leaflets or needles ; I was somewhat doubtful about 

 this being the case with the two juniper species, as juniper leaflets are 

 very much contracted at the joints, but careful examination with a 

 lens proved that narrowed as they are they are hollowed out in exactly 

 the same fashion as by the feeders on the long leaf pine and shorter 

 leaf spruce. 



The leaf of the hemlock is so very fiat it is very doubtful if the 

 larvae excavate, at least in their later stages.
