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 piceaella 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 occidentaUs Linn, (arbor-vitae or white cedar), this species 

 I have named thujaella. 



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

 believe to be the true obltqtiistrigella of Chambers. 



On Jiaiiperus communis Linn, (common juniper) is a fourth spe- 

 cies closely allied to the last, which I have mxaed Juniperel/a . 



Two additional species were also bred on conifera which, having 

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



On Finns rigida M.\\\. (common pitch pine) the larvje of Para- 

 lechia pinifoliella 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 I 

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

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

 after tobe 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 Tsuga canadensis Linn, (common hemlock), Recur-oaria api- 

 citripunctella Clem, (^abietisella Pack.) are common as larv?e 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 flat it is very doubtful if the 

 larvae excavate, at least in their later stages.
