several years ago near Berkeley Springs in Virginia. As it is alxjut an 

 inch and a fifth long, it must be that of the largest s{)ecies of the genus.

It agrees with the larva of F. IhkIIhs \n all inijtortant characters, so tliat 

 it will be sufficient here to point nut the diflerences. 



'llic litad is somewhat broader anteriorly and the lateral pieces (man- 

 dibles H are three and not four-toothed as in the other larvte. The surface 

 of the head above is sparsely punctate. Thi palpiforni projections, although 

 minute, are discernible. 



The first tliordcic sr(/)nriif is twice broader than long, narrowed anteri- 

 r»rly. rounded on the sides ; its substance is almost horny. reddish-broAvn ; 

 the surface is punctate, with a longitudinal groove on each side, two trian- 

 gular, darker spots in the middle, especially apparent on the ventral side, 

 and a triangular, sericeous spot between them, near the posterior margin ; 

 this spot is broader on the ventral than on the dorsal side. 



The two fullowlng thorarir and the ahdnminal sripnents, except the last. 

 are covered, above and below, with dense longitudinal striae. Near the 

 anterioi' margin of each, in the middle, there is a sericeous spot, which is 

 rouiul on all segments, on the dorsal as well as on the veiitial side, except 

 on the second thoracic segment above, where it is tridentate. and on the 

 second and third thoracic segments below, where it is reversed truncated 

 heart-shaped. 



T/i' litst ((hdijiniiiid >ieijui,int is of a more horny consistence, deeply punc- 

 tate, hollowed out below. In the middle of the underside there are the 

 same granulations as in the former larva, arranged in concentric rows, 

 round a furrow in the middle. The basis of the same side has deep long- 

 itudinal furrows. The truncated posterior margin of the segment shows 

 two minute. obli((ue, horny points. 



As to the proportions of the segments, the thoi-acic ones are broader than 

 long, the abdcnuinal ones almost square, except two or three intermediate 

 ones, which are a little longer than broad and somewhat narrowed at both 

 ends; the last segment is longer than broad, suboval.
