111 Eiipithcda miserulata, the tcnuiiial segment is large, square, and niem- 

 hranoiis, iniicli as in Lygrh dircrsUlneaiu; but the large spatulate claspers 

 end on tlie upper edge in a long, recurv(;d, partly ehitinous hook, meeting with 

 its fellow ()V(!r the spine of the supra-anal plate. This last is membranous, 

 the oxV^(' solid, with a median solid portion from which the spine arises. 

 There is also a large sharp inlVa-anal mueronate ehitinous plate. 



Ill Eupilliccia absi/iif/iiahi, the end of the abdomen is covered with a 

 (•onical nieinbrane covered with scales, in which I could perceiv(^ no sutur(>; 

 aflcr removing the scales with a hair pencil, I was oldiged to rupture the 

 membrane l)el()re laying open the genital armature. The latter then appeared 

 covered with scales. From tliis it would appear that immediately ])revioiis to 

 copulation this mcndjrane is ruptured and possibly cast off. The lateral 

 claspers are very large, long, pointed triangularly. The supra anal plate is 

 shoi't and bread, entirely diil'erent from that of E. mhcrulala; the recurved 

 spine is meml^ranous, forked, and apparently immature The moth was very 

 fresh, and evidently was not sexually mature. 



In one E. auhap/cata which had not copulated, the terminal segment of 

 the abdomen is conical, with no suture above or beneath, but ])erforated at 

 the end, out of which projected the extreme tijis of the lateral claspers. This 

 membranous covering is evidently preputial in its function. The claspers 

 are entirely diflerent from those of the two other species, being widely and 

 unecpially forked. The supra-anal plate is much as in E. miscyulata, but 

 less mend)ianous. The recurved spine is large and solid, with a broad 

 1runeat(_' tip. 



In an individual of Hijdrloinrnu trifasciate, in which the parts of the 

 armature were separated, ajid the insect had evidently used them, they are 

 much as in Lygris inincata; the lateral claspers are, however, much broader 

 at base, snbtriangular at tip; the supra-anal plate is remarkably short, with a 

 median suture, and terminating in a s(juare exjiansion, from which arise two 

 long spines, l)luut, not much curved. Thus, here we have a new character 

 added to separate this genus from Pvlropliora or ( llaiicoptvry.v ; i. c, the liirked 

 su])ra-anal spine. In Eiipithec'ia m\\y have I seen it se|)arate(l, and then in an 

 immature individual. 



Not havitig liirther time to spend on this subject at prc^sent, I will leave thc! 

 matter so far as relates to the Ldrrntiinc, and go to another group, merely 

 rein;irkiuL( in passinif that, alter a study ol" tlie genital ai-mature, it seems an
