more genera, one of them, Idlina, an Eumorphid geuud, the two 

 others Daphnid. 



Head rather prominent and projecting. Antennae of almost uniform thick- 

 ness throngbout in both i and ? , the tip very pointed and sharply hooked. Legs 

 long and slender, with closely compressed hairs on tibiae; spines on tibiae most 

 developed on median pair. Forewing long and narrow, straight, to just before 

 apex ; outer margin almost straight ; inner margin very slightly curved after 

 leaving tornus. Hindwing long and narrow, the tip particularly so; costa very 

 strongly arched near base ; outer margin evenly curved to nervure lb, where there 

 is a sharp, short, tooth-like projection ; upper discocellular greatly curved inwards, 

 the lower nearly straight. On the underside of forewing there is no patch of long 

 hairs on the lower half of cell. Larva with subdorsal row of eyespots developed on 

 abdominal segments 1-8, those on segments 3-8 poorly developed (Weismann, 

 Studies ill. Theory of I te-scent , transl. p. 195) — Lilina, n.g.,piiiaftrina{ = bigecta = silhe- 

 tcnsis :^ intcrsrcta) [type of genus] . 



Head large for the size of the moth. Antennas very strongly hooked, the hook 

 very fine and pointed, and terminating in a long bristly hair. Abdomen slender. 

 Palpi rather short. Legs fairly long and slender, with well developed spines on all 

 the tibiiu ; the spurs long, but not so stout as in Daphma. Forewing with costa 

 straight, to well beyond nervure 7, then flatly curved to apex. Outer margin slightly 

 excised to nervure"?, thence flatly curved to tornus. Inner margin considerably 

 upcur%'ed immediately beyond tornus and downcurved before base. Hindwing 

 rather long and narrow, and only very bluntly pointed ; the costa rising abruptly 

 from base to about the length of cell, flatly curved to just before apex, and thence 

 very strongly arched. Outer margin curved to nervure 3, and thence to nervure lb, 

 curved inwards. Nervui-es 6 and 7 stalked. Discocellulars almost in straight line — 

 Bffiia, n.g., torenia (type of genns). 



Head long, very projecting ; antennse with a long produced tip. Forewing 

 with costa slightly arched to well beyond nervure 7, thence strongly curved to apex 

 which is very acute and prolonged. Outer margin greatly excised to nervure 6, 

 where it is bluntly angled, thence straight to nervure 3, again bluntly angled and 

 straight to tornus. Inner margin greatly upcurved from tornus and strongly down- 

 curved before base. Hindwing broad and short ; the costa boldly curved and 

 immediately before apes particularly so. Nervures ft and 7 from upper angle of 

 cell ; nervure 8 almost evenly curved from base. Legs short and stout with 

 moderate spurs. Spines on tibiae weak and obscured with hairs. Abdomen short, 

 stumpy, with a broad fan-shaped anal tuft in t? — Indiana, n.g.,bha(ja(tyipe of genus). 



Htructurally this genus {Indiana) appears to agree rather with the 

 Philampelids than the Daphnids. It may be the Old World represen- 

 tative of the Philampelids (Kaye, in litt.).

Field Work from Middle of April to Middle of May. 



1. — Spihnota pauperana may be taken in its very restricted haunts 

 during the latter part of April, and, in backward seasons, until the 

 middle of May. It is not a free flier, and is most readily obtained 

 by beating rose, on the bloom of which its larva feeds. A fairly mild 

 and calm day must be selected when working for the species, as with 

 an east or north wind it is well nigh impossible to induce a moth to 

 move. 



2.— Catkins of sallows and aspen, which easily tall when the bushes 

 or trees are shaken, should be collected, and will, in due time, give a 

 'varied series of Grapholitha nisana. The catkins should be placed in
