The dift'erence between this genus and Ih/loicus is very slight in the imago- 

 stiite, the tongue and palpus being shorter resp. smaller tlian in the luost reduced 

 species of Ilyloicus. The larva and pupa differ, however, essentially. 



(??. Antenna about two-fifths {S) or three-eighths (?) the length of the 

 forewing, thickest near base in c?, distinctly incrassate distally in ?. Spines of 

 legs not i)roiuiuent ; foretibia with a few apical and lateral spines, one apical spine 

 soniewliat prolonged, midtibia with dispersed spines ; spurs short, long mesotibial 

 one about one-third the length of the first tarsal segment ; mesotarsus without 

 comb; the first segment of the tarsi as long (or nearly) as the four other -segments 

 together ; paronychium very small, without lobes. 



c?. Sexual armature somewhat variable individually. Tenth tergite (PI. 

 XXVIIl. f. 28) slender, curved, i)ointed ; sternite elongate, rounded at end, somewhat 

 triangular. Clasper sole-shajied ; harpe (PI. XXXIX. f. 12. 13) ending in a single 

 process, which is somewhat curved away from the plane of the clasper, its upper 

 margin is dentate distally and is continuous with the broad subdorsal fold of 

 the clasper. Penis-funnel with a three-sided, pyramidal, solid process ventrally 

 (PI. XXXIX. f. 12. 13), the sides of which are more or less concave, while the 

 edges are sharp ; penis-sheath (PI. XXVIIl. f. 51) ending in a triangular, pointed, 

 slightly curved, flat, proximally concave, process. 



? . Vaginal plate rounded distally, flat, the sides slightly incrassate ; mouth of 

 vagina proximal. 



Larva with longitudinal markings, head triangular (except in first stage) ; no 

 horn. — Food : Coniferae. 



Sheath of tongue of pupa not free, reacliing end of wing-cases. 



Hub. Nearctic Region. 



Four species, of which two {halicarniae and pineuni) require closer examination. 



a. Projiortion between width and length of forewing 



about 42 : 100 b. 



Forewing proportionally much broader . 122. L. halicarniae. 



b. Forewing scarcely with traces of markings ; with- 



out discal streaks ...... 120. L. pineum. 



Forewing with transverse lines, sliarply marked, 



mesothoracic tegula whitish at end . 121. Jj. bombi/coides.

marked, mesothoracic tegula not whitish at
