The difference between this genus and Hijloicus is very slight in the imago- 

 state, the tongne and ])alpns being shorter resp. smaller than in the most reduced 

 species of Ifyloicus. The lavva and pupa differ, however, essentially. 



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

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

 legs not prominent ; foretibia with a few apical and lateral spines, one apical spine 

 somewhat prolonged, midtibia with dispersed spiues ; 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 ; paronychiuiu very small, without lobes. 



S. Sexnal armature somewhat variable individually. Tenth tergite (PI. 

 XXVIII. f. 28) slender, cnrved, pointed ; sternite elongate, rounded at end, somewhat 

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

 process, which is somewhat cnrved 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 tliree-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. XXVIII. 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 pro.\imal. 



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

 horn. — Food : Coniferae. 



Sheath of tongne of pupa not free, reaching end of wing-cases. 



Hub. Nearctic Region. 



Four species, of which two {halicKi-nide and piniuim) require closer examination. 



a. Proportion 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, sharply marked, 



mesothoracic tegula whitish at end . 121. L. bombycoides. 



Forewing with transverse lines, less strongly 



marked, mesothoracic tegula not whitish at 



end 119. L. conifer arum. 



110. Lapara coniferarum.
