Insects. 



me a very elaborate description of E. innotata, and has pointed out the few distin- 

 guishing characteristics of E. fraxinata. These I subjoin, together with my own de- 

 scriptions of the respective larvae. These latter are much more dissimilar than the 

 larvae of A. Psi and A. tridens. 



Eupithecia innotata, Hubner. 

 Expanse of anterior wings in a full-sized specimen, 10 — 10^ lines. Fore wings 

 gray, with a slight brownish tinge, mottled with brown and black scales. Disk some- 

 what paler than margins. Along the auterior margin a series of about twelve irregular- 

 sized black spots arranged generally in pairs, and forming the anterior outlines of the 

 paler undulated strigae which run across the wings. From the base to the middle of 

 the anterior margin these spots have an outward direction, but from the middle to the 

 tip they are directed obliquely towards the base of the wing. In the middle of the 

 wing closing the discoidal cell is a small transverse black spot; the median vein be- 

 tween the base and the first branch is marked with one roundish and three oblong 

 miuute black spots. The branches of the median vein, as well as the two disco-cel- 

 lular and the subanal veins, are also faintly marked with blackish spots, those on the 

 first branch of the median vein being the most strongly marked. All these spots in- 

 dicate the direction of the pale obliquely undulated strigae. Of these one near the 

 base, two running across the middle of the discoidal cell (strongly elbowed near the 

 middle of the cell), two beyond the middle of the wing (strongly elbowed towards the 

 fore margin), and one subapical (strongly elbowed near the anal angle, and formiug a 

 well-marked W opposite the apical angle) are the most conspicuous. Other strigae 

 are faintly and indistinctly indicated. The outer portion of the wing has also a series 

 of small dark lines running from the margin towards the disk between the veins. The 

 outer margin itself is formed by a dark line. Fringe pale, outer portion dark, near the 

 base a dark line. Hind wings paler than fore ones, especially on the disk. Anal 

 portion darker, varied with short transversely undulating strigae. At the beginning of 

 the disco-cellular vein a very minute dark dot. Beyond the middle of the wing a 

 denticulated dusky striga, followed by a whitish one commencing at the anal angle, 

 beyond which the outer portion of the wing is dusky. Fringe pale at the base, darker 

 on its outer portion, with a dark line near the base dilated into dark dots opposite the 

 extremities of the longitudinal veins. Body griseous, slightly varied with darker 

 scales. On each abdominal segment a small dark dot. Antennae slightly luteous. 



Eupithecia fraxinata, Crave. 

 Expanse of anterior wings in full-sized specimen, 10| lines. Fore wings of a 

 much more uniformly brownish gray. Black markings and pale undulating strigae 

 similar in number and position to preceding species, but always very faint and indis- 

 tinct. The white subapical strigular W barely visible, or very indistinct. Fringe 

 much more uniform in colour than in E. innotata. Posterior wings much darker on 

 the disk ; anal portion much less strongly marked, especially towards the body ; the 

 dark and pale subapical strigae can in fact only be traced with the greatest difficulty, 

 though their place is indicated by the somewhat more decided markings at the anal 

 angle. 



Larva of Eupithecia innotata, Hubner. 

 Ground colour pinkish gray. Oeutral dorsal line rusty, or dull purplish brown, 

 connecting a series of well-defined top-shaped blotches of the same colour. Dorsal
