prevails on the mountains among which the river Eoughty takes 

 its rise near Kenmare, Co. Kerry. Here it would seem that the 

 moorland surroundings and the dark rocks upon which it rests 

 have induced adaptive coloration. I took a large series here to 

 test the uniformity of the pattern, which was remarkable. 



Cidaeia suffumata, Hb. — Generally distributed, and usually 

 abundant. It varies considerably, the median and basal bands 

 being sometimes of a very blackish brown, with a pale trait on 

 the costa ; but usually it is of lighter tint, and somewhat varie- 

 gated with sinuous shading. The whitish bands on each margin 

 of the median dark band are often darkened with fuscous, a 

 transition stage to the var. piceata, St., which I have not taken.

 cheeks broad, ami produced beneath into a right angle; mandibles lung and 

 slender, ferruginous at tip, tuberculate at base, and produced beneath at 

 the base into a prominent tooth, deeply notched within at some distance 

 from the tip. Face and front dullish, clypeus strongly and quite closely 

 punctured, area in front of the ocelli striate ; antennas long, reaching 

 to metathorax, wholly dark. Thorax dull, with a minutely roughened

 tegulas shining piceous ; wings hyaline, iridescent, the apices faintly 

 dusky; nervures and stigma brown, the stigma very dark; second sub-

Near to A. mandibularis, Eob., but that is smaller (8 mm.), 

 with sparsely punctured clypeus and honey-yellow nervures. 

 A.fragilis, Sm., differs at once by the shining thorax and pale 

 testaceous nervures. A. nigrihirta (Ashm., as Cilissa) is also in 

 some respects similar, but has not the peculiar head-characters
