34 XENOCHLORODES. By L. B. Peotjt. 



simonyi. E. simonyi Ebl. (= divincta Holt-White = pallida Warr.) (3c) has the wings long and narrow, 



recalling the genus Ehadinomphax of South Africa. The forewing is pale green, without markings; the fringe 

 and the entire hindwing greenish white. Under surface similar. Besides the great difference in shape and co- 

 loration, this species differs from true Eucrostes in the $ antenna, which is merely serrate-dentate, not pecti- 

 nate. Canaries. Mrs. Holt-White records the capture of a i^ on Teneriffe in April, iljing at dusk among 

 cactus plants at about 150 m. The only two specimens which I have before me are a cJ and a $ likewise 

 from Teneriffe, the former bred by Lord Walsingham from an undescribed larva found on Frankenia eri- 

 cifolia on 16 March, the moth emerging on 15 April. 



37. Genus: Xeiioclilorocles Warr. 



Palpus minute. Antenna in c? pectinate, in $ serrate (in nubigena simple). Hindtibia with a single 

 pair of spurs. First subcostal stalked or connate with the other subcostals, running into costal or at least 

 anastomosing, first median stalked, rarely only connate. Hindwing with costal anastomosing with subcostal 

 for the greater part of the length of cell, second subcostal and first median both stalked, second radial from 

 scarcely above middle of discocellulars. Differs essentially from Eucrostes in the strong anastomosis of the 

 costal vein of the hindwing. Consists of only three species, all Palearctic. 



nubigena. X. nubigena Woll. (3 c) differs from the other species in fades, and in some slight details of struc- 



ture, but is certainly congeneric. DeUcate green, with the costal edge narrowly crimson (broadly in basal 

 half beneath), both wings with a curved white postmedian line, usually thick, subdentate, sometimes broken 

 up into spots, a little recalling Comostola ovifera or inojjs. Occm-s only in Madeira, in May and June, fre- 

 quenting the heath-woods of the loftiest elevations, and is strongly attracted by light. 



olympiaria. X. olympiaria H.-Sch. Pale delicate green with an indistinct pale postmedian line and occasionally 



traces of an antemedian. Costal edge yellowish white. Distal part of fringe white. Face reddish. Neigh- 



cremonaria. bourhood of Brusa and some parts of Syria. — cremonaria Stgr. ( = pallida Warr.) is much paler, often nearly 

 white, although showing, when quite fresh, a delicate greenish shade. In such condition the lines are still 

 traceable, but faded specimens appear entirely unicolorous. Syria: about Beyrout and probably elsewhere. 



Uryllaria. X. beryllaria TIfawre (= aureliaria ilfi^Z.) (2e, c?; 2i, $). Nearly related to the preceding and of 



closely similar structure, but at once distinguishable by its beautiful bright emerald-green colour. It is also 

 on an average larger, and has the first subcostal of forewing longer-stalked. Postmedian line removed 

 further from the distal margin, sometimes forming more distinct spots on the veins. Distributed locally in 

 southern Europe, North Africa, Syria and the Taurus Mountains. 



4. Subfamily: Acidaliinae. 



Mostly small, slenderly-built moths, commonly of white, light brownish, ochreous or similar colo- 

 ration, the markings consistmg principally of darker transverse lines. Face nearly always smooth-scaled, usually 

 flat. Palpus usually short (long in some of the Anisodes-gvow^), Antenna in the ^ not infrequently bipec- 

 tinate, but by no means so generally as in the Hemitheinae; in the $ nearly always simple. Hindleg very 

 variable; in the ^ often aborted and without spurs; the number of spurs, if present, varying in the (J from 

 1 to 4, in the $ from 2 to 4, $ often with more spurs than cj. Abdomen not crested, rather slenderly attached 

 to thorax. Forewing usually smooth-margined, all the veins almost invariably present, subcostals usually 

 anastomosing so as to form one or two accessory cells (often called "areoles"), the second subcostal inva- 

 riably anastomosing with or arising ont of the third. Frenulum well developed. Hindwing varied in shape 

 and structure, sometimes more or less contorted in the ^J, costal vein anastomosuag with subcostal at a point 

 near base, then usually diverging rapidly, second radial usually arising from the middle of the discocellulars. 



The eggs are of approximately the ordmary Geometrid form, the length greater than the breadth, 

 the breadth than the height, and usually with one end broader and higher than the other. Some are more regularly 

 ovate, others more nearly cylindrical, others again so much flattened that they have been described as "discs". 

 They are usually attached by one side, but not infrequently a. little tilted, in Acidalia even often attached by the 

 end opposite the micropyle, becoming in position "upright eggs", though still maintaining the shape and 

 proportions of the "flat egg" of Chapman. A very frequent colour-scheme — apparently almost invariable 

 in the typical genus — consists in the presence of irregular spots or blotches of some shade of red. The great 

 majority of the known larvae, excepting yiose of Gosymhia and a few of its allies, feed on low plants, and 

 hibernate in the larval stage. They are comparatively seldom found free, and our knowledge of very many
