310 HIMEROPTERYX; PHALERODONTA ; NADATA. By Dr. K. Grunbeeg. 



blackish tuft of hair. Forewing dark greyish brown, with siibbasal, pre- and postdiscal dentate black-brown 

 bands; fringes black-brown, spotted with grey. Hindwing greyish brown. — East Turkestan (Yangihissar). 



34. Genus : Himeroptorj'x Stgr. 



(J-antenna with long pectinations, which are shorter towards the apex; $ not known. Palpi obliquely 

 upturned, long-hairy, extending beyond the hair of the frons only with the short end-segment. Proboscis vesti- 

 gial. Eyes naked; ocelli absent. Thorax and legs with very long dense woolly hair, abdomen with shorter smooth 

 hair. Hind tibia with long mid- and end-spurs. Forewing relatively very broad, triangular, apex rather sharj), 

 distal margin steep, slightly undulate, hind margin with a broad pointed tooth of scales in centre; veins 6, 7, 

 8, 9 stalked, 6 close beyond cell, 10 from the cell, anastomosing with the stalk of 7, 8, 9 and thus formmg 

 a narrow triangular areole. Hindwing broad, rounded, veins 6 and 7 stalked. 



The remarkably broad forewing with their steep distal margin at once recall Geomctridae, especially 

 Himera and Crocallis. Staudinger, who considered the genus a connecting link between the Notodontids and 

 Geometrids, has already drawn attention to this similarity and expressed this view in the name chosen for the 

 genus. So far a single species has been found in East Siberia and only a few specimens obtained, the species 

 having hitherto remained one of the greatest rarities. 



miraculosa. H. miraculosa Stgr. (47 c). Thorax dark brown, abdomen yellow-brown. Forewing yellowish grey 



or yellowish brown, with a broad dark red-brown median band not correctly represented in the figure which 

 commences at the lobes of scales in the centre of the hind margin, is anteriorly devidsd by a large rectangu- 

 lar pale discal spot and does not reach the costal margin ; basally to this band a subbasal similarly coloured 

 band which is only distinct at the hind margin; distally 2 transverse rows of similarly coloured spots, of which 

 the outer row placed close to the di.stal margin is strongh* obsolescent. Hindwing agreeing with the forewing 

 in the ground-colour, without markings. — ■ Amurland (Raddefka): lately also sent from the Su-chan, east of 

 Vladivostok. Also found in Japan. 



35. Genus: PliaIero<l4»iila Stgr. 



Antennae slightly dentate and ciliate in (^, setiform in $. Palpi of ^ distinctly projecting beyond frons, 

 segment 2 long-hairy, 3 porrect and smoothh^ scaled; shorter in $. Proboscis feebly developed. Thorax with 

 long and dense woolly hair, abdomen of $ with a long and very densely woolly anal tuft, which is less dense 

 in (5". Forewing rather broad, costal margin straight to near apex, the latter rounded, distal margin moderately 

 strongly oblique and very slightly undulate, hind margin somewhat excised at the bass, with a broad but very 

 short lobe of scales. 



iombycina. P. bombyclna Oberth. (4:7 c). Body light greyish yellow. Forewing with slight brownish tint, quite 



straight prediscal transverse line and strongly curved postdiscal one, both dark brown, the latter continued 

 over the light grey-yellow hindwing as dark arcuate Ime. Ussuri-district. — GR.\ESERhas described the early stages. 

 The egg hibernates. The larvae feed exclusively on Oak, being gregarious luatil pupation, but without a com- 

 mon web. They also resemble Phalera bucephala in facies. They are black, with rather large glossy black head 

 bear single stiff hairs and on each segment some cherry-red spots. They rest with raised fore and hind parts, 

 also as the larvae of Ph.hucephah. Pupation at the foot of the trees in a hard, leathery cocoon loose silk-threads 

 intermixed with lumps of soil forming together with the cocoon a large clod. The cocoon itself, however, is 

 disproportionately small as compared with the larva. Pupae June — July, the moths in the same autumn, 

 early in October. 



36. Genus : ETatlata Walk. 



Antennae in .^ pectinate to two-thirds, the rest dentate, in ? simple, setiform. Palpi obliquely upturned 

 to half the frons, densely and smoothly scaled, the short .?itump-liko end-segment distinctly marked. Eyes 

 naked. Thorax with long and dense, but smooth hair, and with a high, erec't, laterally compressed crest of scales. 

 Legs with long dense hair, abdomen also rather long-hairy. Hind tibiae with rather short but strong mid- and 

 end-spurs. Forewing elongate, but relatively broad, costal margin rather strongly convex in distal half, distal 

 margin moderately oblique and undulate, more strongly angulate at veins 6 and 4, but less projecting at vein 5, 

 so that there is a broad sinus between veins 6 and 4; hind margin usually with a moderately large lobe of 

 scales in the centre; vein 6 together with the stalk of 7, 8, 9 from upper cell-angle, 10 from cell, anastomosing 

 with 8, 9 beyond 7 and forming a large areole. Hindwing broad, rounded, veins 6 and 7 stalked. — The genus 

 occur.^ also in North America besides Japan, East Asia and the Himalaj^as. 



cristata. N. cristata Butl. (47 b). Head, collar and hairs of legs whitish grey. Thorax light greyish brown 



with a slight reddish tone and also strongly intermixed with white. Abdomen and hindwing light ochreous 

 brown. Forewing ochreous to grey-brown, the central area between the bands always more or less distinctly
