PHRIXOLEPIA; COCHLIDION. By Dr. A. Seitz. 341 



is much more delicate, slenderer, the abdomen longer, the forewing broader, and, above all, the palpi longer 

 and upturned, although not approximately so long as in the two previous genera. — Only 1 species is known. 



M. longipalpis Bull. (50 a). Usually smaller than our C. limacodes; the body almost as delicate as in lorxgipalpis. 

 a Geometer, the thorax narrow; the palpi porrect, projecting by more than the length of the head, pointed, 

 without apical tuft. Forewing yellowish browii at the base, apex and the centre of the hind margin, otlier- 

 wise shaded with violet-grey. The hindAving grey, with pale fringes. In facies similar to the somewhat larger 

 Phrixolepia sericea Biitl. from the same country. — • Corea and Japan (Satsuma, Hondo). 



4. Genus : Phrixolepia Bull. 



This genus is purely Palearetie, since invicta Walk, from Borneo certainly does not belong here. There 

 are hardly any structural differences from the next genus, only the forewing is more pointed, with slightly 

 curved distal margin; however, the wing-contour differs more in the two species of Phrixolepia than in no- 

 bilis and Cochl linvicodes. Both species are somewhat larger than the European limacodes and have a slight 

 metallic gloss. Staudinger, however, has already said that the separation of Phrixolepia from Cochlidion 

 is artificial. 



P. sericea Bull. (= Lim. castaneus Oberth.) (49 k). Forewmg bright golden brown, traversed by a. sericea. 

 narrow white band which is proximally dark-bordered and behind cell elbowed at right angles. — Larva 

 probably on Juglans mandschurica, as Korb repeatedly found the species at rest at this tree. Its posture is sim- 

 ilar to that of Cochlidion limacodes, the forelegs being stretched forward, the wings folded together so that 

 the outer margins touch, and the ftbdomen raised. — ■ Distributed in East Asia; in Amurland on the Su-chan 

 and at Vladivostok, on Askold, andin Japan on Hondo and in the Hokkaido; in July, usually not rare. 



P. nobilis Stgr. (49 k). This species, discovered by Christoph in Amurland, appears to be rare. Be- noMlis. 

 fore the marginal area of the forewing there is a dark shadowy band which is traversed throughout its length 

 by a paler Ime. 



5. Genus : Coclllidloil Hbn. (Limacodes Latr.) 



According to the extent adopted for this genus, it contains 5 to 20 species. Only a few forms 

 occur on Palearetie territory. Body and wings everj^where rounded, the forewing with a very long cell which is 

 divided at the apex into 2 lobes by the intracellular vein. $ much clumsier than the cJ. — Larva strongly 

 convex, short wood-louse shape, with but feebly raised subdorsal longitudinal carinae, without urticating hair, 

 with small concealed head. — ■ The (^J fly by day in the sun, the 9? mostly at night. They have only one 

 brood, one of the species being in temperate Europe one of the commonest moths. 



C. limacodes Hufn. (= testudo Schiff., asella Esp., testudinana Hbn., avellana Kirby, sulphurea F., limacodes. 

 funalis Don.) (49k, 50 a). Very variable; the 3" usually chestnut-brown, more or less suffused with russet- 

 black (suffusa), sometimes irregularly spotted with yellow (maculata), the J uniformly yellow like the ? (och- suffusa. 

 racea), mostly with large yellow patch above centre of hind margin (limax Borkh.), or yellowish browii with '"««(?ato.

 of the (J there are three spots on a dark brown ground, one in front of the hind angle, pnother before the ^i<fo. 

 apex and a third m the centre of the oblique median band. $ yellow to brown, the median band only indicated 

 by the brown borders, an oblique line usually runs from two-thirds of costal margin to the hind angle. — • Larva 

 scutiform, semiglobular, bright yellowish green, with a yellow subdorsal and lateral line, the ground between 

 them lighter. In the autumn on deciduous trees, especially high Oaks, on the underside of the large hard 

 leaves of the lowest branches, being difficult to obtain by beating, often falls off with the autumn-leaves in 

 October. It then spins a ro.sy red ovate cocoon, in which it remains in a contracted state until April, when it 

 turns into a chrysalis. The moth appears the end of May and can be beaten from deciduous trees. The (J (J 

 swarm by day in sunshine along the edges of woods, the flight being wild. In Europe from Scandinavia 

 and Livonia to the coasts of the Mediterranean, and from the west-coast to the Black Sea and Asia Minor. # 



Abundant. 



C. christophi G^caes. (49 a). Exactly marked like the $ of limacodes, hut on a bright reddish chestnut- christophi. 

 brown ground. The species, as the figure shows, is considerably slenderer and more delicate, the wings broader 

 in proportion to the slender body, with the costal margin more curved and the apex more pointed. In these 

 particulars christophi approaches in build the much smaller H. asella Schiff. — ■ On the Ussuri, in July; appar- 

 ently not common. 



C. codeti Oberth. (50 a). As large as or larger than testudo, light red-brown to leather-yellow; the mark- eodeti. 

 ings differ from those of the externally similar limacodes in that usually only the proximal border-line of the 

 middle band is sharply marked. — Mauretania. Staudinger's diagnosis "major, dilutior" applies only to some 

 specimens.
