PHAUDA; PSEUDOPSYCHE. By Dr. K. Juiujan. 5 



2. Genus: Phailda Walk. 



Body rouLjli-haiiy, abdomen of & with loiii; tufts of hairs at the apex of the abdomen. Ocelh ab- 

 sent. Palpus and tongue present but small. Antenna setiform, pectinated in a", the pectinations short and 

 those of each segment fused together to form (in ventral aspect) an angle, in ? non- pectinate. Foretibia 

 with spur: mid- and hindtibiae with a pair of very short apical spurs. Wings elongate; forewing with 4 

 or 5 subcostals, all from the cell, or 4. and 5. stalked; costal vein of hindwing separate from cell, connected 

 with the subcostal vein by a bar proximally of apex of cell. — Larva on Ficus and Terminalia, anteriorly 

 liroader than posteriorly, with a brown dorsal stripe which is anteriorly dilated, sides white or yellow. 

 Cocoon hard. Ijarrel-shaped, yellow, with brown and red stripes. — A genus of the Oriental Region, re- 

 presented in tlie Palaearctic fauna by three species occurring in China. The perfect insects resemble the 

 Coleopterous genus Lijai^: when touched they curve the abdomen ujiwards, the anal brushes projecting like 

 a pair of forceps, reminding one of earwigs. 



P. triadum Walk. {— fortunei U.S.) (la). Reddish yellow, the centre of the upperside of the alt- triadum. 

 domen, the long apical tuft and a large patch at the apex of the wings black.*) — North China; Kiukiang, 

 found in June. 



P. pratti Lrech (la). Body black; abdomen and underside of thorax golden yellow. Foiewm^ pratii. 

 orange-yellow, distally brownish grey, the apex being pale grey. Hindwing semitransparent, distal half 

 black. — I-chang am Yang-tse-kiang, where Pk.mt discovered the cf in July, also at .Aloupin and Wa-shan, 

 \Vest China, in June and July. 



P. lanceolata nor. ^pec. (la). Body reddish yellow, frons, forecoxa, a stripe on abdomen and most lanceotata. 

 likely also the antenna black. Forewing long, without indication of an anal angle, brownish black, extreme 

 base yellowish red, 2. and 3. radials on a short stalk. Hindwing transparent, with darker edges, 2. and 3. 

 radials on a long stalk. — I-chang, one cT (without antenna) in the Tring JIuseum. 



3. Genus: P»ieuclo|>syche Oberth. 



Body long-hairy. Tongue and ocelli absent. Palpus rather long, rough-hairy. Antenna setiform, 

 long-pectinate in o^, the pectinations without scales, in ? the antenna very thin, each segment produced 

 into a point on underside. Foretibia without spur; mid- and hindtibia with a pair of short apical spurs. 

 Wings distally transparent, sparsely clothed with small scales. Forewing with 5 subcostals, the 3., 4. and 

 5. stalked, the 5. nearest the cell, the 2. and 3. radials close together, both median branches proximally of 

 cell-angle; costal vein of hindwing anastomosed with the cell, except base, becoming free proximally of 

 apex of cell, 1. radial and subcostal on a long stalk, 2. and 3. radials from a point or on a short stalk. — 

 Amurland and West China. 



P. dembowskii Oberfh.**) (Ibi. Body black, the hairs mostly yellowish grey, the mesothoracical rfmfioi^'s- 

 tegula and the abdomen below at the sides and above at the apex red or yellow. Wings transparent, veins *"■ 

 black, base yellowish or red. Two forms are known. — The form described b}' ObekthCk is from Askold; 

 the base of the wings and the abdomen are yellow. — The other form, oberthueri Strp-. (lb), has these oberthueri. 

 parts red. Occurs on the mainland in May and June near Wladiwostock, Raddefka and Chabarofka, being 

 doubtless more widely distributed in the southern districts of Amurland. 



P. yarka Oberth.{\b). Appears to belong here according to the tigure. Smaller than the preceding j/ar^a. 

 species. Head, thorax, apex of abdomen and base of forewing pale yellow. — Ta-tsien-lu, found in May. 



B. Subfamily: Chalcosiinae. 



Tongue and palpus present; the latter separated from the eye by a geiial stripe which is usually scaled. 

 The stripe of scales bordering the eye posteriorly is broad, bearing above thin erect hairs. Frons usually strongly 

 convex, prominent. Antenna in cf and ? pectinate, at least at the apex. Foretibia without spur; mid- and hind- 

 tibiae with a pair of short spurs at the apex. Anal segment of ? mostly modified into a long ovipositor. — The 

 species of this cential subfamily of Zygaenidae are nearly all more or less metallic green or blue, being mostly 

 marked with red. yellow or white. This subfamily contains very diverse-looking forms, which, however, are all 

 easily distinguished "from the Zygatninae by the absence of the foretibial spur. The species are partly verj' variable, 



*') This species, whicli I found in China in September, resembles, when crawling about with the wings closed, exactly 

 a bug of the Hemipterous family Lygaeidai. The large black apical patch of the wings represents the membranous portion of 

 the Hemipterous wings. The same applies to PhaiKhi .yKmatreimls M'ulk:, according to information received finni Hofrat B. Hagex. 

 — Seitz.
