DOLBINA; DOLBINOPSIS; KENTROCHRYSALIS. By Dr. K. Jordan. 237 



6. Genus: I>oll>iiia Stgr. 



Tliorax stouter than in the following genera; the abdomen above more strongly spinose and beneath 

 furnished with weak spines. The antennae stout, gradually pointed distally, also in the $ with lateral grooves 

 and prolonged cilia. Fore and mid tibiae without spines, spurs short, hind tibia with 2 pairs, fore tibia with- 

 out apical thorn, pulvillus present, paronychiuin with two pairs of lobes on each side. — Larva and pupa (of 

 exacta) according to Graeser so like those of ocellata that they can hardly be distinguished. 



One Indian and two Palearctic species are known as yet. They are very similar in markings and colour- 

 ing, but are easily distinguished by their structure. Upperside of body and wings greyish black, often greenish ; 

 abdomen with a dorsal row of black streak-spots and black lateral spots; underside of body lighter. Forewing 

 above variegated with white, two parallel proximal lines and several discal ones dentate and black ; a discocel- 

 lular dot white, hindwing almost uniformly greyish black, lighter at the anal angle. Sexes similar. 



D. tancrei Stgr. (36 e). Abdomen beneath with large black spots in the middle of the segments. — tamrei. 

 Amurland and Japan; some of the specimens before me were caught in June and August. 



D. exacta Stgr. (= tancrei Stgr. pt., inexacta Fixs. nee Walk.) (36 e). Abdomen beneath with small exacta. 

 black central spots. Larva found by Graeser on Syringa and Fraxinus. Two broods annually; the moth in 

 the spring and from August onward. — Amurland, Japan, Corea and Central China, more abundant than the 

 preceding species. 



The third species, D. inexacta Walk., occurs in North India, and in the North- West extends close to the 

 Palearctic Region. It is larger than exacta and tancrei, and has veiy large black spots on the underside of the 

 abdomen. 



7. Genus: l>4»ll»iiio|>KiK ^.rf^ J- 



A reduced off-shoot from Dolhina. Palpi still smaller, fore tibia with naked end-thorn; pulvillus 

 absent, paronychium just indicated; fore and middle tibiae without spines; hind tibia with two pairs of very 

 short spurs; subcostal and upper radial of hindwing separate. — One .species. 



D. grisea Hamps. Markings and colour almost entirely as m the species of Dolbina, from which grisea grisea. 

 is easily distinguished by the apical thorn of the fore tibia. Only a few ^^ known. ■ — Kulu, North-West 

 India (British Museum). 



H. Genus: Keiitroelir^'salis Stgr. 



Thorax slenderer than in Dolba, conical. Tongue quite short and weak, with long cilia at the inner 

 edge of each half . Palpi small, especially in the $, the joint between segments 1 and 2 visible (bare). Antennae 

 long, in ^ and 9 with prolonged cilia, which are however much shorter in the $ than in the (^, the seg- 

 ments slightly widened laterally. Tibiae without spines; spurs short, hind tibiae with two pairs; pulvillus 

 and paronychium present. — Larva granulose as in Smerinthus, with conical head. Pupa with a few high and 

 sharp humps on the underside. — A purely Palearctic genus with three species. 



K. streckeri Stgr. (= davidis Oberth.) (36 e). Head, thorax and forewing grey, abdomen and hindwing streckeri. 

 more brown, thorax above striped with black, abdomen with black dorsal line of spots and black lateral spots. 

 Forewing with a proximal and a discal pair of brown-black dentate transverse lines, a white discocellular dot, 

 black longitudinal discal stripes, which are sometimes absent, and a black oblique apical line. Hindwing 

 uniformly brown, paler towards the base and at the hind margin. Fringes of both wings chequered with black 

 and white. Anal sternite of (S s^ort and broad, slightly emarginate, harpe with broad bipartite process directed 

 dorsad and long narrow horizontal apical process. Larva on Fraxinus and Ligustrum, fairly common, e. g. 

 near Vladivostok, according to Graeser similar to that of «S'. ocellata. The very peculiar pupa is able to 

 crawl forward fairly fast with the help of the pointed abdominal processes by moving the abdomen quickly from 

 side to side (Graeser). Amurland. 



K. consimilis R. d- J. (36 e). In shape and markings similar to .streckeri, the inner transverse lines consitnilis. 

 of the forewing more strongly developed and ending posteriorly in a blackish smear which is prolonged basad ; 

 the outer transverse lines are less distinctly dentate than in streckeri. In structure, however, consimilis is more 

 closely allied to the following species. Anal sternite of (J deeply cleft; harpe longer than the clasper, dorsally 

 with several short processes, apically with two. — Japan, on the Main Island, in August, and certainly also in 

 the spring from hibernated pupae. 



K. sieversi .-l/^j/^eV. (37a). Larger than the preceding species. The large black spot which is found sieversi. 

 on the upperside of the antennae of those species is only slightly indicated in sieversi. Body and forewing above
