404 BKITISH BUTTERFLIES. 



that they were sikkima, Moore, comparison with the types in the 

 Moore coll. at the British Museum proved the surmise to be correct. 

 Moore also described, in 1883, a species with very similar facies, but 

 quite distinct genitalia, called jynteana. De Niceville's jynteana 

 (Butts. India, in., pp. 104-5) appears to be a mixture of Moore's sikkim a 

 and jynteana, and even Moore himself, later, failed sometimes to appreci- 

 ate the distinction, for, in the Brit. Mus. coll., there is a sikkima labelled 

 jynteana by Moore himself, whilst in the Moore coll. there are several 

 sikkima correctly placed under this name, but also several others 

 mixed up with jynteana, which suggests that Moore did not later 

 maintain his grip on the differences when dealing with the two insects. 

 As a form of C. argiolns, it is very far from any other race, in 

 the very broad dark border to the forewings (and sometimes the 

 hindwings) and in the discal streak; there is considerable varia- 

 tion in breadth of this border, some specimens being nearly as 

 dark as C. puspa. [C. jynteana appears to be without the discal 

 streak, and also without the white shading on the forewing ; at any 

 rate, these are not usual, whilst in sikkima the discal streak is 

 rarely absent, and white suffusion is not uncommon.] The undersides 

 of sikkima and jynteana are very close ; in the former the discal row of 

 four spots is straighter, and the spots themselves more in line ; in 

 C. jynteana there is a greater tendency to their being en echelon, and 

 the costal one is a little further in, making the distance between this 

 one and the separated costal spot less than it is in sikkima (argiolns). 

 The difference is, however, too slight to be noted except by comparison 

 of specimens, and not by absolute description. In spite of this super- 

 ficial similarity of wing-markings, the $ appendages have a very 

 distinct and characteristic structure in C. jynteana, which is very different 

 from that in sikkima, where they can be detected to differ in no way 

 from those of C. argiolus (Chapman). 



6. var. albocaeruleoides, n. var. — Another Indian form of G. argiolus very 

 much resembles G. albocaeruleus, and is mixed with that species in the British 

 Museum ; its genitalia are distinctly those of C. argiolus. It does not appear to 

 be a named form, and might very properly be called albocaeruleoides (Chapman, 

 in litt., 12, II. 1908). 



Chapman, besides having discovered sikkima, Moore, and victoria, 

 Swinh., to be forms of C. argiolus, observed that he had two other 

 specimens, without data, which he was unable to identify with any 

 descriptions, but which happened to agree with a specimen in the 

 South Kensington Museum Coll., labelled albocaeruleus, and mixed 

 with that species. He says : " These examples much resemble C. albo- 

 caeruleus, but, perhaps, are even more like C. marginata ; they are, 

 however, quite distinct from both these species, and are, in fact, a 

 form of C. argiolus. From the specimen that was mixed with albo- 

 caeruleus, I propose that this be called albocaeruleoides. It is, struc- 

 turally, as far from C. albocaeruleus and C. marginata as any two 

 species in the genus can be. The specimens resemble sikkima more 

 than they do albocaeruleus ; they differ from it in a wider dark border, 

 a large white patch in the middle of the wing and in wanting the 

 discal streak. The dark wing-margin is of the pattern of sikkima or 

 C. puspa not of 0. albocaeruleus. The var. albocaeruleoides is a very 

 parallel form to the Central American var. gozora."
