332 Records of the Indian Museum. [Vol. XIII, 



the whole ' Legion' is characterized by a tendency to originality in 

 colouring. 



The grouping of the species adopted by Selys, which depends 

 on the position of M3, RS, relative to the subnodal cross-vein, 

 seems to be a natural one as it is supported by the geographical 

 distribution of the species. 



Thus the species agreeing with C. renifera in this respect are 

 all found in the Himalaic mountain complex and its outlying spurs; 

 those akin to C. memhranipes are more definitely Malayan with 

 their headquarters in Borneo. In the accompanying table I have 

 attempted to give the chief characteristics of the C. renifera group 

 so far as they are known to me. The table is, of course, largely 

 compiled from Dr. Eis' article on species of the genus {Supplementa 

 Entomologica, No. i, 1912, pp. 61-67; Berlin). 



Martin has recorded C. octogesima (Selys), C. renifera {Selys), 

 and C. membranipes (Ramb.) from Tonkin (Martin, Mission Pavie 

 (Nevropteres), 1904). I think it possible that the Tonkinese form 

 of C. renifera, at any rate, may prove to be distinct from species of 

 the type locality. 



Table. 



Mg proximal to nodus, MS distal. 



Costal side of quadrilateral of fore-wing about one-third shorter than 

 anal side. 

 Space between quadrilateral and subnodus normally with two 

 cross-veins {i.e. 3-celled). 



a. Costal side of pterostigma about one-third shorter than anal 



side. 



(J segments 9, 10 blue ; thorax of ^ and J similar. 



C. bracliysticta, Ris. — Philippine Is. 



b. Costal and anal sides of pterostigma sub-equal. 



i. (^ segments 9, 10 orange; anal appendages orange; 

 thorax of ^Jand $ similar. 



C. flavicaiida, Ris. — Formosa. 

 ii. (^ segments 9, 10 black (marked with blue), anal ap- 

 pendages black ; thorax of $ with complete antehumeral 

 band. 



C. ei'ici, n. sp. — Malay Peninsula, 

 iii. (^ segments 9, 10 largely blue, anal appendages brown ; 

 thorax of j with complete antehumeral band. 



C. simillima, n. sp. — Malay Peninsula. 

 Costal side of quadrilateral of fore-wing about one-fifth shorter than 

 anal side. 



I . Space between quadrilateral and subnodus normally with one cross- 

 vein. 



C. himaculata, Laidlaw. — Assam. 

 (? =: C. dtdynia, Selys). 

 II. Space between quadrilateral and subnodus normally with two 

 cross-veins. 



i. ^ segments 9, 10 and anal appendages blue ; thorax of $ 

 with narrow antehumeral band. 



C. cyanomelas, Ris. — Formosa, 

 ii. ^ segments 9, 10 (adult) and anal appendages black ; thorax 

 of $ with complete antehumeral band. 



C. renifera (Selys). — Himalaya. 



A specimen in the British Museum from the Chin Hills labelled 

 Coeliccia didyma is certainly quite distinct from C. himaculata. I
