CICINDELIDiE. 



by a narrow and very deep fissure, very sharp ; maxillary palpi 

 with the third joint rather long in both sexes, strongly clavate, 

 the last very short, smaller, subglobose or securiform in the male, 

 narrower in the female ; head with the forehead between the eyes 

 very widely, deeply, and roundly excavate, with the posterior 

 margin of the excavation semicircular, subcarinate, vertex (behind 

 eyes) very short. 



Colly rides spurice, Chaudoir, op. cit. p. 493. 



Labrum with the central teeth obtuse, and the external tooth 

 on each side separated from the rest, sharp ; maxillary palpi with 

 the third joint a little shorter than the last, the latter sub-elongate, 

 ovate ; labial palpi with the last joint securiform, more dilated in 

 the males. Head with the forehead between the eyes narrowly 

 impressed, bistriate, the vertex broadly pulvinate or cushion- 

 shaped, and not sloping abruptly downwards. 



The characters, however, of the teeth of the labrum or of the 

 palpi are not of much value, as they are very variable in different 

 species, and Dr. Horn, who raises these groups into subgenera 

 (Archicollyris and JSfeocollyr'is) omits them in his description and 

 rightly lays special stress on the large size of the species of the 

 first subgenus, and on the difference in the shape of the vertex 

 and front. In these latter points there are no intermediate 

 forms, and, as they appear certainly to be distinct genera, and 

 Collyris lonf/icollis, is the original type of the genus, the name 

 Colly ris must stand for the species contained in Dr. Horn's 

 ArcTiicollyris, and FeocoJlyris, Horn, may be adopted for the rest 

 of the genus. 



The genus, as now constituted, contains four species, all of 

 which occur in India : they may be roughly separated as follows, 

 but are very hard to distinguish in two or three cases : — 



I. Elytra sometimes rugose, but not dis- 



tinctly plicate in the centre. 



i. Pronoturn strongly constricted at 



base longicollis, F., p. 225. 



ii. Pronoturn not strongly constricted 



at base. 



1. Shoulders oblique. 



A. Elytra longer, less regularly 



punctured dohrni, Chanel., p. 225 . 



B. Elytra shorter, more regularly 



punctured brevipmnis, W. Horn, p. 22G. 



2. Shoulders rectangular brevipennis var. subtilesculpta, 



II. Elytra, as a rule, with strong plicre [W. Horn, p. 226. 



in the centre * mniszechi, Chaud., p. 227. 



* In some cases these are absent, and the species may then be distinguished 

 by the more ovate and dilated central portion of the pronoturn, and other 

 minor characters.
