 meister Handbuch, ii. pt. ii. p. 43-2. spe. 1. 



Head bright chestnut ; clypeus convex, temporal margin 

 sinuated anteriorly, with a black band before the antennae, 

 posteriorly produced and acutely angular, occiput truncate, 

 with a deep chestnut margin, vertex depressed ; eyes pro- 

 minent, large, ash-coloured ; antennae pale, the first joint in 

 the male comparatively small and conical, second long and 

 clavate, third securiform, fourth and fifth small ; prothorax 

 transverse ; metathorax sub-triangular, lateral margin with 

 a broad deep chestnut hook-shaped band, posterior angle 

 acute ; abdomen pale, yellow, and hairy, obovate, or ob- 

 tusely truncate, lateral margin with a broad ferruginous 

 band, and a transverse pitchy line at the sutures, segments 

 well defined ; legs pale, ferruginous, with a dark chestnut 

 band on the superior surface. Length f. 



I have seen only two males of this species, which I took 

 from two different specimens of the Common Partridge 

 ( Perdix cinerea). I have ventured to place it as the Dispar 

 of Nitzsch and Burmeister, though not without doubt, as to 

 the identity of the species. The peculiar form of the third 

 joint of the antennae would have led me to suppose it was 

 the G. securiger of the latter author, had that species been 

 parasitical upon a British bird, but as the Perdix petrosa is 

 given as its nidus, which has never occurred in Britain, its 

 identity with the latter is barely probable.
