Head sub-orbicular, clypeus broad and rotundate, with a 

 pitchy margin, from which arise on each side a tongue- 

 shaped oblique black fascia, temporal fossae deeply ex- 

 cavated, with a quadrangular black patch in the centre, 

 lateral margin sinuated at the base, with two black spots, 

 occiput sub truncate and black; eyes prominent and black; 

 antennae pale yellow, the second joint very long, subcla- 

 vate ; prothorax small, transverse, anterior margin rotun- 

 date and black ; metathorax as broad as the head, lateral 

 margin round, posterior produced in the centre, and sub- 

 angular, anteriorly, with two broad black fasciae ; abdo- 

 men large, oval, pale yellow-white, the first segment large, 

 with a pale ash-coloured humeral patch, the remainder 

 small and equal, with transverse sinuated fasciae, margined 

 with black ; legs long ; femora and tibiae, with the superior 

 margin black. Length 1^. 



Parasitical upon the Domestic Fowl (Gallus domesticus), 

 though not very abundant. 



Three other species recorded by Nitzsch and Burmeister 

 I have little doubt are natives of the British Isles. The first 

 G. rectangulatus upon the Peacock on the authority of the 

 former; the second G. microthorax upon the Partridge 

 also by the same author, the specific characters of which 

 are not given ; and the third G. astrocephalus upon the 

 Quail, which Dr. Burmeister in his Handbook of Entomology 

 thus describes : "Pallidus, occipitearcuatoV-dentato, macula 

 fusca trioona in quovis arcu; segmentis abdominalibus utrin- 

 que lima rcpando-derttata. Long, f 1 ." For the two former 

 I have searched in vain, for the latter I have never had the op- 

 portunity, for the want of specimens of the Quail to examine.
