Galesus is characterized by the peculiar form of the antennae, 

 and by the remarkable head and distinct petiole ; and it may 

 be observed that the Psili of Jurine, which are the Diaprise of 

 Latreille, vary from our genus in having the third joint of the 

 antennse long. 



In dissecting this insect, the curious scales vi'hich cover the 

 base of the superior wings attracted my notice; they are thin 

 and moveable, and may be used in closing the large wings, 

 which for want of strong nervures, probably require iheir as- 

 sistance. The dilated spine at the apex of the anterior tibiae, 

 and the beautiful pectinated basal joint at the tarsi, although 

 common in the Hymenoptera, are seldom more developed. I 

 have now little doubt that they are for the purpose of clean- 

 ing the antennae ; few insects are without a spine to the ante- 

 rior tibiae, and the basal joint of their tarsi is generally hol- 

 lowed out inside, if it be not always pectinated in this order. 



Three species only have been discovered ; Mr. Haliday 

 thinks the third may be a small variety of the second. 



1. G. fuscipennis Curtis Brit. Ent. }-)l. ^41. male. 



Smooth, black and shining, partially covered with yellowish 

 pubescence : antennae as long as the wings in the male, with 

 the fourth and following joints elongated: eyes castaneous: 

 ocelli pale : scutellum rugose : petiole with five very elevated 

 longitudinal lines: wings pale, fuscous, yellowish towards the 

 base, superior, with two white, and two or three brownish lon- 

 gitudinal lines on each ; a callous spot below the apex of the 

 subcostal nervure, and the curved one near the base, yellow- 

 ish brown : base of thighs, tibiae, and tarsi castaneous, the 

 hinder tibiae with a dark spot below the middle and the tips 

 of the tarsi black. 



The male figured I took in Norfolk many years since, and 

 Mr. F. Walker finds it amongst grass in woods near South- 

 gate, in June and July. 



2. G. cornutus Panz. 83. W. female. 



Antennae shorter than the wings in the male, having the 

 fourth and following joints subovate, excepting the apical one 

 (f. 1.): wings very pale, yellowish-luscous: petiole with five 

 faint elevated lines : base and tips of the thighs castaneous, all 

 the tibiae blackish in the middle, the hinder pair and the tarsi 

 castaneous only at the base. 



Males taken in February and April, in shady places ; and 

 females beginning of July, on the sea-shore at Holywood, by 

 Mr. Haliday. 



3. G. claviger Hal. MSS. Curtis's Guide, No. 3. 



Length three quarters of a line and one and a quarter. Male 

 undiscovered : females very similar to the last, with which they 

 were taken by Mr. Haliday. 



The plant is Pinguicula lusitanica (Pale Butterwort), from 

 Boscomb Chine, Hants, communicated by the Honourable 

 C. A. Harris.
