gards the markings, which are formed of bluish green scales, they 

 consist of a narrow line on the front and sides of the thorax and two 

 spots, one on each side of the centre : on the elytra are two bands, 

 one at the base and the other in the middle, a spot on the suture 

 between this last band and the apex of the elytra, and a subapical 

 patch on each side, which sends out a branch to join the central 

 fascia at the outer margin of the elytron, which has an almost unin- 

 terrupted band of scales. In the female insect I have further to no- 

 tice that the elytra have a hump on the suture situated rather behind 

 the apical third. 



Apocyrtus concinnus. 

 Ap. niger, parum nitidiis ; rostro nigoso ; thorace subgloboso, crebre tubcr- 



culato, pone medium linea transversa, marginibus anticis laterahbusque 



auveo-viridibus ; elytris ovatis, cvebre tuberculatis, ad apicem fasciisque 



dnabus, aureo-vii"idibus. Long. covp. 4 bn. 



This species very closely resembles the Ap. acutipennis (like that, 

 differing from Ap. Chevro'latii in having black legs), but differs in 

 having the markings of a golden-green colour, a narrow band on the 

 thorax rather behind the middle, and the whole apex of the elytra 

 covered with scales; these, though somewhat scattered, do not arrange 

 themselves into spots as in acutipennis. In form and sculpturing there 

 are moreover some points of distinction. The rostrum is very rugose, 

 and does not exhibit any longitudinal channel ; the elytra in the 

 female are not produced into an acute angle at the apex as in acuti- 

 pennis, and the terminal segment of the abdomen in this sex is de- 

 stitute of the large fovea, and is rather coarsely punctured. The elytra 

 are more thickly tuberculated. The space between the eyes is con- 

 siderably broader and more distinctly punctured than in Ap. Chevro- 

 latii. 



Apocyrtus hispinosus. 

 Ap. niger, squamis viridibus adspersis ; thorace valde globoso,' tuberculis 



crebre obsito ; elytris rugosis, subseriatim tuberculatis, ad apicem bispi- 



nosis ; femoribus rufescentibus. Long. corp. 3^ lin. 



This species is less than the Ap. impius of Erichson, and has the 

 elytra more constricted at the base. The rostrum is thickly punc- 

 tured, and has a broadish but shallow longitudinal impression ; it is 

 separated from the head by a transverse groove, which runs on each 

 side into a large fovea situated immediately in front of the eye ; these 

 lateral pits contract the hinder part of the rostrum, which is some- 

 what humped and raised above the plane of the head. The head is 

 distinctly punctured between the eyes, where there is a longitudinal 

 groove ; the eyes are large and but little convex. The thorax is 

 truncated before and behind, but nearly of a spherical form ; above 

 it is thickly studded with glossy, rounded tubercles, and rather 

 sparingly sprinkled with bright green scales. The elytra are very 

 convex and of a short ovate form ; the apex of each elytron is pro- 

 duced into a spine, which is evident to the naked eye, and there is a 

 small hump at the suture at a short distance from the apex ; the 

 surface of the elytra is very rough, being broken up into ruga; and 

 tubercles — the latter form longitudinal striae. Bright green scales are
