beautiful bands of golden green, or blue scales with which it is 

 adorned. The thorax is nearly covered with scales, the only denuded 

 parts being a band across the centre and a small space follow- 

 ing the posterior margin. On the elytra is a coloured band at the 

 base, and a second in the middle, and the apical third of the elytra 

 is covered with scales, with the exception of an oblong space on 

 each side between the suture and outer margin. The antennae are 

 pitchy, and sometimes reddish at the base ; the legs are also pitchy, 

 but the femora are red at the base ; sometimes the red extends almost 

 to the joint, and in some specimens the apical half of the femora is 

 dusky. The rostrum is rugose above, and has two irregular ridges 

 at the base ; these nearly meet near the transverse impression which 

 separates the head from the rostrum, but diverge in front ; on the 

 side of the rostrum is a deep longitudinal groove, which commences 

 at the anterior angle of the eye and runs into the groove for the an- 

 tenna. In the male the thorax is scarcely narrower than the elytra, 

 and the terminal segment of the abdomen is semicircular, coarsely 

 punctured, and has a fovea in the middle. In the female the elytra 

 are more ovate, decidedly broader than the thorax, and pointed at 

 the apex ; the terminal segment of the abdomen is conical, has a 

 few punctures and some irregular little grooves near, and running 

 for the most part parallel with, the margin. 



Apocyrtus acutipennis . 



Ap. niger, parum nitidus ; rostro rugoso, linea longitudinali ad basin im- 

 pressa; capite inter oculos squamis viridibus ornato ; thorace convexo, 

 lateribusrotundatis, tuberculis nitidis crebre obsito, fascia antica, lateribus, 

 maculisque duabus, squamis viridibus vestito ; elytris ovatis, tuberculis 

 minutis subacutis crebre obsito, fasciis duabus, maculisque tribus sub- 

 apicalibus viridibus. Long. corp. 4^ — 5 lin.

This species is very closely allied to the Ap, Chevrolatii, but is at 

 once distinguished by the black colour of its legs and antennas, by its 

 having a spot on the suture towards the apex of the elytra, the space 

 between the eyes is broader, &c. The rostrum is very rugose, has a 

 longitudinal depression in the middle and another on each side of 

 this : on the side in front of the eye is a longitudinal groove, which 

 posteriorly joins that which separates the rostrum from the head, and 

 anteriorly it partially runs into the antennal groove ; not so distinctly 

 joining that groove as in Ap. Chevrolatii. The thorax is globose in 

 the male and but little narrower than the elytra, which are slightly 

 dilated in the middle and somewhat rounded at the apex. In the 

 female the thorax is less globose, proportionately smaller, and the 

 elytra larger, more ovate, and at the apex they slightly diverge, 

 are curved downwards and acutely pointed : here the terminal seg- 

 ment of the abdomen is impunctate and remarkable for a deep and 

 largish fovea at the apex, a character which the female Ap. Chevrolatii 

 does not exhibit, neither has the corresponding sex of that species 

 the acute apex to the elytra. In the male of the present species the 

 terminal segment of the abdomen is semicircular and rugose. As re-
