OF NEW ZEALAND. 1485 



rounded, so that the middle is but little broader than the base ; 

 striate-puuctate, without distinct elevations; the broad pale space 

 densely covered with small scales, intermingled, and bordered, with 

 setae. Legs stout ; femora densely squamose above, the two hind 

 pairs deeply grooved underneath, the front pair deeply near the 

 apex only ; tibiae with distinct hooks, densely fringed externally, 

 with setae on the inside ; tarsi rather long, second joint longer than 

 broad, third moderately broad and deeply lobed. 



Underside blackish, moderately closely punctured, clothed with 

 rather coarse, oblong, yellow scales. The lower part of the side of 

 the thorax, just above the angle of the pectoral canal, slightly 

 curved outwardly and setose ; this may be called the ocular lobe. 

 The canal wider near, but not at, the front than elsewhere, its hind 

 border elevated between the middle coxae. Metasternmn short, on 

 nearly the same level from one side to the other. Basal ventral seg- 

 ment large, depressed, broad in front and extending forwards beyond 

 the coxae, second half the length of the first, with a distinct sinuous 

 frontal suture. 



This can only be confounded with A. scitus, which, however, is a 

 much prettier insect. These two species can be easily separated 

 after an examination of the undersides.

OBS. Acalles scitus. The two basal segments of the abdomen 

 are on an abruptly higher plane than the three last, on the second 

 the scales are slender, still more so, and quite small, on the 

 first. The hind border of the pectoral canal is acutely elevated and 

 sharply rounded in line with the back of the coxae. The flat basal 

 segment of the abdomen seems to extend right up to the border of 

 the canal, so that the metasternum seems to consist of an oblique 

 ridge from the hind coxae to the canal-border. The pectoral canal 

 is similar in A. dolosus, its front angles extend a little inwards, the 

 sides converge a little near the coxae, so that the cavity is a good 

 deal wider near the front than it is elsewhere. It will be apparent 

 that, though an abraded or imperfect A. scitus is, superficially, ex- 

 tremely like an A. dolosus, the sternal structure warrants their 

 generic separation. 



The perfect .4. scitus has coarse reddish-brown scales on the 

 thorax, an interrupted grey line along the middle, and grey scales 

 nearly form a line across it, the erect setae are blackish. The scales 

 on the elytra are very small and nearly ferruginous for the most 

 part ; the broad space on top of the declivity is composed of cream- 

 coloured squamae, with grey setae at each side, but in front and 

 behind it is bordered with angulated black spots ; there are four 

 small black crests between the middle and the base ; at each side of 

 the hind-body there are three lines of black-and-white scales ; the 

 elytral punctures are moderately coarse and distant, and do not 

 form striae.
