140 THE CANADIAN ENTOMOLOGIST 



Lec. by Henshaw, but Fall, in a recent letter, states that the sexual 

 characters are different arud that it is probably distinct. 



Exochomus marginipennis childreni Muls. — This variety 

 is common on oak throughout the winter, and mention is made of 

 it here only to record the taking of two specimens having the elytra 

 wholly pale, the usual subapical black spots being absent. 



Hyperaspidius militaris Lec. — Schwarz records this species 

 as "rare on oak shrubs." About Dunedin it is swept in numbers 

 in late autumn and early spring from a species of Helenium and 

 other low Composita% and has never been taken from oak. 



Scymnus oculatus, sp. nov. — Oval, convex. Head, thorax, 

 legs and last ventral wholly pale yellow; under surface reddish 

 yellow, finely and densely punctate; elytra black with a large oval, 

 common reddish spot on median third. Upper surface rather 

 thickly clothed with very fine semi-prostrate whitish hairs. Thorax 

 almost smooth ; elytra coarsely not closely punctate. Length 1 mm. 



Described from a single specimen beaten from Myrica cerifera 

 L. on March 24. A small and uniquely coloured species belonging 

 to Horn's Group B, i. e., having the metacoxal line running 

 parallel to the first ventral suture. Neither Horn nor Casey de- 

 scribe a form having a single common elytral pale spot, hence I 

 have little hesitation in adding a new member to this already 

 over-crowded genus. 



Tritoma dissimilis, sp. nov. — Elongate-oval, feebly convex. 

 Black, legs, antenna? and palpi reddish brown. Head and thorax 

 sometimes piceous, minutely alutaceous, finely and sparsely 

 punctate; sides of thorax straight from base to apex. Elytra 

 slightly wider at base than thorax, widest and most convex at 

 basal third, thence tapering to the rounded apex; striae with feebly 

 impressed rows of small, close-set punctures;- intervals very minute- 

 ly and sparsely punctate. Under surface finely and sparsely punc- 

 tate. Length 4-4.5 mm. 



Taken from beneath bark of dead oak; March 23, 24. Close 

 to T. angidata Say but larger, with distinctly longer and more 

 tapering elytra and straighter sides of thorax. 



Tomarus hirtellus Schwarz. Frequent beneath piles of 

 chips and old leaves. Not listed by Henshaw though it was de- 

 scribed in 1878.
