238 THE CANADIAN ENTOMOLOGIST 



Ischyrus tripunctatus, sp. nov. 

 Form and size of the well-known /. 4-punctatus Oliv., from 

 which it differs in sculpture and colour as follows: Head much 

 more coarsely punctate and with a reddish-yellow spot each side 

 between the eyes; thorax less coarsely punctate than head, but 

 more so than in 4-punctatus and with three instead of four round, 

 black spots, the median one twice the size of the lateral ones, the 

 latter more distant from the margin than in Ji.-punctaHis . Elytra 

 more distinctly alutaceous and with fine, scattered punctures along 

 the intervals; the common scutellar black spot larger and more 

 evenly quadrate, separated by a narrow, yellow cross-bar from a 

 black space which extends three-fourths to apex and which is 

 partially broken by a yellow line extending backward to apical 

 third along the fifth interval; apex yellow, the oblong, black, sub- 

 apical spots of Jf-punctatiis lacking. Length 7 mm. 



Described from a single specimen t^ken near Dunedin, 

 February 8, from between the leaves of a large air plant, Tillandsia 

 utricidata L. 



Soronia brunnescens, sp. nov. 



Elongate-oval, feebly convex. Uniform pale reddish-brown, the 

 legs but slightly paler. Head finely and sparsely punctate, broadly 

 impressed between the eyes, which are prominent and coarsely 

 granulated; antennal grooves almost straight. Thorax two-thirds 

 wider than long, apex broadly and shallowly emarginate; sides 

 broadly and regularly curved, the hind angles obtuse; disc very 

 finely, sparsely and evenly punctate, the margins moderately ex- 

 planate and feebly recurved. Elytra slightly wider at base than 

 thorax at middle, their margins more widely explanate, sides 

 broadly curved from base to the rounded apex; disc glabrous, 

 without trace of costae, punctate like the thorax. Abdomen 

 minutely pubescent, finely and densely punctate. Length 3.5 

 mm. 



Described from three specimens taken at porch light at 

 Dunedin, June 10. From the other members of the genus, which 

 are easily known by the presence of a frontal lobe which projects 

 over the basal joints of the antennae, brunnescens is distinguished 

 by its uniform pale colour, smaller size and lack of elytral costse.
