and deep at the base and slightly foveiform at its apparent 

 termination near the front, it is, however, prolonged to the 

 front margin as a slender stria, the broad curvate impression 

 near the front is most evident near the angles ; the disk is 

 slightly convex and shows traces only of transverse striae ; 

 the base is slightly medially emarginate : it is a fourth broader 

 than long. Scntellum striate at base. Elytra distinctly 

 broader than thorax at the base, humeral angles evidently 

 dentiform ; they are rather wider near the hind thighs than 

 elsewhere and considerably, obliquely, and sinuously narrowed 

 towards the extremity ; their striae are moderately broad and 

 deep and finely punctured ; the sutural two interstices are 

 rather narrow, the others broad and convex, the third has 

 three, the seventh five punctures. The eyes are prominent. 

 There are two setigerous punctures on each side of the middle 

 of the last ventral segment at the apex in both sexes. 



Underside shining piceous, head viridescent. 



Female. — Thorax slightly more rounded laterally ; hind 

 body broader, particularly near the apex ; thorax less cupreous 

 on the middle.

Horowhenua Lake. One pair from Mr. G. V. Hudson. 



Little difficulty will be experienced in separating this 

 species from T. cephalotes or T. hudsont, its nearest allies. 

 The nearly straight-sided thorax, posteriorly attenuated 

 elytra, and more slender legs are distinctive. 



Zeopcecilus optandus, sp. n. 



Suboblong, slightly convex, nitid, blackish green ; thorax 

 brilliant brassy and red, elytral margins rufescent; the legs 

 and basal joints of antennae piceous ; tarsi and palpi piceo- 

 rufous. 



Head convex, as broad as front of thorax, feebly irregu- 

 larly wrinkled; frontal impressions rather short; it is green. 

 Thorax one-fourth broader than long, its sides moderately 

 strongly rounded, but with a slight incurvature towards the 

 rectangular posterior angles ; discoidal groove and basal 

 fossae well marked ; there is a slight curvate impression near 

 the front, the base and apex bear distinct abbreviated longi- 

 tudinal striae, and there are numerous feeble undulating striae 

 across the disk. Scutellum feebly striate. Elytra oblong- 

 oval, rather gradually narrowed and only slightly sinuated 

 posteriorly, humeral angles dentiform ; their striae regular, 

 moderately deep, and finely punctured, the interstices mode-
