2i'2. COLEOl'TERA. 



Uakaia Gorge, near Met liven. Described from a single individual 

 found by Mr. T. Hall on the 18th May. 1912. 



3599. Echinopeplus dorsalis sp. nov. 



The description of E. vervucatus, with the following exceptions, is 

 applicable to this species. 



Squamosity inoi'e infuscate, rosti'uni and thorax rather longer, elyti-a 

 shorter, legs and tarsi notably thicker. 



Thorax subcylindric, hardly any broader in front than it is behind, 

 its sides nearly straight, the surface witli tubercular and closer sculpture, 

 and witli a well-marked channel along the middle. Elytra almost 

 parallel-sided from the base to the jDOsterior elevations, -ird and 5th 

 interstices elevated from the base towards the middle, these \\hen 

 examined sideways are seen to consist of series of rounded tubercles; the 

 dorsum terminates as a pair of widely separated subrotundate elevations 

 which do not project backwards, the outer nodosity, on each elytron, 

 extends outwardly, and between it and the subsutural one there is a deep 

 but not wide sinuosity. 



Underside shining, piceous, covered with white scales and elongate 

 decumbent setae; terminal ventral segment with many minute as well 

 as coarser jjunctures. Prosternum incurved in front. The mentum 

 fills the buccal cavity, and the lunate basal impression has its front 

 margin slightly raised. 



Dr. Sharp's species of Ilettrodiscus, 2121 and 2590, have -i distinct 

 grooves on the rostrum, and the form of the elytral dilatations is 

 materially different. His genus Heterodiscus is synonymous with. 

 E chino pe2Jlus . 



Length (rostrum inclusive), 8J mm. ; breadth (nnxximum), 3| nun. 



Uakaia Gorge. Mv specimen was discovered on th'e 26th June, 1912, 

 by Mr. T. Hall. 



3600. Inophloeus pensus sp. nov. hio^Moeus \*i\^QOi\M.An. N.Z. C'()h'()])t., 



p. i39. 



Oblong, rather broad, slightly convex, oj^aque; nigrescent, antennae 

 and tarsi piceo-rufous; covered with depressed, rather small, dark, 

 and obscure tawny scales, those on the rostrum and sides of the thorax 

 of a more or less pinkish hue; the setae are slender, decumbent, and 

 gi'eyish, but are more conspicuous and erect on the posterior declivity. 



.Rostrum a third shorter than the thorax, slightly dilated in front,. 

 with a distinct but slender carina along the middle, broadly impressed 

 alongside it, the lateral carinae obtuse. Head short, with a narrow and 

 rather small interocular fovea. Thorax a little wider and rounded before 

 the middle than behind, slightly broader than long, without inequalities, 

 and with only a few fine punctui'cs visible. Scutellum subtriangular, 

 small. Elytra thrice the length of the thorax, rather broader than it 

 is at tlie base, with curvedly narrowed shoulders, their sides nearly 

 straight as far as the hind thighs, considerably narroAved behind, with 

 strongly produced apices; the disc slightly convex, rather finely and not 

 closely seriate-punctate; the 3rd and 5th interstices are as broad as the 

 others, only feebly elevated near the base, ratlici' more distinctly behind 

 and, though ending abruptly at the sunniiit of the (k'clivity, luit i:)ro- 

 minent and nodiform there, the suturi' is thick and horizontal but hardly 

 projects beyond the vei-tical declivity.
