584 COLBOPTERA. 



Scape evidently tiexuous, attaining the thoracic ajjex ; second joint of 

 funiculus distinctly longer than the basal, joints 3-5 longer than broad ; 

 club elongate-oval, rather narrow, quadriarticulate. 



Male. — Slightly darker. Rostrum dull, dark rufous, densely and minutely 

 sculptured, finely punctate, moderately stout in front, gently narrowed 

 behind ; scape medially inserted. In E. constrictus the rostrum is manifestly 

 more contracted behind the antennal insertion, the thoracic constriction is 

 larger and deeper, so that the oviform basal portion is shorter and more 

 rounded. One found at Belgrove. 



The female most nearly resembles the type of E. discalis (3141), also a 

 female ; the latter, however, is more opaque, its thorax is flat instead of 

 being depressed along the middle, and the antennae differ.

Howard Goldfield, near Glenhope. A single female, captured by Mr. T. 

 Hall ; 10th May, 1915. 



4141. Eucossonus nasalis sp. no v. 



Subdepressed, elongate ; rostrum and thorax dark fusco-rufous, antennae 

 and tarsi paler ; elytra a little shining, light chestnut-red ; irregularly 

 clothed with distinct, mostly decumbent, bright-yellow setae. 



Rostrum o])aque, with dense minute sculpture and fine punctures, a 

 third shorter than thorax, a good deal, yet gradually, narrowed behind 

 the middle ; its frontal half rather broad and parallel, nearly plane above, 

 with a feeble interantennal impression. Occiput large, nearly smooth. 

 Eyes widely separated, slightly convex. Thorax fully a third longer than 

 broad, rather deeply constricted near the apex, oviform behind ; flat and 

 nearly glabrous along the middle, minutely and densely sculptured, and 

 with numerous, rather distant, well-marked punctures. Scutellum sub- 

 rotundate. Elytra almost twice the length of thorax, slightly arcunte-emar- 

 ginate and rather broader than thorax at the base, their sides straight as 

 far as the curvedly narrowed posterior declivity ; finely striate-punctate, 

 interstices rugose, the third, and the suture, slightly elevated. 



Scape medially inserted, flexuous, moderately stout ; second joint of 

 the funicle evidently longer than the basal, third and fourth rather longer 

 than fifth ; club elongate-oval. 



The male of E. gracilis (2420) has the scape shorter, thicker, and nearly 

 straight ; the rostrum narrower and more parallel, the occiput less convex, 

 and the sides of the thorax less rounded. 



A careful examination of the anterior half of the rostrum will show 

 how it is differentiated from other recorded species, in these, ordinarily, it 

 is somewhat convex.

Wyndham, Southland. Mr. J. H. Lewis sent me a specimen of this 

 species along; with a varietal form of E. elegans (2419) on the 19th October, 

 1914. 



4142. Eucossonus disparilis sp. nov. 



Depressed, subopaque ; infuscate red, antennae and tarsi of a lighter 

 hue ; thinly clad with yellow, decumbent, slender setae. 



Rostrum a third shorter than thorax, its frontal half moderately broad, 

 ])arall"l, finely j)unctate and slightly nitid ; the basal opaque, with minut<' 

 dense sculpture, distinctly medially incurved. Occipitt rather short. Eyes
