OTIORHYNCHIDAE. 623 



4194. Exonastus amplus sp. no v. 



Robust, moderately convex, without superficial inequalities, opaque ; 

 apparently rufo-fuscous, antennae and tarsi fusco-rufous ; thickly and 

 almost uniformly covered with depressed, obscure tawny squamae, and 

 rather paler erect setae. 



Rostrum a fourth shorter than throax, with a slender indistinct carina 

 along the middle, closely, rugosely, and longitudinally punctured in front, 

 and bearing very slender apical pale setae. Eyes slightly prominent, not 

 at all elongate, fully twice as distant from each other than they are from 

 the thoracic apex. Thorax nearly a third broader than long, slightl)' 

 rounded and broader at or behind the middle than elsewhere, rather 

 narrower in front than behind ; with a shallow impression along its frontal 

 half, and many bare punctures visible amongst the squamae, some of these 

 punctures near the sides, when looked at in different lights, appear trans- 

 formed into minute dark tubercles. Elytra large, nearly double the width 

 of thorax at the base, thrice its length, distinctly narrowed and curvedly 

 deflexed behind, with slightly divaricate apices ; they are rather finely 

 punctate-striate, with nearly plane interstices, being only slightly convex 

 along the posterior declivity. 



Tibiae briefly mucronate, the posterior pair more distinctly denticulate 

 than the others along the inner face. 



Scape straight, very gradually incrassate, just reaching the thoracic 

 apex ; basal two joints of funiculus equally elongate ; 3-7 obconical, third 

 slightly longer ; club elongate-oval, triarticulate. 



Underside densely covered with greyish scales and slender setae. Basal 

 ventral segment subtruncate between the widely separated coxae, medially 

 incurved behind, longer than the next, third and fourth together rather 

 shorter than second or fifth. Mentum subovate ; palpi invisible. Supple- 

 mentary mandibles well developed. 



Length (rostrum inclusive), 11 mm. ; breadth, 4| mm. 



Martinborough, near Wellington. One female, sent by Mr. A. C. O'Connor ; 

 31st October, 1916. 



4195. Exonastus fumidus sp. nov. 



Rufo-piceous, legs and tarsi fusco-rufous ; almost covered with dull 

 smoky brown scales, there being only a few scattered tawny-grey ones on 

 the elytra, similarly pale ones encircle the eyes, cover the scutellum, form 

 a patch on the hind angles of the thorax and a short fringe across its base ; 

 many of the setae are dark fuscous, others greyish. 



The rostral carina though slender is definite, the frontal sculpture is 

 less longitudinal and not at all strigose. The humeral angles are more 

 rounded and not quite as broad, the third and fifth interstices are slightly 

 but obtusely elevated, and there is a minute greyish scale i each of the 

 serial punctures of the elytra. The tarsi are more slender. The form 

 and peculiar sculpture of the thorax are, however, precisely similar to 

 those of E. ampins, so that E. fumidus may prove to be only a variety 

 thereof. 



$. Length (rostrum inclusive), 10 mm.; breadth, 4^ mm. 



Martinborough. Mr. O'Connor also forwarded another, mounted on 

 cardboard, measuring 8 X 3J mm. : this probably is the male.
