SCTDMAENIDAE. 313 



Maxillary palpi with the 2nd joint elongate and thickened at the ex- 

 tremity, 3rd broadly oval, with a short slender basal stalk, the 4th short 

 and moderately thick. 



This stands alone. It differs from P. setosa in almost all its details, the 

 femora are not clavate, the basal joint of the antennae is much shorter, the 

 thorax appears to be gradually narrowed towards the front, and the pen- 

 ultimate joint of the maxillary palpi is essentially different.

Erua, near Waimarino. One male found amongst decaying forest 

 leaves, at an elevation of 2,400 ft., in January, 1910. Also a single female 

 with simple intermediate tibiae and less broadly oval 3rd joints of maxilliary 

 palpi. 



3737. Phagonophana sinuata sp. nov. 



Nitid, elongate, moderately robust and convex ; castaneo-rufous, legs 

 and antennae paler, tarsi and palpi fulvescent ; clothed with elongate, 

 principally erect, yellow hairs. 



Head not quite as broad as thorax, very gently narrowed behind the 

 small, somewhat convex eyes, its hind angles rounded. Thorax a little 

 longer than broad, widest and rather strongly rounded before the middle, 

 deeply and widely sinuate behind ; the median basal pair of foveae well 

 marked and suboblong but not large, the lateral deep and subrotundate. 

 Elytra oviform, twnce the length and at the middle double the width of the 

 thorax, a good deal narrowed towards the base, with a short basal impres- 

 sion on each. Pygidium scarcely visible. 



Legs elongate, femora gradually incrassate, tibiae finely setose. 



Antennae rather longer than head and thorax, moderately thick, dis- 

 tinctly pubescent ; 2nd joint somewhat longer than 1st, joints 3-6 

 elongate-subovate and nearly equal, 7th and 8th rather larger, 9th and 

 10th subquadrate, a little broader than 8th ; terminal conical, obviously 

 longer than 10th. 



Mesosternal process not prolonged to anterior coxae. Metasternum 

 much larger than abdomen. Posterior coxae subcontiguous. 



P. sanguineus, 1905, an Auckland species, has a manifestly larger head 

 and larger but less convex eyes, the thorax is somewhat longer but not so 

 strongly rounded or dilated before the middle, and the elytra are more 

 oblong-oval — i.e., much less curvedly narrowed towards the base. 



Penultimate joint of maxillary palpi gradually narrowed towards the 

 base, 4th small. 



Length, 2 mm. ; breadth, | mm. 



Hump Ridge, Southland. A solitary individual found by Mr. A. Philpott. 



Ohs. — The contiguity of the posterior coxae in many cases, particularly 

 when single specimens only are available, is very difficult to determine with 

 accuracy. The coxae are often pubescent, and in their natural condition 

 frequently smeared with sappy matter, in each case they appear contiguous, 

 but in many instances when thoroughly cleared of pubescence and extraneous 

 substances with the point of a needle and brushed with benzene, they are 

 found to be more or less distinctly separated. The maxillary palpi vary 

 considerably in structure, the penultimate and terminal joints especiallv. 

 The head and thorax differ greatly in form. The pygidium is usually covered 

 by the elytra, but in my genus Adrastia, which has widely separated posterior 

 coxae, and in several New Zealand species referred to Sc^dmaenus, it is often 

 fully exposed.
