suturaque ad basin albido-squamosis, elytris ad basin circa scuteUum

This species has the surface more densely clothed, and with a rather more 

 definite limitation of the marks than is usual in the allies. The antennse are pale 

 red, and the rostrum is red, the head behind the eyes more obscure ; both are 

 densely punctate, as is also the thorax, and all these parts are clothed with depressed, 

 fine, hair-like scales of a pale flavescent colour, a white line of rather coarser scales 

 running along the middle of the thorax ; this white line is continued along the 

 scuteUum and on the basal portion of the suture ; and around the pale line thus 

 formed at the base of the elytra, there is a patch of colour of a much darker red 

 than the general ground colour, and on the middle there is an irregular sub-angulate 

 fascia of similar dark vinous-red colour : the rest of the elytra have a pale clothing, 

 which is most dense and definite behind the medial fascia : the surface bears a few 

 fine, upright, pale hairs. 



Mr. Helms has sent five specimens of this species from Grey- 

 month ; and I have a pair in bad condition of a closely allied but 

 distinct species, found by Mr. Wakefield at Christchurch. 



Tychantjs bufo, n. sp. 



Latus et brevis, squamuUs depressis densissime vestitus, rostro fere 



nudo, lafo, opaco, nigro, antennis ferruqineis ; profhorace antice valde 



angustato, margine anteriore in medio bl-nnqulariter prominulo ; elytris 



utrinque p)rope scuteUum sub-nodosis, posferius declivis utrinque ante 



medium fascia albida, cuneiformi. 



Long, rostr. excl., 5^ mm. ; lat., 3 mm. 

 The rostrum is scarcely so long as tlie thorax, is not curved, but is broad, dull 

 above, punctate, but not densely, some of the punctures bearing a depressed seta. 

 The antennae are entirely feri'uginous. The thorax is as broad behind as the elytra ; 

 from the base to the middle it becomes slightly broader, and has sharply defined 

 sides, in front of this it is excessively narrowed, the elevations over the head are 

 very distinct, and there are on the middle two transverse, rather ill-defined, sub- 

 angular elevations, the wliole surface evenly clothed with rather coarse griseous- 

 brown scales, probably variable in colour. Elytra clothed with scales, finer than 

 those on the thorax, but rather similar in colour, and not variegate, except by a 

 large, pale, very conspicuous, wedge-shaped mark on each, extending from each side 

 towards the suture, which, however, it does not reach ; on the basal portion there 

 are some coarse pits. The legs are densely squamose, and the femora have a large 

 angular prominence. 



This insect has more the facies of a Si/mpedius than a Tgchanus ; 

 indeed, the limits of these Acalles genera are not at present very 

 definite. 



Mr. Helms has sent T. bufo as No. 134, and informs me it is rare 

 at Greymouth.
