266 Mr. F. Bates' Descriptions of 



base finely margined ; base bisinuately emarginate, a slight 

 impression at each side the middle gives the appearance of 

 a median basal lobe : scutellum strongly transverse ; elytra 

 oblong, convex, a little wider than the prothorax, sides 

 subparallel, rather strongly margined (especially at base 

 and apex), reflexed ; base emarginate ; humeral angles pro- 

 minent : epipleural fold entire behind : prosternal jirocess 

 curved round the coxns : mesosterrmm declivous : inter coxal 

 process narrow, triangular, apex narrowly rounded : legs 

 short ; femora rather robust, comj^ressed ; anterior tibicB 

 triangular, the outer margin very finely denticulate ; the 

 4 posterior sublinear, the outer apical angle of the inter- 

 mediate produced (not dentiform) : last joint of all the 

 tarsi elongate, the 1 st joint of the posterior longer than 

 the 2 following united. 



This genus is evidently related to Phtora ; it is distin- 

 guished from it by its much larger size, relatively broader 

 form, differently formed mentum,* large transverse scu- 

 tellum, base of prothorax bisinuately emarginate, and epi- 

 stoma produced beyond the level of the insertion of the 

 antennfe, not broadly rounded. 



A. riijipes, n. sp. 



Long, 2lin. ; oblong; nitid; piceous; legs, antennae, 

 j)alpi, labrum and anterior border of head rufous; head 

 and prothorax finely and evenly punctiu-ed ; elytra punc- 

 tate-striate, the strias very faint, obliterated at sides and at 

 apex ; intervals very finely and not closely punctured ; 

 underside pitchy, very finely reticulately rugulose and 

 punctured ; prosternum Avitli a fcAv scattered longish hairs. 



Ildh, — New Zealand. One example. 



This must be very near to the Phtora Lifuana of 

 Montrouzier, but his description, being so brief, is almost 

 worthless ; for comparison he describes it as of an uniform 

 ferruginous-brown colour ; if that be so, it is a different 

 species from ours.

* In the present genus the mentum appears, on a first view, to be trans- 

 versely quadrangular, but, on a closer examination under a high power, 

 the sides anteriorly and the apex are found to be strongly inflexed, so that 

 the form is really trapezoidal.
