COLYDIIDAE. 175 



narrow elongate lidge extends backwards from the middle of the liase. 

 in line with that there is an oblong nodule near the liind tliigh, and on 

 the summit of the posterior declivity a prominent nodosity, a pair of 

 smaller ones outside the last extend towards the posterior femur, and 

 on the middle, but nearer the side, the)-e is a ridge similar to that near 

 the base. 



Antennae rather slender, as long as the thorax, their basal joint half- 

 hidden above; 3rd elongate, as long as the 2nd but much thinner; 4th 

 and 5th rather longer than broad; joints G-8 short and bead-like; 9th 

 larger than 8tli but smaller than the quadrate 10th; the terminal conical, 

 slightly narrower but rather longer than the 10th. 



Legs with more or less curvate setae, the tibiae a little arcuate and 

 thickened outAvardly near tlie middle; tarsi simple, their basal three 

 joints subequal and, together, shorter than the 4th. 



A peculiar and rather slender species, having a rather narrow 

 triarticulate antennal club. The thorax appears abruj^tly contracted 

 near the base, tlie flattened anterior lobe is entire and unusually large, 

 and its bispinose posterior angles aie without precedent. It should be 

 located near U . tiropterus, 3222, whicli, however, is a njuch larger insect 

 with strongly produced elytral apices. 



Length, 2| mm. ; breadth, nearly, 1 mm. 



Rakaia Gorge, near Methven. We are indebted to Mr. T. Hall for 

 the detection of this interesting species. One individual, found amongst 

 decaying leaves on the 5t]i June, 1912, is all 1 have seen.

p. 183 [Ahlabus). 



Oblong, moderately convex, variegate; fuscous, the front and ex- 

 planate sides of the thorax, the antennae and tarsi more or less castaneo- 

 rufous; unevenly clothed wath slender, rather short, somewhat curled or 

 suberect, yellow setae, which, on the elytra, are mingled with greyish 

 scale-like matter; on the middle of each elytron, beliind the jtosterior 

 feniui', there is a fuscous spot; legs and club dull rufo-fuscous. 



Head indistinctly granulate, only slightly elevated at the point of 

 the antennal insertion. Thorax rather bi-oader than long, its sides 

 ex])lanate and trilobed, the front lobe a little larger than the 2nd, the 

 3rd still smallei' and situated between the middle and base, posterior 

 angles obtuse and leaving a gap between each and the shoulder, the apex 

 deeply incui'ved near each side; disc uneven, indistinctly granulate, 

 trifoveate in front, the centi-al fovea narrower and not quite as large 

 and deep as the others; on the middle there is an ill-defined impression, 

 an<l the base is unequally trifoveate. Elytra as broad as the widest 

 pait of the thorax, fully twice its length, obliquely narrowed and sub- 

 vertical behind; tlieir sculpture is entirely hidden by the vestiture, but 

 appears to be seriate-punctate ; at the middle of the base, on each elytron, 

 there is a distinct nodiform elevation, and there is a pair of smaller 

 ones behind, besides these there are 2 or 3 which are more obtuse and 

 less easily seen. Legs rather sliort, tibiae straight, bearing curled setae. 



Antennae shorter than the thorax, very scantily pubescent; their 

 basal joint half covered by the lateral dilatation of the head, 2nd thick 

 and subobconical. 3vd as long as its predecessor but not half as stout, 

 the following two slightly longer than broad, joints 6-8 short and monili- 

 form, 9tli onlv sliglitly broader ; club al)iu]itly enlarged, densely pubes- 

 cent, bi articulate.
