402 COLKOPTERA. 



Ko.stiuni a third sliorter than tliorax, carinatc ah»ng tlio middle, tlie 

 apex finely punctate. Thorax as long as broad, slightly dilated near the 

 nuddle, the base bisinuate ; its central carina does not quite reach the 

 apex and becomes indistinct behind, at each side of it there is a shallow 

 impression, the sculpture concealed. Scutellum elongate, pale yellow. 

 Elytra oblong, a good deal narrowed behind, with slightly divergent but 

 not ))i'olonged apices, they are quite twice the length of thorax, rather 

 broader than it is at the base, which is bisinuate ; distinctly but not closely 

 seriate-punctate, each puncture has a narrow greyish scale within it : 3rd 

 interstices obtusely elevated at the base, plane along the middle, hori- 

 zontally nodiform on top of the declivity, which is broadly convex, but 

 not vertical, along the middle ; 5th interstices simple. 



Scape with elongate greyish scales and erect setae, gradually incrassate 

 and attaining the thoracic apex ; 2nd joint of funictilus rather shorter 

 than the basal, neither very elongate, joints 3-7 short and submoniliform ; 

 club elongate-oval, indistinctly quadriarticulate. 



This somewhat resembles 3118, but the squamae are almost wholly of a 

 reddish-coppery hue, the grey scales covering the sides of the elytra and 

 posterior declivity in that species being absent. The terminal nodosities 

 of the 3rd interstices are much less conspicuous and do not project beyond 

 the subcurvate declivity, which in 3118 is vertical, with prolonged apices, 

 and the 5th interstices are simple in this species. The joints of the 

 funiculus are evidently shorter. The space between the external cilia of 

 the posterior corbels is very narrow. 



The scrobes, as seen from above, are deep and widely open, and they 

 continue broad and smooth more than half-way to the eyes, and therefore 

 do not correspond exactly with the typical species of either Plityomida 

 or Tigones, and in Sharp's Protophormus they are described as being 

 " brevissimae." As those of 3118 are similar it must be placed with this 

 species. 



Length (rostrum inclusive), 8 mm. : breadth, 2| mm. 



Mount Alfred : 4th February, 1914. Unique. Found by Mr. T. Hall. 



Note. — As 1521 was described as Tigones caudata, 3118 must have its 

 name altered to Tigones asteliae. 



3866. Tigones thoracica sp. nov. 



Stout, unasperate, the derm slightly nitid, fusco-rufous, legs and tarsi 

 chestnut-red ; covered with depressed tawny squamae, those on the thoracic 

 disc of a light-coppery hue, bordered near the sides with some fuscous ones 

 which also form small spots on the declivity, on the summit of the last 

 there are some grey ones, these, however, do not form a definite fascia ; 

 the setae are erect, mostly pale. 



Ro.strum a third sliorter than thorax, carinate along the middle. Thorax 

 subcylindric, base and apex truncate, a little broader than long, slightly 

 narrowed in front, without distinct rugae ; an indistinctly raised space 

 extends from the base and tapers towards but does not reach the apex, 

 it is quite bare and closely rugose-punctate. Scutellum distinct, greyish. 

 Elytra subcordate, nearly double the width of the thorax in the middle, 

 tlu'ice its length, with slightly oblique shoulders, the apices slightly pro- 

 longed and dehiscent ; they are striate-puiictate, with nearly simple inter- 

 .stices, the 3rd, and the suture, being only a little raised near the base.
