Ant(Mina^ ])ale yellow, of tlie ordinary Siiniiis strnetnro, 

 .about as long- as head and thorax, slender; 3rd joint niueh 

 longer than 2nd, 4 — 10 each shorter than its predecessor, 

 8 — 10 each slightly less slender than its predecessor, 10th 

 longer than broad, lltli rather stouter and a good deal 

 longer than 10th. Labruin very large, the middle part 

 niueli ])roduced, and the most ])rojeeting part trnneate, 

 -without notch or teeth. ]\landib]es moderately long, much 

 curved ; the left with two, the right with three teeth in the 

 middle. Head shining chestnut in colour, of the usual 

 Sunius form, but more gradually narroAved behind towards 

 the slender neck ; it is only sparingly and indistinctly 

 punctured. Thorax narrower than the elytra, of a sin- 

 gular, somewhat flask-shai)ed, form ; the sides of the hinder 

 portion rounded, then abru})tly narrowed in front of the 

 middle to make a slender neck ; the middle part is more 

 elevated than the sides, so that there is the appearance of 

 a longitudinal dej)ression on each side ; it is of a brownish 

 or chestnut colour and is ratlier coarsely punctured ; it has 

 a narrow impunctate line along the middle, and the lateral 

 portions are only indistinctly punctured. Elytra about as 

 long as thorax, rather shining, of a chestnut colour, each 

 with a darker oblique mark across the middle, and the 

 outer angle a little paler ; they are rather deeply, somewhat 

 coarsely and closely punctm-ed. Hind body broad, chest- 

 nut-yellow, a little shining ; the front portion of the two or 

 three basal segments rather distinctly punctured, the rest 

 scarcely visibly punctured. Legs very pale yellow ; the 

 first joint of the hind tarsus about as long as the other four 

 together. 



A single female of this extremely remarkable species 

 was captured by Dr. Trail on the 5th November, 1874 ; 

 but he has not transmitted to me the exact locality.
