166 Mr. W. L. Distant on TJ'/uJeserihcd Genera and 



lobes of tlie head coarsely punctate, central lolje more sjsaringly 

 jjunctate, a space before the ej^es and at base, levigate. Pronotum 

 coarsely but somewhat sparingly punctate, with a narrow central 

 levigate impression, posterior angles obtusely subprominent. Scu- 

 tellura with a small slightly-raised levigate callosity near each 

 basal angle ; basal area somewhat transversely rugulose. Membrane 

 gale greyish. 



Long. 12-13 milliin. Exp. pronot. aug. b\ millini. 



Habited. India, Naga Hills (Chennell — Coll. Dist.) ; 

 Burma, Tavoy (Coll. Dist.), Karen Hills (Doherty — 

 Coll. Dist.). Specimen without locality (Brit, Mus.). 



A species slightly aberrant from the usual form of the 

 genus, by its elongate body, the central lobe about 

 reaching the apex of tlie head, and the more slender 

 scutellum. In other respects it conforms to Ocliro- 

 'plietra, the type of which I have, by the courtesy of 

 Dr. Aurivillius, been able to examine. This species, 

 however, is of the most extraordinary variability, not 

 only as regards markings, which are not abnormal, but 

 exhibiting a plastic mobility in structure which is very 

 unusual. In a series collected for me by Mr. Doheity 

 on the Karen Hills there is a specimen in which the 

 anterior apices of the posterior pronotal angles are pro- 

 duced in acute spines directed forwardly and somewhat 

 upwardly. This might be taken to denote a distinct 

 species did not the series contain three specimens in 

 which this sjDine is developed on one siele of the ijronotum 

 only — left side in two specimens, and right side in the 

 third. 



In most of the Karen Hills' specimens the colour is 

 a little more pronounced than in those from the Naga 

 Hills and Tavoy ; in particular the dark punctuation on 

 the scutellum is accentuated, especially at base and on 

 each side a little before apex. 



Parodius, gen. nov. 



Head about as broad as long ; lateral margins distinctly sinuate, 

 lateral lobes a little longer than the central but not meeting in 

 front, broad, subfoliaceous, their margins upwardly recurved ; 

 antenna3 finely hirsute with the second joint a little longer or 

 subequal in length to the third, fourth joint longest, l)asal joint 

 almost reaching apex of head. Pronotum with the anterior angles 

 toothed, the lateral margins obliquely subtruncate, posterior angles
