In general appearance fairly close to plagiata, but with 

 apex of elytra pale and median markings reduced to a con- 

 .spicuously oblique fascia on each, the two combined forming 

 a wide reversed V . The markings are fairly constant, but 

 the general colour varies from a rather bright rusty-red to 

 dark (almost piceous) brown. The spine at the tip of 

 the fifth antennal joint is so short as to be almost 

 invisible. The four discal tubercles on the pronotum are 

 placed, as it were, at the corners of an exact square. The 

 elytral punctures are of three kinds — (1) moderately large 

 ones, dense at the base but becoming smaller and sparser pos- 

 teriorly; (2) some larger seriate ones, usually backed by small 

 granules; (3) very dense and small ones throughout. The 

 male differs from the female in having longer antennae and' 

 legs, with front tibiae moderately curved at the base and 

 wider at the apex, and the prothorax slightly longer. 



PORITHEA APICALIS, n. sp. 



Reddish-brown, appendages bright reddish-castaneous, 

 apical third of elytra flavous but partly infuscated. Moderately 

 clothed with very short pale pubescence, on the under-surface 

 somewhat sericeous in appearance; a few hairs on the elytra 

 and sides of prothorax and numerous ones on the appendages 

 and muzzle. 



Head with very dense, small, rugose punctures; clypeal 

 suture subfoveate on each side ; median line fairly well defined, 

 except posteriorly. Antennae thin, considerably passing 

 elytra, finely granulate-punctate ; spine at tip of third joint 

 rather short, on the fourth and fifth much shorter. Pro- 

 thorax considerably longer than wide, sides feebly rounded 

 in middle, with a very feeble median elevation, and four 

 feeble discal tubercles. Elytra not much but distinctly 

 wider than widest part of prothorax, sides feebly diminishing 

 in width to apex, where each is obtusely rounded ; with three 

 kinds of punctures. Femora clavate ; front tibiae lightly 

 -curved at the base. Length, 9h mm.

The prothorax is narrower than in plagiata, and the 

 elytral markings are very different. The apical two-thirds 

 of the flavous apical portion are somewhat infuscated, so that 

 in certain lights the elytra appear to have a narrow subapical, 

 very pale fascia, bounded posteriorly by a somewhat longer 

 and slightly darker one; the apical half of the femora is 

 somewhat darker than the rest of the legs, and the abdomen 

 is somewhat darker than the metasternum. The four pro- 

 Ihoracic tubercles are placed, as it were, at the corners of a
