3 2. Somewhat resembling P. nigritarsis in size and shape. Frons much narrower, being less than half the 
width of the rostrum, clayish pubescence of occiput and hinder part of frons restricted to two vittee 
bordering the eyes. Pronotum less convex than in P. nigritarsis, lateral carina extended beyond middle ; 
two dorsal luteous vitt, constricted in middle, and a short mesial basal vitta, connected with each other 
and with the pubescent grey sides along the carina, which is subbasal, standing nearer the basal edge 
than in P. nigritarsis. Elytra grey at basal edge, this pubescence extending backwards along suture to 
middle, the posterior half of the vitta dilated, this dilated portion produced straight laterad behind the 
feeble basal callosity towards a short vitta which is situated in the sixth interspace; from the hinder 
part of the sutural patch there runs on each elytron a thin oblique angular line backwards and 
sidewards, nearly reaching a small limbal postmedian spot; an apical patch on each elytron rounded 
towards sutural angle, subtruncate towards disc; a small double spot laterally before middle; these 
markings grey or luteous. Pygidium and under surface uniformly greyish-white, the former rounded 
at apex. Prosternum subvertical before coxa, this portion about one-third the width of the coxa. 
Mesosternal process truncate, with the angles rounded. Abdomen feebly flattened mesially in ¢, the 
last segment deeply impressed, short, rounded; last segment of 2 rufescent, longer than segments 2 to 4 
together, slightly sinuate. Legs rufescent, thinly pubescent white, apices of tibiz and the tarsi black, 
fore and mid tarsi more or less thinly pubescent white above ; first tarsal segment more than half the 
length of the tibia. 
Length 4-5 millim.

This and P. costatus are the commonest species of Phenithon. Variable in the amount of grey pubescence on 
the upperside, the elytra sometimes irrorated all over with grey (P. inconditus, Fihr.). Mid and hind 
tibis with a small but distinct apical spur in ¢. First segment of all tarsi white, except the tip. 
Anal sternite of ¢ not impressed, of 2 emarginate.
