PACHYTERrA BICOLOR. 181 



rior femora (about '/lo^^)- ^^^ anterior and intermediate 

 tibiae , all the tarsi , the 6 first joints and the base of 

 the 7^11 joint of the antennae are of a pale ochreous yel- 

 low. The posterior tibiae are black with only a slight 

 tinge of brown in the middle. 



The underside of the body (except the prosternum in 

 front and sides) is a bright steely blue with violet tinges. 



The punctuation of the head agrees with the description 

 of your insect but the underside below the mouth is coar- 

 sely punctured and almost corrugated. The longitudinal 

 groove on the forehead is deep with raised margins, and 

 extends from the back of the frontal tuber to the clypeus 

 where it ends in a transverse depression 1 millimetre dis- 

 tant from the anterior margin. There is a small smooth 

 space beyond the posterior end of the groove. 



The antennae have the first joint rather coarsely punc- 

 tured, the 2"d and S^d joints very slightly and all the 

 others not at all punctured. Their length reaches to ^j^^^^ 

 of the elytra. 



Thorax. The black erect short hairs form two velvety 

 patches occupying a great part of the upper surface, they 

 are slightly divided by a smooth line somewhat enlarged 

 at the two extremities, the anterior extremity being con- 

 cave and the posterior ending in a convex smooth patch. 

 The sides (in front of the lateral spines) and the under 

 surface is pulvinate, finely, evenly and densely punctate 

 (concinne confertissime punctata) forming a dull lustreless 

 surface, no oblique wrinkles are visible. 



The scutellum is long and triangular (Parry's figure is 

 correct) and it is velvety like the patches of the thorax, 

 it is quite flat (not raised at the sides) and no impressed 

 medial line. 



The elytra are broadly rounded and somewhat flattened 

 at the extremity and obliquely truncate at the sutural 

 angle. The whole surface is flnely and evenly punctured 

 and so closely as to make it appear coriaceous; very 

 slightly pubescent.
