180 Mr. G. Lewis on 



Oblong-oval, somewhat convex, elytra greenish blue, the 

 thorax with a violaceous tint ; the head feebly impressed 

 anteriorly, finely and evenly punctulate, lateral stria not well- 

 marked and ceasing behind the mandibles, transverse stria 

 absent ; the thorax somewhat arched at the sides, marginal 

 stria ceasing behind the eye, punctured at the sides, punctures 

 gradually becoming microscopic on the disk, scutellar fovea 

 very small; the elytra — humeral, subhumeral, and dorsal stria? 

 all complete, the fifth alone being evanescent just before the 

 base, stria? crenulate, interspaces evenly and microscopically 

 punctulate ; the propygidium with rather large shallow punc- 

 tures, sparsely set, and with two shallow posterior impressions ; 

 the pygidium, punctures much smaller, with a small fovea on 

 either side at the base ; the legs are obscurely red. 



In outline this species resembles P. Msteroides , Mars., 

 especially in the form of the thorax. 



Plab. Natal (Durban). Two examples, one in the South- 

 African Museum. 



Pachycrcerus puncticollis, sp. n. 



Oblongus, parallelus, convexus, virescens ; pronoto undique punc- 

 tata, stria marginali pone oculos interrupta ; elytris striis l a -4 m 

 integris, 5 a dimidiata, 6 a subintegra ; prosterno bistriato : meso- 

 sterno stria integra. 



L. 4| mill. 



Oblong, parallel at the sides, convex, elytra brassy green, 

 thorax faintly coppery ; the bead impressed anteriorly, 

 sparsely punctured at the base ; ocular stria continues along 

 the epistoma, with a transverse line (which marks the suture) 

 angulate in the middle, the angle pointing towards the mouth 

 (the reverse direction to that in P. Ritsemce, Sch.) ; the thorax 

 wholly and evenly punctured throughout, marginal stria 

 widely interrupted behind the neck; the elytra, stria? 1-4 

 complete, 5 dimidiate, apical, with a fovea at the base, sutural 

 only shortened before the scutellum, all the stria? slightly 

 crenulate ; the propygidium and pygidium are punctured like 

 the thorax. 



This species is similar in size and facies to P. cyantpennis, 

 Mars., but differs in the thorax being punctate before the 

 scutellum, the presternum being wider between the stria?, and 

 the mesosternal stria is complete anteriorly. 



Bab. Central Africa.
