34 PACHYTERIA PUNCTICOLLIS. 



The elytra gradually narrowing from the base , their apices 

 conjointly rounded ; the suture impressed from a little be- 

 fore the blue coloured apical half down to a little before 

 the apex; another although slight longitudinal impression 

 is present on each elytron between the sutural impression 

 and the lateral margin, and extends from a little before 

 the blue coloured apical half as far as the apical fourth of 

 the elytra. The luteous coloured basal half of the elytra 

 is covered with large and closely set punctures , which how- 

 ever become fine and dispersed towards the base and the 

 suture. The punctuation on the blue coloured apical half 

 and on the small impressed portions of the basal half is 

 very fine and extremely dense , except on the streak between 

 the sutural and lateral impression where the punctures are 

 larger and wider apart. The impressed regions are more- 

 over covered with a velvety pubescence, which has a black 

 color on the blue portion and a luteous color on the lu- 

 teous portion of the elytra. 



The under surface of the thorax partially covered with 

 a thin silvery pile ; the under surface of the abdomen naked 

 with the exception of a little transverse patch of a silvery 

 pubescence on the sides of the four basal segments. The 

 metasternum is provided on the middle with a longitudinal 

 impressed line and covered on the posterior half with some 

 large punctures ; the ventral segments of the abdomen are 

 densely covered with almost imperceptible punctures inter- 

 mixed with a few larger ones ; the 5th ventral segment 

 shows a broken pro-apical margin which is preceded by 

 a semilunar impression; the apical margin is slightly emar- 

 ginated. 



The legs are slender, especially the posterior pair, the 

 femora of which are almost linear , whereas the metatarsus 

 of the same pair is distinctly longer than the two following 

 joints taken together. The femora are strongly, the tibiae 

 very finely and densely punctured.
