 Pachyrrhynchus orbifer subsp. azureus Schultze, Philip. Journ. Sci. 



21 (1922) 577, pi. 2, fig. 8. 



Black ; head and prothorax shiny, elytra dull, very finely coria- 

 ceous. Very nearly related to P. moniliferus Germ. Rostrum 

 in apical half scatteredly punctate, basal half with a rather 

 strongly pronounced dorsal depression and a rather indistinct 

 longitudinal groove in the middle. Front with a somewhat 

 squarish bluish green scale spot, another oblong spot below each 

 eye. Prothorax hardly broader than long, subglobular, very 

 finely scatteredly punctate. In the middle an irregularly broader 

 or narrower scaly crossband which is confluent with a scaly 

 area at each side. From the discal part extending to hind 

 margin a wedge-shaped scale spot. The scaleless parts on pro- 

 thorax form three smaller or larger areas, one in the anterior 

 and two in the posterior half. Elytra punctate-striate, the 

 punctures more or less strongly pronounced. Elytra beset with 

 bluish green scales with the exception of a cross row of three 

 bare areas at base, the larger one of which is divided by suture ; 

 another cross row of three bare areas in apical half of elytra 

 and a small bare roundish area at apex. 



These bare or scaleless areas are very variable in size and 

 shape, and may be confluent laterally or longitudinally. In 

 most specimens the bare areas are surrounded by pale greenish 

 scale lines (Plate 6, figs. 2, 3, 4, 7, 8) which coloration contrasts 

 with the other scale coloration of the elytra. Femora with an
