P. Hamadryas, Stal. {ys^w fiavitar sis, Chp.). 



This is perhaps the most variable species in the genus Faropsis, 

 its variation being so gi^eat that it is no easy matter to find two 

 similar specimens, and in many examples the two elytra are 

 dissimilar infer se. Presuming that I am not confusing more 

 than one species under the name (which I am fairly confident is 

 the case), P. Hamadryas is easily recognisable, for the structure 

 of its head refers it unmistakably to the small aggregate that I 

 have called "subgroup vi.," and it is the only species known to 

 me of that aggregate in which the antennfe can rightly be called 

 even moderately elongate and slender. These organs are much 

 like those of P. suhfasciata, Chp.; directed backward they extend 

 considerably beyond the base of the prothorax; all the joints, 

 especially the apical 5, are notably longer than wide; and there 

 is very little compression or dilatation of the apical portion — such 

 as there is commencing somewhat doubtfully at the 6th or 7th 

 joint and the 6th and 7th joints being scarcely appreciably 

 narrower than any of those that follow them. The head is much 

 flattened, and is closely and rather strongly punctulate (less 

 closely in rare examples) and longitudinally rugate in front. The 

 prothorax is finely and not closely punctulate except at the sides 

 where it is coarsely rugulose; its length is somewhat less than 

 half its width, and it is not much narrowed in front, with sides 

 feebly rounded, front angles somewhat acute, and hind angles 

 (viewed from above) well defined Vjut obtuse. The elytra are 

 non-striate except near the apex where feeble striae are visible; 

 their 10 series of punctures are close-set and not particulai'ly fine, 

 but are rendered somewhat inconspicuous by the presence on the 

 interstices of numerous punctures (mingled among smaller punc- 

 tures) not much smaller than those of the series. Some examples 

 are entirely testaceous in colour. The head usually bears a bifid 

 black patch which varies in size up to the extent of invading the 

 whole surface except the labrum. The pi'othorax varies (so far 

 as I have observed) only by the usual presence of a more or less 

 developed black spot at the middle of the base. The scutellum
