FIG. 13. Bruchus subarmatus, Gyll. ? 



Beetle, maggot, and chrysalis, all natural size and magnified ; injured 

 beans ; and fragment of case of chrysalis magnified. 



The above figures are taken from the specimens for- 

 warded by Mr. Bairstow from Port Elizabeth, including 

 the three stages of larva, pupa, and imago, together 

 with injured beans, which in some instances still con- 

 tained the pupa or imago. A description of the perfect 

 beetle is as follows : 



The upper surface is black, slightly shining, and with 

 fine depressed ashy brown pubescence. The head is very 

 finely punctured, with the eyes large and prominent, 

 and the forehead convex ; the antennae are black, with 

 the four basal joints dull red. The thorax is closely 

 punctured, a little rounded at the sides and obliquely 

 narrowed in front, the base is a little produced in the 

 middle over the scutellum, and has a slight central 

 impression and notch, the pubescence is closer and 

 forms a pale narrow longitudinal line in the centre. 

 The scutellum is nearly square, with a small central 

 notch behind. The elytra are very finely and closely 

 punctured with ten impressed rows of larger punctures 

 on each; there are three indistinct transverse marks
