may prove to be a constant character when more abundant material 

 is examined". 



According to Emery, "the ^ of custodiens attains a larger size, and 

 in the maxima and media the middle joints of the flagellum are 

 clearly more than twice as long as wide. In fallax. they are barely 

 more than twice as long as wide, even in the largest 3 5; in the 

 smallest, the 3rd joint of the flagellum is barely half as long again 

 as wide, whereas in the smallest custodiens they are almost twice as 

 long as wide". 



I have some examples of the ^ minima of this race before me, 

 so determined by Dr. Forel. Apart from the colour, which is a pale 

 straw-yellow, a more abundant and more exserted pilosity here and 

 there, it does not . appear to me to be more than a very slight 

 variety. The 5th and 6th joints of the flagellum are twice as long 

 as wide, and the 4th joint a little more than twice.

 The examples from Grahainstown and Matroosberg are of the same 

 colour as custodiens. (S.A.M., R.M., G.A. colls.).

§. 2*7-7 mm. — ^ maxima. Not unlike a smaller, darker and 

 more compact custodiens, but without any silky pubescence or pattern 

 on the abdomen. Dark rusty-reddish brown, the tarsi and antennae 

 ferruginous, the thorax darker than the head; abdomen dark brown, 

 the apical margins of the segments pale flavous, (in ForePs original 

 description the colour is stated to be yellow-red, the abdomen brown : 

 this probably refers to a callow specimen). Pubescence short, decum- 

 bent, yellowish and not dense, almost absent from the head, more 

 abundant on the abdomen, but not sufficiently so as to mask the 

 colour or sculpture. The pubescence on the tibiae, tarsi and antennae 

 is oblique, very scanty on the femora. Abdomen with an abundant, 

 short, yellow and exserted pilosity. Thorax superficially rugulo>:e, 

 the sculpture strongest on the dorsum of the epinotum; abdomen 

 smooth, microscopically actculate. Pronotum more shining than the 

 rest of the thorax. Head very densely punctate-rugulose and also 

 somewhat reticulate, a small median longitudinal area on the clypeus 

 shining, with the sculpture more or less effaced. Mandibles with 

 7 teeth, the apical tooth long and acute ; smooth and shining over
