INSECTA. 293 



B. Two oval clusters of numerous eyes (50 and more), trans- 

 verse, situated in front of the antennae at tlie sides of the head. 



Sub-genus Sphcerojwus BRANDT. Joints of antennae six, the last 

 large, truncated at the point. 



Sp. Sphceropceus insignis BRANDT, Zephronia ovalis GRAY ; a large species 

 from Java, figured in this Manual. 



Sub-genus Sphcerotherium BRANDT. Joints of antennae seven, the 

 sixth oblong, the seventh the least. 



Most of the species of this sub-division are from the Cape of Good Hope. 

 The genera Sphceropceus and Sphcerotherium are exotic, and seem to repre- 

 sent Glomeris in warm regions. 



Family II. Scolopendridce. (Chilopoda LATR.) Second pair 

 f feet cheliform, terminated by a strong hook, which is perforate, 

 overing the first pair of feet and the organs of manducation 

 )eneath, joined at the base, dilated, as if forming a second labium. 

 3ody depressed, covered above and below with horny scutes, the 

 ides membraneous. Feet lateral, mostly a single pair in each 

 egment, the last longest, extended backwards. Antennae usually 

 nore slender towards the extremity, with numerous joints (14 40 

 nd more). Organs of copulation situated at the posterior extremity 

 f the body. 



These animals live on animal food, insects, &c. Their nippers 

 (feet of the second pair) contain the excretory duct of a poison- 

 gland, which secretes a fluid deadly to small animals, as DE GEER 1 

 and LATREILLE 2 observed in flies ; the bite of the large native 

 species may cause great pain in man and violent inflammation and 

 swelling 3 .

 long as the body.
