spines, besides spinules, the cephalic horns more foliaceous 

 and more sharply spined, with only one pair of spines in front 

 of them instead of two, and that simple ; male with eight 

 only, one of the lateral pairs not being developed. Post- 

 antennary spines reduced to minute tubercles. Vestiges of 

 wings and tegmina larger, those of the latter overlapping one 

 another and those of the former so as to conceal from view 

 all but about one square millimetre of the unarmed meta- 

 notum. The tergum of the first abdominal somite with but 

 one row of spines at its hinder end ; that of the terminal 

 somite of the female divided at its posterior margin into four 

 spinous processes. 



Colour. Body brown like rotten leaves, with the legs, 

 antennas, organs of flight (which have their principal nervures 

 darker), and spines lighter. 



J. Length of body 64 millims., head 4*5, pronotum 4*5, 

 mesonotum 14, metanotum 6, abdomen 27*25+ 8*5 = 3575, 

 tegmina 3*75, wings 7"3,fore femur 17, tibia 17, intermediate 

 femur 12'5, tibia 13'5, posterior femur 17"5, tibia 19*5, 

 antennae 47. 



? . Length of body 80 millims., head 7, pronotum 6'5, 

 mesonotum 16 - 5, metanotum 8, abdomen 31 + 12 = 43, teg- 

 mina 6, wings 11, fore femur 16'6, tibia 17, intermediate 

 femur 12"5, tibia 13*6, posterior femur 18, tibia 21, antennae 

 43-5. 



The fore legs and all the tibia? in the male of this species 

 are nearly quite simple. 



Hub. One male and two females from Fianarantsoa. 



XLIV. — Monobia confluens, a new Moneron, 

 By Aime Schneider*, 



[Plate XVIII.] 



I NOW present the description of a new Moneron, which ap- 

 pears to me to possess some interest. The name I give it is 

 in allusion to the community of life which is set up between 

 the different individuals of the same group, the different mem- 

 bers of a colony, as will be seen by-and-by. 



Monobia confluens lives in fresh water, and perhaps also in 

 moist earth. I met with it for the first time in June 1878. 

 I have had living representatives of it for about a week in a
