1038 Mil. A. LOVUIMIXJIS: NOTKS ON 



89. SciiiSTOCKUA GUEGAiiiA Foi'sk. Loousts of tliis species 

 travelling in a S.S.W. direction have literally peppered tlie sky 

 to-day, but vagaries in the wind have caused many of them to 

 settle. (Morogoro, ll.xii. 16.) 



The most striking thing about the insect-life to-day were the 

 locusts of two species (the second being Zonocerus elegans) which 

 were simply swarming everywhere; the herbage was literally alive 

 with the stragglers of the swarm of yellow adults that passed 

 over here three days ago. I met a native woman putting them 

 into a pail for dinner. On the middens outside the huts are 

 great piles of wings and hind-legs, the relics of recent feasting. 

 (Morogoro, 14. xii. 16.) 



90. Zonocerus elegans Thunb. A rather surprising situation 

 for immature grasshoppers of gaudy colour were the holes caused 

 by the larvae of many species of longicorn in the thorn-trees, 

 whose timber was alinost as hard to cut as stone. Yet 1 took many 

 of these young grasshoppers as high up as seven feet, and might 

 have found them still higher had I chopped further up the stems. 

 Immediately their hiding places were laid open they sprang into 

 the air. (Mbunyi, 17. v. 16.) 



This species is very interesting on account of the small 

 proportion that develop wings. The insects frequently mate 

 while their wings are quite rudimentary. The development of 

 the wings is, I take it, a matter of no importance to the owner's 

 safety, which is guaranteed to a great extent by its gaudy, apose- 

 matic colouring and offensive smell. (Morogoro, 14. xii. 16.) 



These grasshoppers, apparently so warningly-coloured, are eaten 

 with avidity by hungry lizards (Gerrhosaurus major) and some- 

 what reluctantly by a Chameleon (C. clilepis dilepis)*'. (Morogoro, 

 22.x. 17.) 



This species comprised part of the stomach contents of a 

 Ci-ested Cuckoo {Ooccysies glandarius). (Morogoro, 29. i. 18.) 



Also found in the stomach of another species of Cuckoo {Goc- 

 cystesjacohinus). (Morogoro, 29. xi. 18.) 



91. Phymateus VIRIDIPES Stil. Captured three large P7i7y???«.^eMS 

 insects of the usual vivid green colour with scarlet, blue, and green 

 under-wings; there were four of them on the bush, nevertheless 

 I did not notice them till the first moved. A curious mixture of 

 protective and aposematic colouring, they are rather slow in their 

 movements and only take short flights, relying for safety on the 

 frothy bubbles discharged from glands situated just behind the 

 large jumping-legs. (Ngari Mtoni, near Anisha, 4.iv. 16.) 



Took a pair of these Acridians at Morogoro, where they are far 

 fi'om common. (Morogoro, 10. i.l7.) 



92. Cystoccelia absidata Karsch. Just by my tent someone 

 caught a ver-y queer orthopteron. Its length over all is 4| inches ;

 Ent. Soc. 1921, pp. 8, 33, 53, 98).
