who inhabit houses or dwellings where this class of insects abound. 

 In stables, horses if not removed, are driven almost frantic by them, 

 and cows and other large animals are attacked in the like manner, 

 but unless sickly are too strong to be overcome. Carrion of all kinds 

 is rapidly consumed, the find at once being covered by thousands of 

 insects, and in an incredibly short space of time the Avhole disappears, 

 and the ants again resume their march. Where plenty of food is to 

 be found the army takes a rest at intervals, and in doing this they 

 accumulate in a sheltered position under a stump, a stone, in a cellar 

 or similar place ; here they will rest for hours, and if Avet weather 

 intervenes, sometimes for days together. When assembled for rest 

 their appearance is much like a swarm of bees, their legs being 

 apparently adapted for the purpose. The cultivator welcomes the 

 approach of an army of these insects, as there is nothing more 

 destructive among his plants than the Blatidm or cockroaches, many 

 thousands of which are sought out and devoured by an army of 

 hunter ants. 



Since our last Bulletin the following have been kindly determined 

 for us by the British Museum authorities : — 



No. 15. — Siphonotus purpureas, Pocock. — Previously described 

 from St. Vincent. This is a small Myriapod or insect belonging to 

 the class to which are referred "centipedes" and "millipedes." It 

 is a very small but interesting insect. It was captured by Mr. Lunt 

 in the Gardens. 



No. 16. — Porphjraspts sp. — " Tortoise Beetle." — Larvse only ; 

 found upon a Bromeliacous plant. This is a very curious insect indeed, 

 the larvae looking like a small bunch of lichen and easily mistaken for it. 



No. 17. — Stichoplastis ravtdus, Simon. — This is a large spider 

 which lives on the ground under stones, damp wood, moss, or weeds. 

 It is somewhat like in form the one known as the Tarantula, but 

 neither as large or as hairy as that kind. 



No. 18. — Phalagium cosmetus pictus, Putz, is another spider of 

 the long-legged or " harvestman " section. 



No. 19. — Planarium sp. is one of the land leeches which are 

 fairly common in the Garden at times. 



No. 20.—" King Cockroach" " Electric Bug," Belostoma grande 

 Linn., or Nepa grandis, Linn.— This insect though resembling a 

 cockroach at first sight is seen on examination to differ in no little 

 degree, and it is placed by systematists under the family Nepidce, 

 Order Eemiptera, an Order which includes the plant bugs — Cicada, etc. 

 The insect according to a paragraph in the Port-of -Spain Gazette, a
