fig, 2), which that author regarded as almost certainly the female of 

 Dorylus. 



Mr. Trimen also exhibited six cases fabricated by a South-African 

 Lepidopterous larva, of which the outer covering consisted, not of pieces of 

 grass, twigs, or other vegetable substances, but of particles of sand and 

 fragments of stone. The very peculiar aspect of these cases was due to the 

 fact that along each side was attached a series of much larger fragments of 

 stone, roughly triangular in shape, and regularly arranged in a single row, 

 with the longest point outwards ; the effect of this arrangement being to 

 give the case the general appearance of a Myriapod, and indeed a not very 

 remote resemblance to Peripatus. These cases (in two instances con- 

 taining the living larvae) were found in the dry elevated " Karroo " country 

 of the Cape Colony, in the districts of Beaufort and Clanwilliara, and 

 were presented to the South-African Museum by Mr. Thomas Bain and 

 Mr. J. K. Maquard respectively. Mr. Bain designated the larva as a 

 "geologist in miniature," but wrote that its local name among the Boers 

 (who regarded it as highly venomous !) was " Zand-Beestje." Mr. Trimen 

 was unable to rear the larva, owing to ignorance of its food-plant ; but, 

 from its appearance when out of its case, he thought that it would in all 

 probability liave furnished a large moth of the family FsychidcB.
