(5.) Em'pusa gougyloides (Fabr.). — This Mantis was re- 

 cently received, along with many other Orthoptera, from 

 India. Ceylon is the habitat usually assigned to it. The 

 peculiarities of its form, compared with that of Mantis 

 religiosa, were pointed out, and specimens of Blei^haris 

 mendica, Harpax ocellaria, and Mantis hicornis, were associ- 

 ated with it to show the gradual differentiations of the 

 flattened projections on the body and limbs of these forms. 



(6.) Tryxalis nasuta (Fabr.). — Two beautiful specimens of 

 this wide spread species were shown. They had been re- 

 ceived a few days ago from Alexander Fraser, Esq., Batavia. 

 This being another locality added to the list of places 

 mentioned as habitats of this graceful locust. The position 

 of the eyes, the contrast between the depressed ensiform 

 antennae of this genus and the antennge of most other Orthop- 

 tera, etc., were pointed out. 



(7.) Teratodes monticollis (India) — Was shown with the view 

 of pointing out the specialisations of the thorax in the Locustidce. 



(8.) Schizodactylus monstrosiis (Brulle) (India). — The length 

 of this specimen is about IJ inches, while its antennae are 

 more than 4 inches long, with 240 joints on each. The struc- 

 ture of the tarsi, the form of the mouth organs, and the 

 beautiful spiral folding of the wing covers and wings, when 

 the insect is at rest, were pointed to as outstanding features 

 in this remarkable looking grasshopper. 



(9.) Kallima inachis (India). — Four specimens of the so- 

 called withered leaf butterfly, were shown with the view of 

 indicating the perfect character of the disguise possessed by 

 these insects. The x^revailing tint of the under side of the 

 wings is a light ash-brown, having the very closest resemblance 

 to withered leaves. The midrib and venation of the decay- 

 ing leaf are also closely imitated. In one of the specimens 

 the wing has been broken at the edge, but the rupture has 

 taken place after a fashion characteristic of the break in 

 many leaves. It is not clean, but consists of a saw-Hke 

 irregular edge, which, as it lies on the dark part of the upper 

 surface, forms a perfect resemblance to a broken leaf lying on 

 a bit of bark, or on another leaf not so far gone in decay. 

 The markings on the wings, as round or irregular dots, ragged
