genera. Morphidae are well represented by the genera Ama- 

 thusia, Zeuxidia, Discophora, and Thaumantis, some of the 

 species of which almost equal the grand South American 

 Morphos. The Nymphalidse furnish us with a host of charac- 

 teristic genera, among the most remarkable of which are, 

 Terinos, Adolias, Cethosia, Cyrestis, Limenitis, and Nymphalis, 

 all abounding in beautiful species. Among the LycsenidsB are 

 a number of fine groups, among which we may mention Ilerda, 

 Myrina, Deudoryx, Aphneus, lolaics, and AmUypodia, as charac- 

 teristic examples. The Pieridse furnish many fine forms, such 

 as Thyca, Iphias, Thestias, Eronia, Prioneris, and Dercas, the last 

 two being peculiar. The Papilionidae are unsurpassed in the 

 world, presenting such grand genera as Teinopalpus and Bhu- 

 tanitis; the yellow-marked Omithoptercc ; the superb "Brookiana;" 

 the elegant Leptocercus; and Papilios of the "Coon," "Philo- 

 xenus," " Menmon," " Protenor," and especially the ' green-and- 

 gold-dusted ' " Paris " groups. 



The Moths call for no special observations, except to notice 

 the existence in Northern India of a number of forms which 

 resemble in a striking manner some of the most remarkable 

 of the above mentioned groups of the genus Papilio, espe- 

 cially the "Protenor" group, which there is reason to believe is 

 protected by a peculiar smell or taste like the Eeliconias and 

 Danaidse. 



Coleoptera. — The most characteristic Oriental form of the 

 Cicindelidse or tiger beetles, is undoubtedly the elegant genus 

 Collyris, which is found over the whole region and is almost 

 confined to it. Less abundant, but equally characteristic, is the 

 wingless ant-like Tricondyla. Two small genera Apteroessa and 

 Dromicidia are confined to the Indian Peninsula, while Therates 

 only occurs in the Malayan sub-region. 



The Carabidas, or ground carnivorous beetles, are so numerous 

 that we can only notice a few of the more remarkable and 

 characteristic forms. The wonderful Mormolyce of the Indo- 

 Malay sub-region, stands pre-eminent for singularity in the 

 entire family. Thyreopterus, Orthogonius, Gatascopus, and Peri- 

 callus are very characteristic forms, as well as Planetes and
