genera, Morpliidse are well represented by tlie genera Ama- 

 ihusia, 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, 

 Teriiios, Adolias, Cetliosia, Cyrestis, Limcnitis, and JS^i/mphalis, 

 all abounding in beautiful species. Among the Lyccenidse are 

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

 Myrina, Deudoryx, Aphncus, lolaus, and Amljlypodia, as charac- 

 teristic examples. The Pieridne furnish many fine forms, such 

 as Thyca, Ipliias, Thestias, Eronia, Prioneris, and Doras, the last 

 two being peculiar. The Papilionidre are unsurpassed in the 

 world, presenting such grand genera as TeinojKdjms and BJm- 

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

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

 xenus," " j\Iemnon," " Protenor," and especially the ' green-and- 

 gold-dusted ' " Paris " groups. 



Tlie 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 Heliconias and 

 Danaidce. 



Colcoptera. — The most characteristic Oriental form of the 

 CicindelidjB 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 Theratcs 

 only occurs in the ^lalayan sub-region. 



The Carabidffi, or ground carnivorous beetles, are so numerous 

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

 characteristic forms. The wonderful Mormolycc of the Indo- 

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

 entire family. Thyreopterus, Orthogonius^ Catascopus, and Peri- 

 calltis are very characteristic forms, as well as Planctcfi and
