VERMES. 



Only about 14 species appear to be recorded. 



I repeat that the numbers given for the Arthropoda are in some cases 

 little more than guesses. I have not had time to go through some lists, 

 an examination of which would have enabled me to give more accurate 

 estimates. But except in the case of the four numbers to which a note of 

 interrogation is appended the figures given are I believe a fair approxima- 

 tion to the truth, and the result is one that I think should make Anglo- 

 Indian naturalists endeavour to improve our knowledge of the fauna. It 

 is scarcely creditable that in a perfectly accessible country, with facilities 

 for travelling and for living in different parts of the area unrivalled within 

 the tropics, we should remain so ignorant of the zoology. It is ridiculous 

 to suppose that the Indian Goleoptera are scarcely more numerous than the 

 Lepidoptera, that the Hymenopiera (which very probably rival and may 

 excel, each of the other orders) are only between \ and -A- as numerous, or 

 that the Neuroptera, of which, Mr. McLachlan tells me, about 1000 are 

 known from Europe are only represented by 350 species. As to the spiders, 

 it is no exaggeration to say that in most parts of India 108 species might 

 be collected in a few days' search. It is to be hoped that the next five 

 years will witness a very considerable increase in our knowledge of the 

 fauna of India.

Euripus chtnamoheus, n. sp., PI. IV, Fig. 4. 



? . Anterior wings above purplish black-brown darkest at the base and 

 along the edges and glossed with steel-blue on the disk, with a conspicuous 

 suboval or subtriangular patch of changeable lilac-blue divided by the dark 

 veins, commencing broadly just in front of the ultimate subcostal fork and 

 rapidly narrowing to the inner angle, and with an indistinct submarginal 

 series of small roundish white spots placed upon the inner edge of the narrow 

 black-brown outer border and extending from the inner angle up to the 

 third median veinlet.
