covered with fine hairs is the ligula, and the two delicate pieces in- 

 serted upon its base are the paraglossse. 



No. 11. — Is part of the wing of a Musquito. The nervures have 

 delicate scales attached to them on both sides of the wing, in addi- 

 tion to which there is a beautiful fringe of larger scales all round 

 the margin. The smaller scales as well as those from the body of 

 the musquito were used as test objects. They require a good 

 glass to show them properly. 



No. 12. — Is the mouth of the Larva of the Ant-lion known to 

 young people in India, as the Koolinary. This insect makes a 

 small pit in the form of an inverted cone, in the bottom of which it 

 sits waiting to seize any unfortunate ant or other insect that may 

 fall over the hedge of the pit. But should its victim attempt to 

 escape, the ant-lion immediately begins to jerk out the sand from 

 the bottom of the pit, which not only makes it deeper but increases 

 the steepness of the sides, and the escaping insect is probably hit 

 and brought down again. 



The Larva bears no resemblance to the perfect insect, which is 

 very beautiful, and resembles the Dragon flies. 



No. 13. — Is a scale from the wing of the Morpho menelaus, a 

 beautiful American Butterfly. It has been long used as a test 

 object. The photograph shows the appearance of the scale when 

 damp has penetrated between the slide and the thin glass cover, 

 as is the case after a short time with nearly all the dry mounted 

 objects received from England, when this has taken place the true 

 structure cannot be made out. 



No. 14. — Is a magnified view of a piece of Arnee Muslin, for 8 

 yards of which 100 Rupees were paid. The irregularity in the 

 size of the threads and the inequality of their distances is very 

 evident. It would have been instructive to have compared a piece 

 of the best English Muslin with this, but I had not time to do so. 



No. 15. — Is a Coccus, produced in great numbers in my Library 

 from Lac found upon a Mango Tree in my garden. I believe it is 

 the Larva state of the Insect, but am not certain. 



No. 16. — Is the Exuviae or cast off skin of the Bed-bug Cimex 

 lectularius. The trophi of the Bug consists of a rostrum in which
