11 Legs, anterior and middle pair with a foliaceous append- 

 age on the femora and tibiae, that on the femur extending 

 from the middle to the end, the appendage on the tibiae 

 narrower, and at the base — all the femora with two rows of 

 spines. Tibiae of hind legs with one row of spines in front 

 and two behind." 



A few words may describe the solitary specimen of the 

 species : — 



" Tegmina and part of wings covered by them, like a brown 

 withered leaf. Wings deep black, edge near the lobe 

 spotted with white. A small, smooth, black spot near the 

 posterior edge of tegmina. The thick jaws are yellow at 

 the base, and black inside and at the apex. 



" Length front of head to end of oviscapt, 3 inches. 



" Length of wings, 1 inch. 



" Expanse of tegmina, 3 inches and 1 line. 



" Length of fore legs, 2 inches and C lines. 



" Length of hind legs, 4 inches and 3 lines. 



" Hah. Old Calabar. — Its large, powerful head and jaws 

 show that it must be a voracious feeder of leaves of a 

 stronger texture than those of our shrubs and trees." 



" Oi the Family Locustidce, which contains the migratory 

 locusts and our grasshoppers, there is a curious short-winged 

 insect, allied to Petasia and Phymateus. The tegmina and 

 wings are only about half the length of the body. 



" A brilliant little blue and green Chrysis* 



" A curious black bee,* with black wings, thorax below 

 whitish, legs hairy and rough, and very long maxillae. He 

 hoped Dr Smith would send it to Mr Frederick Smith of 

 the British Museum, who has such a perfect knowledge of 

 the Hymenoptera. 



" Of the Diptera, there are two specimens ol a most cosmo- 

 polite genus, Tabanus* flies whose attacks on cattle are so 



* Dr Smith has since sent the bee to Mr F. Smith, and is informed that 

 it is the female of a new species of Anthophora. The Tabanus, Mr Smith also 

 says, is the T. tibialis ; and the beetle mentioned above is the Stilbum lyncea.
