Sp. 22. Striatus. — This insect forms the type of 

 Mr. W. Sharpe MacLeay's genus Figulus ; he states 

 that it occurs in the East Indies and in the Island

 gascar and the Islands of Mauritius and Bourbon 

 (which, geographically, may be considered as con- 

 nected more intimately with Africa than Asia) 

 appear in the entomological character of their 

 genera to unite the insects of the two continents. 

 They possess, however, types of form, which seem 

 (as far as I have yet had an opportunity of judging) 

 peculiar to these islands. I am exceedingly anxious 

 to ascertain, if any traces of deviation from typical 

 forms of the insects of the African continent have 

 been observed in the smaller islands on the coast of 

 the Red Sea. It is probable that a slight deviation 

 in these localities may be observed. To this genus 

 belong Fig. ebenus of King from Madagascar, 

 F. Ovis D. J. from Senegal* and also F. regularis of 

 Westwood from New Holland. The genus appears 

 to be confined in its range to Africa, Asia, and 

 Australia. 



Sp. 23. Caraboides. — The type of the genus 

 Platycerus of Latreille, Lucanus rufipes Fab. is per- 

 haps only a variety of PL caraboides. I possess a 

 second species from North America, which belongs
