204 SYSTEMATIC ARRANGEMENT. 



number of simple eyes, the only kind with which 

 these larvse are provided, varies from one to six ; the 

 former is exemplified by Telephorus, the latter by 

 Carabus. In the larvse of Cicindelae the two posterior 

 ones have a red pupil surrounded by a pale iris. 

 The larvaa of many different kinds commonly termed 

 grubs by husbandmen are productive of great injury 

 to cultivated plants, both when growing, and after 

 they have been harvested. 



Of all the orders perhaps this is the one that has 

 been most studied, a preference which it owes to the 

 great beauty of many of its foreign species, the end- 

 less diversity and singularity of their forms, the dis- 

 tinctness of their external parts, and the ease with 

 which they can be preserved in unimpaired beauty 

 for an indefinite length of time, as well as other con- 

 siderations, calculated to recommend them to notice. 

 It is partly from the zeal with which they have been 

 sought after, that their number has always appeared 

 so much greater than that of the other orders, which, 

 now that they have attracted more attention, are 

 found to make a nearer approach to them in this re- 

 spect than was formerly imagined; still, however, 

 the preserved examples are considerably most nume- 

 rous, as is likewise, there can be no doubt, their ab- 

 solute amount in nature. The collection of the Count 

 De Jean has been augmented, in the short period 

 that has elapsed since we last mentioned the amount 

 of its contents, to nearly 23,000 species, and it is 

 conjectured that about 6000 or 7000 others exist in 

 the Parisian cabinets. The collection of beetles in
