49G ANALYSIS. 



him to set apart, under the name of Jlctmophorus, the 

 aboveraentioned insects in his cabinet, and to add to their 

 T\umher S. pilularius, Geojftoyi and Schajferi. "It is 

 true," he observes, " that these three species, and particu- 

 larly the last, in which the middle coxse are wide apart, 

 quit in some measure the habitus of S. Sacer and its affi- 

 nities ; yet they appear to me to be better placed in this 

 genus than in any other." 



In the year which followed the publication of the Ento- 

 mologische Versuche, appeared Sturm's Entomologisches- 

 Handbuch, in which the genus proposed by Creutzer is 

 adopted, and scientific characters are assigned to it. Sturm, 

 however, adds S. volvens arid sinuatus to the species spe- 

 cified by his predecessor, merely observing that volvens 

 and Schaff'eri qviit in some degree the general habitus of 

 the others. He therefore divides his genus Actinophorus 

 into two families ; the first consisting of those species 

 which have the middle feet near to each other at the base, 

 and the second containing those which have them widely 

 apart. The first family is the earliest, and indeed the only 

 distinct specification of the genus Scarabceus as here given, 

 that I have met with. When we consider the small num- 

 ber of species with which these two Germans were ac- 

 quainted, it is really surprising that they should have ac- 

 quitted themselves so well. They certainly aie the first 

 discoverers of the present natural group, of which I shall 

 now indicate the construction.
