This is a posthumous work, for first part of which cf. op. cit 1882, 
edited by Jekel, who makes some introductory remarks and criticisms, 
pointing out specially that the genus Sphenophorus , after the dismember¬

The number of ovarian tubes in this species is increased to twenty. 
The sexual structures of the female indicate a lower stage of evolution 
than in other Lepidoptera. Description of peculiarities of structure in 
the external parts, $ . Existence of an undoubted ovipositor ( T'meola 
biselliella , Humm. possesses one of still higher organization). The 
number of vesiculee seminales in the $ is apparently correlated with that 
of the ovarian tubes of the female. The increase in the number of the 
vesiculse seminales is of much importance, as indicating a link to the 
Phryganidce. Description of outer parts of the $ . A natural nomen¬ 
clature of these parts is urgently required, that of Burgess (for Daiiais 
arcliippus ) commended. Need of fresh investigations as to “ Micro- 
Lepidoptera which may result in the breaking up of the group. These 
are the chief points of this suggestive memoir. A few other insects are 
mentioned, especially Sesia scoliiforniis and S. hylceiformis ; and in respect 
to Carabus, he says that he has found important individual variations in 
the number of the ovarian tubes in different species.

This and the following paper being only indirectly entomological, it is 
sufficient to mention their titles. The above discusses at length the diffe¬ 
rent theories as to the nature of the disease so fatal to silkworms.
