328 Mr. Westwood's further Remarks on Clinidium, 5yc. 



consequently been anxious to corroborate my remarks by a renewed 

 examination of the same species of Spiders in their webs. I have not, 

 however, been fortunate in again observing the act of impregnation ; but 

 at one time during the last autumn I perceived no less than six pairs 

 engaged on separate webs in preparatory dalliance according to the 

 Arachnidan method of courtship. This of itself (although not altogether 

 confirmatory of my former observation) is strongly corroborative of its 

 correctness ; but as the pleasure resulting from the unlocked for confirma- 

 tion of our observations when doubted, ranks next to that arising from 

 novel discoveries, I was gratified in meeting with the interesting details 

 given by M. Latreille of M. Walckenaer's observations relative to the 

 " accouplement de Theridon benignurn'* (Encycl. Meth. Vol. 1 0, p. 624). 

 I shall merely extract the following short passage as entirely removing all 

 doubt upon the most material fact advanced in my paper, which, however, 

 the Reviewer in the " Bulletin des Sciences Naturelles" has entirely 

 overlooked. " lis restent accouples pendant deux ou trois minutes et 

 '* quelqufe fois plus long temps." 



In page 218 I have observed that the geographical situation of 

 Rhjsodes diXid Clinidium appeared distinct ; such is not, however, the case. 

 I have observed in the cabinet of the Baron Dejean six or eight species of 

 the former genus, several of which were collected in Brazil by M. La 

 Cordaire. Vide Annales des Sciences Naturelles. 



The doubtful situation of Cucujus and Spondylis is shewn by Duraeril 

 in his " Considerations Generales" having placed them between the 

 BostrichidcB and Trogositidce, as " genres anomaux de Tetrameres." 



Consult Mr. MacLeay's Horse Entomologies, p. 1. Appendix t. on 

 the supposed affinity of Trogosita with the LucanidcB. 



I find that in my remarks upon Megagnathus, I had overlooked Sturm's 

 figure of the underside of the head. It is however far from being in his 

 happy style. 



The propriety of the generic separation of Trogosita ccerulea, tsnea, &c. 

 under the name of Temnoscheila is fully confirmed by the observations 

 of M. La Cordaire, in his account of the habits of Brazilian Beetles, 

 (Annales des Sciences Naturelles.) The economy being distinct from the 

 true Trogosita.
