328 Mr. Westwood’s further Remarks on Clinidium, &c. 
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 obserying 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 unlooked 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 benignum” (Encycl. Meth. Vol. 10, 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. ‘* Ils restent accouples pendant deux ou trois minutes et 
‘© quelque fois plus long temps.”’ 
In page 218 I have observed that the geographical situation of 
Rhysodes and 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 Dumeril 
in his ‘* Considerations Generales’? having placed them between the 
Bostrichide and Trogositide, as “‘ genres anomaux de Tetraméres.”’ 
Consult Mr. MacLeay’s Hore Entomologice, p. 1. Appendix t. on 
the supposed affinity of Trogosita withthe Lucanide. 
I find that in my remarks upon Megagnathus, | 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 cerulea, enea, &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 Trogosite.
