In this paper, Mr. Kirby shows that Mr. Mac Leay's supposed discovery of the 

 minute joint at the base of the claw joint in the Tetramera and Trimera, had been 

 observed by De Geer, and was also mentioned in the ' Introduction to Entomology.'

In this short note, Mr. Kirby admits that he had too hastily assumed that Mr. 

 MacLeay was not aware of De Geer's knowledge of the minute joint in question, and 

 also that the reference to the ' Introduction to Entomology ' ought to have stated that 

 the volume of that work containing the passage above referred to, had not then been 

 published. He further adds, that with De Geer he did not consider the joint in ques- 

 tion as a primary, but as a secondary one.

The species here described are Cremastocheilus variolosus (North America ?), to 

 which is added a detailed description of another species of the same genus, received 

 from Dr. Harris, which Mr. Kirby considered as the real C. castaneae of Knoch. The 

 species of Priocera is named P. pusilla, and supposed to be also a native of North 

 America.

The insects here described are Cnemida (a new genus belonging to the Rutelidae) 

 C. Francilloni, Sparshalli and Curtisii, from Brazil ; Cremastocheilus canaliculars, 

 from Massachussets, with figures of two other previously described species of the same 

 genus, Cymophorus (n. g., near Cremastocheilus) undatus, Campulipus (n. g., allied 

 to Trichius, type Melolontha limbata, Oliv.), Acanthurus (n. g., allied to Trichius, 

 type T. hemipterus, Fabr), Trichius Bigsbii, from Canada; together with a sketch of 

 the distribution of the genus Trichius into seven sections, namely, 1. Legitimi (T. 

 fasciatus, &c.) ; 2. Trichini (T. viridulus, piger, &c.) ; 3. Tetropthalmi (T. suturalis, 

 K., n. s., Java) ; 4. Archimedii (T. Delta) ; 5. Euclidii (T. triangulum) ; 6. Aleuro-

The species here described are Scarabaeus femoralis, a gigantic species of sacred 

 beetle, from Nigritia (Soudan), Drepanocerus (a new and curious genus, allied to

 from the same Cape, Chrysina (a new genus of Rutelida?), C. Peruviana, Emcephalus 

 (a new genus allied to Helseus), E. gibbosus and Adelium Hopii. Most of these 

 insects are beautifully figured by Sowerby.
