Africa and its adjacent islands ; some few species 

 are met within Madagascar. Mel. gibba, lineata, 

 and picea described by Fabricius belong to this 

 genus Trochalus. 



Sp. 58 Erythrocephala. — Belonging to the genus 

 Apogonia, Kirby. The founder of this well cha- 

 racterized genus doubts the country to which the 

 type belongs. I give my opinion that it inhabits 

 the East Indies, as there are several species allied 

 to it in my collection from Madras and Singapore. 

 Three were described by me from General Hard- 

 wicke's collection, viz. Apogonia nigricans, senes- 

 cens, and brunnea. Vide page 23, of the Zoological 

 Miscellany. 



Sp. 62. Rufa. — This singular insect appears to 

 be a form well worthy of being made the type of a 

 new genus. It is in the Banksian cabinet. 



Sp. 63 & 64. Festiva.— Mr. MacLeay in the 

 Appendix to Captain King's Narrative of a Survey 

 of the Coasts of Australia, justly considers this in- 

 sect as the type of a new genus allied to Serica. 

 I suggest the adoption of the term Calonota, to 

 include all the Hydrobiiform Sericidse. They seem 

 to be peculiar to New Holland. Vide the details 

 of the genus in the concluding part of this 

 Fasciculus among the new genera.
