Hence in Galapagos leaving out the 2 probably introduced, we have 24 insects belonging to 10 of the 13 sections, (followed by Mr. Woll Wollaston) & these insects were collected during about 6 (?) weeks work, so it shows that pretty well distributed over whole class. The 24 species belong 18 genera. ie each genus has on average 1.33 species — or 3 genera wd have 4 species; & these 18 genera belong to 17 Families
The Atrachelia (or Heteromera) have 9 species
The Geodephaga & Rhyncophora 3 each.—
(In Madeira the Atrachelia only 1/2 of Geodephaga, which is less than Rhyncophora & this less than the Brachelytra.—)
