Show 740 MR. C J. GAHAN ON COLEOPTERA [Dec. 5, seem to form two series on each side in the female, one series each side in the male. The latter sex is also characterized by a rather deep incision in the last ventral segment, and by the presence of a small tuft of hairs lodged in a slight depression near the middle of the penultimate ventral segment. SCARABAEIDAE. 3. T R O X MELANCHOLICUS, FS.hr. 4. TROCHALUS, sp. 5. ANOMALA, sp. 6. POPILLIA SERENA, Har. A number of specimens varying considerably in colour seem to be referable to this species. The shades of colour occurring in different individuals include leaf-green, dark blue, and bluish green; while a few even present coppery or slightly brassy tints. No difference of structure or punctuation accompanies these variations of colour, so that all the specimens doubtless belong to the same species. 7. POPILLIA DISTINGUENDA, Fairm. Two examples of this form were taken at Zomba which with difficulty only could be distinguished from a variety of the Chinese species Popillia castanoptera, Hope. They differ from the described type of P. distinguenda, Fairm., in having a dark band along the outer margin of each elytron. 8. GOLIATHUS ALBOSIGNATUS, Bohem. One example. Recent authorities seem agreed in considering this species distinct from G. kirkianus, Gray. Its presence as far north as Zomba shows, however, that it has a wider, distribution than has been previously attributed to it, and that it occurs in practically the same locality as Gray's species. 9. RANZANIA PETERSIANA, Klug. 10. NEPTUNIDES POLYCHROUS, Thorns. 11. CERATORHINA PRINCEPS, Oberth. Ceratorhina princeps, Oberth. Bull. Soc. Ent. Fr. 18S0, p. cxix ; Bates, Ent. Mo. Mag. xviii. p. 156. This species is barely more than named by Oberthiir in the work cited. The characters of the male are described by Bates. In the majority of the specimens taken at Zomba, forming a tolerably complete series, two somewhat evanescent greenish spots are to be seen on the pronotum. 12. HETERORHINA ELONGATA, Bates. Heterorhina elongata, Bates, Ent. Mo. Mag. xviii. p. 157. One example. 13. GENYODONTA QUADRICORNIS, 0. Janson. |
