270 THE ENTOMOLOGIST. 
Gueneei is generally recognized as a form of L. testacea, but 
it might equally well be set down as a form of L. nickerliit. The 
Lancashire specimens, in fact, certainly seem to connect gueneet 
with nickerlii, and until it can be shown that these two can be 
separated one from the other, and from the Lancashire Luperina 
on structural differences in genitalia, I am inclined to accept all 
three as forms of one species. 
If it should subsequently be established that Mr. Baxter’s 
Luperina is specifically distinct from both nickerliit and gueneet, 
then it will have to be known as ZL. incerta, Tutt, and I propose 
to name the paler greyish specimens taken this year ab. bazteri. 
Some figures of the moths are being prepared, and these, 
together with drawings of Mr. Pierce’s preparations of the geni- 
talia, will be published in the ‘Entomologist ’ for December. 
THE ORDERS OF INSECTA. 
By D. SHarp, M.A., M.B., F.R.S., &e. 
Tue question of the number of Orders that should be adopted 
in the Class Insecta has been much discussed, and a considerable 
- variety of views expressed about it. The subject has just been 
treated by Handlirsch in his great work on Fossil Insects, and 
it will no doubt be of interest to enumerate the Orders he adopts 
we existing insects. They amount to no fewer than thirty- 
Ve, viz. :— 
1. Arthropleona. 18. Mantoidea. 25. Plectoptera. 
2. Symphypleona. 14. Blattoidea. 26. Megaloptera. 
3. Dicellura. 15. Isoptera. 27. Raphidioidea. 
4, Rhabdura. 16. Corrodentia. 28. Neuroptera. 
5. Machiloidea. 17. Mallophaga. 29. Panorpate. 
6. Lepismoidea. 18. Siphunculata. 30. Phryganoidea. 
7. Gastrotheoidea. 19. Hymenoptera. 381. Lepidoptera. 
8. Orthoptera. 20. Coleoptera. 32. Diptera. 
9. Phasmoidea. 21. Strepsiptera. 33. Suctoria. 
10. Dermaptera. 22. Embioidea. 34. Hemiptera. 
11. Diploglossata. 23. Perlaria. 35. Homoptera. 
12. Thysanoptera. 24. Odonata. 
A few words of explanation and comment may be acceptable 
about this very formidable list. Nos. 1 and 2 are the two great 
divisions of the old Order Collembola; 8 and 4 are the Campodeid 
forms, Japyx, Campodea, &e.; 5,6, and7 are divisions of Thysa- 
nura (7 being altogether doubtful), the old name Thysanura being 
still used by Handlirsch as that of a ‘Class’? composed of these 
three Orders; 8, Handlirsch limits the Orthoptera to the old 
Saltatoria, treating each of the other great divisions (viz. 9, 10, 
11, 13, and 14 of our list) as a separate Order, and interpolating
