altogether on the grounds of "' priority." In orders and suborders, 

 it is almost, if not quite impossible, to achieve this, but if it must 

 be enforced, then, unless it be used to supersede " Physapoda," 

 " Siphonata " must be used for " Homoptera." It must be noted, 

 however, that Siphonata and Proboscidea are equivalent together 

 to Homoptera. I think that when two names, such as Hemiptera 

 and Eyngota (now usually spelt Ehynchota) are practically 

 coterminous, the earlier should have the preference. 



The synonymy I propose is therefore : — 



Order Hemiptera, 1758 (type Cimex) = Ryngota, Fabricius, 

 1775. 



Suborder 1. Heteroptbra, Latreille, 1802 (type Cimex) — 

 Dermaptera, Pietzius, 1783 — Hemiptera, Westwood, 1838. 



Suborder 2. Homoptera, Latreille, 1802 (type Cicada) = 

 Siphonata and Proboscidea, Eetzius, 1783 (type Aphis and 

 Coccus, respectively). 



Hemipterists have almost always cited the date of publication 

 of Fieber's ' Europaischen Hemiptera' as 1861, for the whole of 

 the volume, though Hagen, indeed, mentions three hefts as 

 follows :— Heft i., pp. 16 and 108 (1860); heft ii., pp. 109 to 

 30i (1861) : heft iii., pp. 305 to 444 (1861). 



Unless there were two different editions, which is hardly 

 likely, Hagen has made a mistake. When visiting my friend 

 Mr. J. R. de la Torre Bueno, in New York, in 1903, my 

 attention was drawn to a copy of this work in the original covers, 

 the lirst one I had seen. Mr. Bueno has now refreshed my 

 memory, and I find that the proper dates are : — Heft i., pp. 1 

 and 112, and two Plates (1860). The " 16 pp." are part of the 

 " 108" (or rather 112). Hefts ii. and iii. (in one), pp. 113 to 

 304 (1861); heft iv., pp. 305 to 444, and iii. to vi. (the 

 "Vorrede") (1861). No further details are to hand, but it is 

 probable that heft i. was published early in 1860, as the 

 " Vorrede " is dated October, 1859. One hundred and seventy- 

 eight Fieberian genera and thirty-two species are thus to be dated 

 1860, instead of 1861, as regards this book.

The species of Amauronematus do not appear so common, 

 and I have only found A. fallax at Ipswich and Tuddenham Fen 

 on birch in May; A. vidiiatus at Wicken, Tuddenham, and 

 Brandon in June and July, by sweeping low plants ; and A. vit- 

 tatas, which I believe Dr. Cassal has also found at Ballaugh, in
