and H. Lankester ; Panama (including Chiriqui, the Pearl Is., and Taboga)—G. C. 
Champion, EK. Trotsch, H. Ribbe, and A. Boucard. The Hymenoptera examined 
and reported upon by P. Cameron mainly consisted of the collections made by 
G. C. Champion in Guatemala and Panama, and by G. F. Gaumer in Yucatan, most 
of the vast number of specimens obtained in Mexico by H. H. Smith having been 
received too late to be included; it must be remembered, too, that the bees and social 
wasps have not been dealt with. ‘The Lepidoptera, apart from the specimens captured 
by Salvin or myself, were obtained from the collectors who supplied us with the other 
insects; very extensive additions to both the Rhopalocera and Heterocera have, 
however, been made since 1900, especially by W. Schaus, who visited Mexico and 
Costa Rica in search of them. The Diptera examined were comparatively few in 
number, though H. H. Smith did his best in Mexico to make up the deficiency. The 
Rhynchota were very numerous, both in Heteroptera and Homoptera, as regards 
Guatemala and Panama, but till H. H. Smith went to Mexico we had received 
very little from that country, the habitat of most of the previously described 
species from our region. The Orthoptera, again, were few in number, none of our 
collectors having paid very much attention to them. The Arachnids were mainly 
supplied by H. H. Smith (Mexico), F. Sarg (Guatemala), and G. C. Champion 
(Panama); the Acaridea, however, were mainly procured by, and belonged to, 
Dr. Otto Stoll. In the Botany, the collections made by Mr. and Mrs. Salvin were 
used by Mr. Hemsley, but the study of the plants was almost entirely made from 
material contained in the Herbarium at Kew, including that which we had previously 
sent from Guatemala. Mr. Maudslay’s work on the Archeology was based on his own 
observations on the various ruins visited during his sojourn in the country; Mr. J. 8. 
‘Goodman, in his Appendix to this subject, gives an account of the system he used to 
decipher the Archaic Maya Inscriptions, which relate to a series of calendars. | 
Mr. Champion’s Itinerary is given on pp. 46-54, and the places he visited in 
Guatemala are easily traceable on Map 8; we are unable, however, to find space 
on our other maps to include all the Mexican localities quoted in the Zoology and 
Botany, some of which, indeed, cannot now be traced *. 
* It must be remembered that nearly all the names commencing with ‘San,’ ‘ Santo,’ and ‘ Santa’ have 
been used over and over again in the different States. The spelling of some of the others has been emended 
on our Maps to agree with official Mexican diréctories.
