THE LEAF AND TWIG MINING BUPRESTID BEETLES 
OF MEXICO AND CENTRAL AMERICA. 
By Warren S. FIsHeEr, 
Of the Bureau of Entomology, United States Department of Agriculture. 
This paper is the result of a study of the Buprestid beetles of the 
Tribes Agrilini (Group Trachytes) and Mastogenini from Mexico and 
Central America, in the collection of the United States National 
Museum. In 1910 the Smithsonian Institution organized a Biologi- 
cal Survey for the study of the fauna of the Panama Canal Zone, 
which was made during the winter of 1910-11. The greater part of 
the material recorded in the present paper has been collected by 
Messrs. 2. A. Schwarz and August Busck, who were detailed by the 
Bureau of Entomology to make a study of the insect fauna in con- 
nection with the survey. 
The present paper includes all of the described species of these 
two groups from Mexico and Central America, with the exception of 
a few species which are unknown to the writer, and which have the 
descriptions so incomplete as to make it impossible to correlate the 
characters given in the original descriptons with those used in the 
keys. One genus and 42 species are described as new, and the types 
of all these new species are in the National Museum. Quite a number 
of the old species are not represented in the National Museum Col- 
lection, but to make the paper more complete these have been 
included in the keys solely upon the characters given in the original 
descriptons, and also their distribution, so far as known from the 
literature. The keys are not intended to show the taxonomic relation 
of the species, but simply to assist in their identification. It has 
been impossible to show the true relationship of the species at the 
present time, on account of not haying sufficient material available 
for study, but it is hoped that it will stimulate the collecting of 
these small interesting beetles, which can be taken by sweeping the 
flowers and foliage of miscellaneous plants.
