STUDIES IN COSTA RICAN DERMAPTERA AND 
ORTHOPTERA 
BY JAMES A. G. REHX 
M}" int('r(\st in the ( )i-tliopterous fauna of ( 'osta Riea extends 
haek to the year 1!)()3, M'hen in three papei’s* were reeorded the 
first colleetions fi'oni that country examined ))y me. Since that 
time much additional (fosta Rican material has passed into my 
hands, many si)ecies have been recorded and numerous ones 
described, l)ut a very large i)ortion of these collections is as yet 
unreported. Aluch progress has l)cen made in the development 
of our knowledge of the Dermaiitera and Orthoptera of Alexico, 
Central America and northwestern South America, and a far 
Ijetter groundwoi’k for resumed study is now available. 
h'or a number of years one of my greatest desires has been to 
prei)are a comjjrehensive catalogue and faunistic study of 
t'osta Rican I)(M-maptcra and Orthoptera. For a tropical re- 
gion of greatly diversified conditions, the fauna of ('osta Rica 
is as rich as, and, relatively speaking, i)robal)ly Ijettcr known 
than, that of any other country of similar size within the Amer- 
ican tropics. There exists a i)ossil)ility of the realization of my 
desire in the not too distant future, and a definite amount of 
study time is now Ijeing given to the extensive collections in 
hand. These I hope to l)e able to supplement, before final 
publication, with additic)nal, personally secured, material and 
o1)servations. 
As it ap]jears desirable to make known new forms recognized, 
and important changes or synonymy necc'ssitated as the work 
progresses, papei’s under the title here givcui will Ix' bi'ought 
out from time to time.
