Vol. XXV] ENTOMOLOGICAL NEWS. 295 



The ovipositor of the allotype is 16.8 mm. long and 3.1 mm. in great- 

 est width. 



The tegminal measurements are given for these organs in their con- 

 vex natural condition ; were the tegmina flattened out a decided increase 

 in length and width would result. The type is about the average for 

 the series of males taken by the authors ; the male taken earlier in the 

 season with the allotype is very large. 



In life the specimens were jade green; this color has become pale on 

 the body and limbs in the majority of dried specimens. The eyes are 

 walnut brown. 



The present species is known only from the Chisos Moun- 

 tains, situated in the southern portion of the Great Bend reg- 

 ion of the Rio Grande in western Texas. The following field 

 notes were taken : "This species is everywhere on the hillsides 

 above 4700 feet elevation in low oaks (15 to 25 feet in height) 

 and at dusk the males begin their incessant song which is con- 

 tinued through the night. This song consists of a single rasp- 

 ing note, quuck — quuck — quuck, repeated incessantly and very 

 deliberately. One was startled into giving this note in the 

 early afternoon of a cloudless day when a rifle was fired over 

 the canon. The specimens are found in the trees usually near 

 the lower branches, perched upon the twigs among the leaves ; 

 they are very hard to locate, but when the collector has climbed 

 into the tree an individual will usually recommence its song if 

 he keeps still under it for a few minutes. When closely ap- 

 proached they invariably leap clumsily into space, unless 

 quickly seized, and upon hitting the ground at once begin to 

 crawl away. When seized they often utter their note in an 

 irritated manner."
