of the pronotum somewhat sparingly punctured. Scutellum with a few deep punctures, and very faintly 
and transversely wrinkled towards apex. Corium rather finely and thickly punctured ; membrane ochra- 
ceous, posterior margin pale yellow. Body beneath concolorous, finely and sparingly punctured. Rostrum 
reddish brown. Legs pitchy brown, tarsi somewhat paler. . 
Long. 12 millim., lat. 7 millim. 
Hab. Costa Rica, Trazu, 6000 to 7000 feet (Rogers). ’ 
Allied to C. teter, Spin., but at once distinguished by the large excavation “of the 
pronotum. bd ° 
Note.—The figure does not sufficiently show the punctuation of the pronotum and 
scutellum.

I have followed Prof. Uhler in placing C. castaneus, A. & S., as a synonym of this 
species, though Stal, who is seldom in error, considered it distinct. I doso because Prof. 
Uhler has had so many specimens through his hands, and also from the examination of 
other specimens kindly lent me by Dr. Signoret. Prof. Uhler, however, seems to have 
fallen into confusion as to the habitat of this species. In 1875 he records it as from 
Texas‘; in 1877 he writes ® :—“ This species has not yet been brought from Texas or the 
region west of the great plains, unless the next species (C. obtwsus) shall prove to be a 
form of it. The differences separating them seem ample; but long series from many 
localities may yield the intermediate links.” It is at least remarkable if C. mutabilis, 
recorded as it is by Prof. Uhler‘ as from South Carolina, Georgia, Florida, Guiana, 
and Brazil, should yet be absent in the intervening region of Central America, whilst 
he gives Mexico as a habitat for his C. obtusus. Berg also describes it as a very variable 
species in South America.

Dr. Signoret has forwarded me a copy of his description of this genus (in proof), with 
the date December 1879. It is founded for the reception of the Cyrtomenus emarginatus, —
