1894.] HEMIPTERA-HETEROPTERA OF GRENADA. 175 



Corium and elavus coarsely, deeply punctate in lines, becoming more 

 dense and irregular on the cuneal space ; the costa with about three 

 lines of punctures, and a line of smaller ones on the inner suture ; 

 disk along the suture broadly smooth; membrane transparent, 

 sometimes a little tinged with rufous ; wings also more or less 

 rufous or yellowish. Tergum often reddish, with the connexivum 

 pale green, more or less yellowish or reddish, highly polished, 

 remotely and finely punctate, angles of the posterior segment 

 acute. Legs deep green, with the tibiae not grooved. 



Length to end of venter, c? 8|— 9, § 10-KH mm. ; width of 

 pronotum c?5-5|, $ 5|-6. 



Eighteen specimens of this species were collected by Mr. H. H. 

 Smith, who gives the following notes concerning their capture : — 

 " Swept from herbage in open weedy places, at an altitude of 

 250 feet above the sea, on April 3 ; about cocoa orchards, on 

 herbage, April 5 ; came to light at night, August 6-10, at an 

 altitude of 250 feet; also August 25-30; August 26-31, beaten 

 from herbage ; September 3-10, came to light at night, at an altitude 

 of 300 feet." These were collected on the Mount Gray estate, on 

 the leeward side of the island of Grenada.

Specimens of both sexes and of two varieties (i. e. degrees of 

 maturity) were found at Balthazar and other places. At the 

 former they were taken, March 23, from herbage, at night. Others 

 were found at St. George's, August 22, on open swampy places, 

 upon herbage. 



This species has an extensive distribution. In my collection 

 there are specimens from Paraguay, B-io, Pernambuco, San Domingo, 

 Cuba, Mexico, and Southern Florida. I have also examined spe- 

 cimens from Jamaica, Trinidad, and Central America. 



This species varies in size, convexity, and depth of colour. Some 

 of these differences are due to the degree of maturity of the speci- 

 mens at the time of their capture. Immature specimens are a 

 pale faded greenish, either with or without the red band across the 

 pronotum. When the dorsum of the mesonotum shows through 

 the integument the base of the pronotum appears black, but when 

 the chitinous cover of the pronotum is maturely indurated no 

 blackish spot appears across the base of this segment. Specimens 

 when fresh and mature are of a clear green colour.
