Show 1894.] HEMIPTERA-HETEROPTERA OF GRENADA. 175 Corium and clavus coarsely, deeply punctate in lines, becoming 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 tibia? not grooved. Length to end of venter, 3 8§-9, § 10-10| mm.; width of pronotum 3 5-5\, 2 5g-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 Gay estate, on the leeward side of the island of Grenada. PIEZODORUS, Fieber. PlEZODORUS GUILDINGI (Westw.). Raphigaster guildinii, Westw. Hope Cat. i. p. 31. 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 w7ere 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, Bio, Pernambuco, San Domingo, Cuba, Mexico, and Southern Florida. I have also examined specimens 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 specimens 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. NEZARA, Am. et S. 1. NEZARA MARGINATA (Pal. Beauv.). Pentatoma marginata, Pal. Beauv. Ins. Afr. et Amer. p. 147, pi. 10. fig. 1.
