This fine species appears nearly allied to the Centris versicolor, Fabr. (Syst. Piez. 359. 23.) which is an inhabitant of the Islands of America, but which is described thus, "thorace hirto cinerascente, abdomine cyaneo, ano rufescente." ECHINOMYIA HIRTA. Plate XLV. fig. 4. ORDER: Diptera. SECTION: Athericera. FAMILY: Muscidæ, _Leach_. GENUS. ECHINOMYIA, _Dumeril_. Tachina, _Fabr._ Musca, _Drury_. ECHINOMYIA HIRTA. Atra; alis obscuris, abdomine rufo-fusco setis longis nigris obsito, pedibus nigris. (Magn. Muscæ carnariæ.) SYN. Musca hirta, _Drury, App. vol._ 2. HABITAT: Jamaica. {103}Head black. Eyes light brown. Antennæ like jointed scales, not hairy. Thorax above almost black, with a few hairs on the sides. Wings brown and opake, not transparent. Abdomen red brown, covered with very long black hairs. Legs black. REDUVIUS (CONORHINUS) VARIEGATUS. Plate XLV. fig. 5. ORDER: Hemiptera. SUBORDER: Heteroptera. SECTION: Geocorisa. FAMILY: Reduviidæ, _Leach_. GENUS. REDUVIUS, _Fabr._ Cimex, _Linn._ Subgenus: Conorhinus, _Laporte_, _Burm._ Triatoma, _Lap. olim._ REDUVIUS (CONORHINUS) VARIEGATUS. Niger; thoracis lateribus maculisque marginalibus abdominis ferrugineis, corio nigro rufo-marginato. (Long. Corp. fere 1 unc.) SYN. Cimex variegatus, _Drury, App. vol._ 2. Reduvius gigas, _Fabr. Syst. Rh._ 267. 3. _Burmeister_ II. 246. 1.? (Conorhinus G.) _Stoll._ 13. _f._ 85.? _Wolff_, 12. f. 113.? HABITAT: Antigua. Head black and small. Eyes black. Antennæ black, and shorter than the insect. Thorax black, the sides red brown and angular. Scutellum small, black, and angular. Basal portion of the hemelytra black, verged with red; the apical membrane opake and brown. Wings transparent. Abdomen black, with red spots on its sides, which are seen also beneath. Legs black, yellow at the base. The antennæ of this insect, as represented in the figure, are quite unlike those of any of the Reduviidæ, although in every other respect, and more especially in the peculiar neuration of the membranous part of the upper wings, it agrees with the Reduvius gigas of Fabricius, a species very widely dispersed, being found in South America, Sierra Leone, East Indies, as well as the Island of Mauritius. ERISTALIS CINCTUS. Plate XLV. fig. 6. ORDER: Diptera. SECTION: Athericera. FAMILY: Syrphidæ, _Leach._. GENUS. ERISTALIS, _Meigen_. Musca, _Drury, &c._ ERISTALIS CINCTUS. Ater; thorace punctis quatuor fasciâque posticâ sulphureis, abdomine castaneo fasciâ mediâ sulphureâ. (Magn. Musc. carnariæ.) SYN. Musca Cincta, _Drury, App. vol._ 2. HABITAT: Jamaica.
