body, setaceous.

Tab. vitt.; Cuvier, R. Ani. éd. ill., Ins. Pl. 92, fig. 3; 23’” long, feet 
ringed, yellow-white, and black ; this little creature has a staggering gait, 
like some long-legged gnats},

Zelus FARR. Body linear, with very long feet. 
Mycorts Burm. Elytra entirely membranous. First joint of 
tarsi indistinct, almost entirely retracted upon the tibia.

Sp. Reduvius personatus Fasr., Cimex personatus L., DE GEER, Mém. 11. 
Pl. 15, figs. r—9; SCHELLENBERG, Cimic. Tab. vil. fig. 1; Cuv. R. Ant. 
éd. ill., Ins. Pl. 92, fig. 1; black, nine lines long; the larva covered with 
dust and flue, coated as it were, lives in houses and feeds on insects ;— 
Reduvius amenus GUERIN (Reduv. bullatus Leyd. Mus.), Guar. Zconogr., 
Ins. Pl. 56, fig. 17; 1.1'” long, abdomen vermilion red, concave above, 
cuticularly expanded with five black-blue round spots on each side; Java. 
Note.—Many sub-genera of more recent authors have been omitted, on 
which comp. BuRMEISTER (Handb. der Entomol. 1. pp. 227—247), also 
Amyot ef SERVILLE (Hist. nat. des Hénipt. pp. 321—393 ; many of the 
names barbarous, taken from the tongues of Indians, Hebrews and Chinese). 
1 There is a still smaller native species, about 1}’’ long, which has darker wings, 
and the black rings on the feet broader than the yellow-white, Ploiaria erratica, 
Gerris erraticus Kuve, Cimex culiciformis DE GEER? 11. Pl. 17, figs. t—8. The 
genus Ploiaria was established by J. A. Scopout in his Delicie Flore et Faunce Insu- 
brice (Ticini, 1786, folio), and indeed upon a wingless species from which the genus 
Emesodema was afterwards formed. This species, magnified, is several times figured in 
Scoprour’s work under the name of Ploiaria domestica, 1. Tab. XXIV. figs. 1, 2, 1. Tab. 
xx. ; the Ploioria alata in the third part, Tab. xxv. fig. v1, figured by Count 
CASTILLIONE, agrees perfectly with the species noted by me as Ploiaria erratica. 
Lesson, in his J/lustrations de Zoologic, Pl. 53, has figured, if I mistake not, the 
Ploiaria domestica of Scopout under the name of Ploiaria vagabunda.
