122 HEMIPTERA-HETEROPTERA. 
1. Merragata hebroides. (Tab. VIII. figg. 7, ¢; 7a, antenna.) 
Merragata hebroides, Buch. White, Ann. & Mag. Nat. Hist. (4) xx. p. 114°. 
¢. Short, black, the head reddish between the eyes, the pronotum with two, posteriorly confluent, rufo- 
ferruginous spots on the posterior lobe; the elytra with a large triangular white patch on the clavus 
and a very narrow whitish streak between the nervures of the corium, the latter black at the apex, 
becoming paler towards the base, the membrane brown, with three large whitish spots; the antenne 
testaceous, with the apical joint infuscate; the legs testaceous, with the tips of the tarsi (the claws 
excepted) blackish ; the under surface with a bluish-grey pruinosity; the body, legs, and antenne 
finely pubescent. Head with a fine median groove; antenne very short, less than twice the length of 
the head, 4-jointed, 1-3 subclavate and subequal in length, 4 longer and considerably stouter than 3, 
fusiform: Pronotum rugulose, moderately constricted at the sides, longitudinally sulcate down the 
middle anteriorly, the two lobes not distinctly separated. Scutellum distinctly carinate. Legs slender. 
Venter broadly depressed along the middle. 
Length 1,8, millim. 
Hab. Mexico, Chapultepec (Bilimek, in Mus. Vind. Ces.) —Hawatian Is.? 
One specimen only of this peculiar little species has been seen; it agrees perfectly 
with the Hawaiian example (2) in the British Museum. The very short antenne, 
with joints 1-3 subequal in length and the fourth longer, stouter, and fusiform, 
separates it at once from all the other members of the family described here. It is 
probable that the species has been introduced into the Hawaiian Islands. 
2. Merragata leucosticta, n. sp. (Tab. VIII. fige. 8; 8a, antenna.) 
Short, rufo-fulvous, slightly mottled with fuscous, the venter black, except at the apex; the elytra smoky- 
brown, with a silvery-white wedge-shaped mark at the base of the clavus, the base of the corium and 
the narrow space between the nervures pale brown, the membrane with several indistinct pallid spots ; 
the antenne obscure testaceous; the rostrum, legs, cox, and trochanters flavo-testaceous; the body, 
legs, and antenne clothed with rather long, fine hairs. Head with a distinct median groove; antenne 
4-jointed, 3 and 4 very slender, 1 and 2 subequal, 3 much longer than 2, 4 much longer than 3, 
Pronotum deeply constricted at the sides, the disc without median groove, the surface with scattered 
punctures. Scutellum with indications of a median ridge, subtruncate behind. 
Length 12 millim. (2.) 
Hab. Guatemata, San Gerdnimo (Champion). 
Three examples. Shorter than Hebrus consolidus, Uhler, the pronotum much more 
strongly constricted at the sides, the silvery-white wedge-shaped mark on the clavus 
shorter, the corium without a white streak, the membrane with indistinct paler spots, 
the pubescence longer, the antenne 4-jointed. 
3. Merragata brevis, n. sp. (Tab. VIII. fig. 9.) 
Short, black or fuscous, the head fulvous in front and on cach side between the eyes, and sometimes with a 
fulvous median line; the pronotum more or less mottled with fulvous or rufo-fulvous, the anterior — 
margin constantly fulvous; the elytra with a whitish, wedge-shaped, evanescent mark at the base of 
the clavus, and a pallid streak between the nervures of the corium, the nervures themselves black at the 
apex, becoming brownish or fulvous towards the base, the membrane fuscous, usually with some paler 
spots; the antenne testaceous or rufo-testaceous, with joints 1 and 2 sometimes darker at the apex; 
the under surface black, with a greyish pruinosity, the genital segments flavous in the male; the 
antenne, rostrum, coxe, trochanters, and legs flavous; the body, legs, and antenne finely pubescent. 
Head with a distinct median groove; antenne 4-jointed, 3 and 4 very slender, 2 slightly shorter than 1,
