120 HEMIPTERA-HETEROPTERA. 
slightly infuscate ; and the pronotum is somewhat feebly constricted at the sides, the 
two lobes not being sharply separated. 
H. parvulus, Stal, from Rio Janeiro (the type of which is before me), is a very 
closely allied form ; but it has a rather more elongate basal joint to the antennae, the 
two lobes of the pronotum more distinctly separated, the wedge-shaped mark on the 
_clavus shorter, the white streak between the nervures of the corium indistinct, and 
the whitish marks on the membrane less conspicuous. . consolidus was found in 
plenty in the island of Grenada by Mr. H. H. Smith. 
5. Hebrus leviventris, n.sp. (Tab. VIII. fig. 5.) 
Rather elongate, narrow, fuscous or rufo-fuscous, the pronotum with the anterior margin and a narrow space 
down the middle indeterminately fulvous or flavous; the under surface testaceous or flavous, with the 
sides of the venter broadly blackish ; the antenne testaceous, paler at the base; the coxe, trochanters, 
and legs flavous, the knees slightly darker; the elytra smoky-brown, with a long, wedge-shaped, 
silvery-white mark at the base of the clavus and a long narrow pallid streak between the nervures of 
the corium, the latter black at the apex, the membrane with one or two obscure luteous oval spots 
along the middle, these being sometimes connected; the body, legs, and antenne finely pubescent. 
Head without distinct median groove; antenne 5-jointed, 3-5 very slender, 2 a little shorter than 1, 
3 elongate, 4 and 5 subequal in length, together slightly longer than 3. Pronotum deeply constricted 
at the sides, and with a fine transverse groove before the base, the anterior and posterior lobes sharply 
separated, the latter depressed along the middle in front; the surface with scattered punctures, the line 
of demarcation between the two lobes indicated by a few deeper impressions. Venter smooth and 
shining, the sutures between the segments almost obliterated. 
3. Second and third ventral segments depressed in the middle. 
Length 14-22 millim. 
Hab. Panama, Tolé (Champion). 
This species resembles Merragata leucosticta in colour, but it is more elongate, and 
has 5-jointed antenne; the pronotum is still more deeply constricted at the sides, 
with the two lobes more sharply separated and the posterior lobe depressed along the 
middle. The nine specimens obtained are in a bad state of preservation, one only 
having the antenne entire. 
6. Hebrus sulcatus, n. sp. (Tab. VIII. figg. 6, ¢; 6a, antenna; 64, inter- 
mediate leg, ¢.) 
Rather elongate, black, the pronotum with the disc rufous or fulvous and the anterior margin testaceous or 
flavo-testaceous ; the head reddish-brown on each side between the eyes, in one specimen entirely of that 
colour; the antenne, rostrum, legs, cox, and trochanters, and the apex of the venter, flavous or 
flavo-testaceous, the knees, tibie, and outer joints of the antenne sometimes a little darker ; the elytra 
smoky-brown, with the clavus and the narrow space between the two longitudinal nervures of the 
corium pale brown, the membrane with a narrow pallid transverse streak near the apex of the 
corium; the body, legs, and antenne clothed with short fine pubescence, the venter densely 
clothed with short pallid hairs, the entire under surface with a greyish pruinosity. Head with a very 
fine median groove; antenne about three-fourths the length of the body, 5-jointed, 3-5 very slender, 
1 elongate, more than one-half longer than 2, 3 about as long as 1, 4 and 5 equal in length, together 
fully one-half longer than 38. Pronotum strongly constricted at the sides, and with a fine transverse 
groove before the base; the posterior lobe deeply sulcate down the middle; the surface with scattered
