into conical lobes, rounded apically, with a row of small, round 
tubercles. Anterior border with two (1+1) short ridges placed behind 
collar, separated from each other by a thin, median sulcus. Behind 
calli median sulcus becomes wider and deeper. Hind border straight 
laterally, deeply incised in the middle. Disc rugose, partially deeply 
punctured. 
Mesonotum fused with metanotum and terga I and II. Median 
portion of this plate triangularly raised, with apex inserted into 
incisure of hind border of pronotum. Mesometanotal plate laterally 
depressed between mesonotum and metanotum, and raised on metano- 
tum. Disc densely, deeply punctured, particularly in the middle. 
Lateral borders of mesonotum produced into two (1+1) lobes similar 
to those of pronotum; lateral borders of metanotum convex, rounded. 
Abdomen as long as width across segment V (07, 74:75; 9, 90:91). 
Terga I and II completely fused with metanotum, but separated from 
central dorsal plate by a deep sulcus. Central dorsal plate consists of 
terga III to VI completely fused together, raised in area of dorsal 
scent gland scars, with carinae dividing disc into a few irregular 
portions; these portions deeply punctured along carinae; tergum IIIT 
is punctured on the whole surface. Connexivum wide; segments IT and 
III fused; exterior border of connexivum II roundly produced anteri- 
orly; PE angles III to V angularly produced with blunt tip; PE VI 
and PE VII produced as conical lobes with rounded tip. Tergum VII 
raised posteromedially. Paratergites short, reaching middle of hypopy- 
gium; latter caudal in position, deeply inserted; disc of hypopygium 
with a short median ridge. In female, tergum VII conically raised 
posteromedially; paratergites conically produced as far as segment 
IX; latter truncated posteriorly. Spiracles IJ ventral; III sublateral; 
IV to VIII lateral and visible from above. 
Cotor.—Dark brown, shiny, concealed by gray incrustation. 
MerasuREMENTs.—Total length: &@, 5.64; 9, 6.84 mm; width of 
pronotum: 6, 1.96; 2, 2.20 mm; abdomen width: 0, 3.0; 9, 3.64 mm. 
Hototypr.— Male, Dominica, W.1I., VI.1963, J. Maldonado 
(USNM type 69612), from Drake collection. 
ALLoTYPE.—Female, collected with holotype ‘in copula’; in the 
same collection. 
Remarks.—Lretmocoris dominicus is related to EH. gigas Usinger 
and Matsuda from which it differs by much smaller tubercles on the 
neck; by absence of thin projections on the foreborder of pronotum; 
by conical lobes on lateral borders of pronotum and mesonotum; and 
by progressively produced PE angles of connexiva.
