4. Ligyrocoris oblitus, n. sp. (Tab. XIX. fig. 9.) 
Head pitchy, thickly covered with greyish pubescence; eyes and antenne pale brownish, the last with the 
basal two thirds of the first joint and the whole of the fourth joint pitchy. Pronotum pale brownish, with 
six longitudinal dark-brown fascie, two central and two near lateral margin. Scutellum pitchy, with 
three raised and paler longitudinal strie, one central and two lateral. Corium pale stramineous, with a 
small pitchy spot on disk near base, and with a broad pale brownish streak, commencing about centre of 
claval margin, and extending along the length of apical margin, where it is broadest; near apical angle 
this more or less encloses a pale stramineous spot. Membrane very pale and unicolorous whitish hyaline. 
Body beneath pitchy; sternum more or less covered with greyish pubescence. Anterior femora pitchy, 
with their apices narrowly ochraceous; intermediate and posterior tibiee ochraceous, with their apical 
halves pitchy ; tibise ochraceous. 
Long. 43-5 millim. 
Hab. Guatemata, San Gerdnimo (Champion). 
We have received two specimens of this species from Mr. Champion, which vary in 
size as stated above; they also vary in the extent of the broad brownish border to the 
apical margin of the corium, which in the larger specimen becomes obsolete towards 
the apical angle. The pale white membrane and distinct markings of the pronotum 
and corium render this an easily recognized species.

The specimen figured is the typical P. piligera, Stal, described from and contained 
in the collection of Dr. Signoret. In his description of this species Stal gives the apex 
of the first joint of the antenne as “ nigro-fuscis ;” and in his ‘ Enumeratio ’? states as a 
varietal character “articulo primo antennarum nigro.’ All the Central-American 
specimens which I have examined have the basal joint of the antennz black. 
7. Ligyrocoris infumatus, n. sp. (Tab. XIX. fig. 8.) 
Head, anterior lobe of pronotum, and scutellum black ; posterior lobe of pronotum and corium ferruginous, 
the first with four longitudinal fuscous fasciz, two central and two lateral; the corium with a spot near 
base ; a broad, irregular transverse fascia near apex, and apical angle fuscous. Membrane opaque, fuscous, 
with the veins pale at base. Antenne ochraceous, apex of third joint, and more than apical half of
