of the elytra partly infuscate. According to Guérin the pale of C. reticulata (tof ¢) 
are obliquely obovate. 
7. Corixa sexlineata, n. sp. (Tab. XXII. figg. 22, 22a, ¢.) 
¢. Moderately elongate, rather slender, smooth, shining; pale testaceous, the eyes black; the pronotum 
nigro-fuscous, with six narrow transverse yellow lines (these being narrower than the five dark 
interspaces) ; the elytra nigro-fuscous, with short, narrow, undulate, transverse pale lines, these becoming 
quite straight on the basal portion of the clavus, the marginal area with a spot towards the apex and the 
. costa blackish ; the dorsal surface of the abdomen with two black spots in the middle; the apices of 
the intermediate tarsi slightly infuscate ; the hind tarsi with long fuscous hairs. Head with two rows 
of punctures on the vertex and some other punctures close to the eyes, and with a projecting point in the 
centre at the base, the interocular space at the base much narrower than one of the eyes; the frontal 
depression very large, oval. Pronotum not carinate. Anterior tibia strongly produced at the apex ; 
pale broad and somewhat piriform, rather blunt at the tip. Intermediate tibie nearly one-half longer 
than the tarsi, the latter not quite so long as the claws. Ventral segments asymmetric on the right 
side. Strigil on the left side, transverse, with three rows of teeth. 
Length 4 millim.

One specimen. Differs from the two preceding species, and also from the other 
small American forms already alluded to, in having fewer transverse lines on the 
pronotum. The eyes at the base, as seen from above, are one and a half times the 
width of the interocular space. The pale markings on the elytra are narrower than in 
C. marve or C. parvula.

do. Moderately elongate, smooth and shining, flavo-testaceous, the eyes black; the pronotum with from 7-9 
very slender transverse black lines, and the large black spot on the disc of the mesonotum and a short 
oblique black streak on either side of it posteriorly showing through ; the elytra with the clavus, except 
for a broad space at the base (the part covering the motanotum), corium, and membrane closely marked 
with short, undulate, irregular, transverse black lincs, the marginal area pale, with a black mark at the 
apex and a faint transverse dark streak a little beyond the middle; the abdomen, and sometimes the 
meso- and metanotnum also, partly black ; the legs entirely pale. Head with a short median carina at 
the base, and with two interrupted series of punctures on the vertex and some other punctures near the 
eyes ; the frontal depression very large, almost extending to the inner margin of the eyes, oval, moderately 
deep. Pronotum with a conspicuous median carina in front. Elytra very minutely punctulate, deeply 
sinuate at the sides before the middle of the marginal area. Anterior tibie stout; pale broad, spoon- 
shaped, somewhat pointed at the tip, with a row of very long hairs on their inner edge. Intermediate 
tibie nearly one-half longer than the tarsi, the tarsi a little shorter than the claws. Ventral segments 
of the abdomen asymmetric on the left side. Strigil on the right side, oval, much Jonger than broad, with 
six rows of teeth. Fifth dorsal segment: with a fringe of very long bristly hairs at the right outer angle, 
these projecting over the anterior part of the strigil. 
@. Broader and paler, the discal spot of the mesonotum smaller or absent; the head convex in front; the
