PHRISSOLAUS. 
Lepturgi affinis, at differt antennis et elytris rigide setosis, feminaque ovipositore elongato subtubulari munita. 
Corpus parvum, convexum, naviculare. Caput antice latum, breve; oculi maximi. Antenne corpore 
duplo longiores, subtus sat dense rigide setosx, articulo tertio quam scapus paullo longiore. Thorax 
paullo transversus, antice modice subrecte angustatus, spina laterali valida, acutissima, acuta, extante, 
prope angulum posticum sita, pone spinam lateribus sinuatim modice constrictis, basi supra depressa. 
Elytra convexa, apicem versus attenuata, apice valde oblique sinuatim truncata, angulo exteriore longe - 
producto, supra setis rigidis lineatim digestis. Pro- et mesosterna ut in Leiopo angustata. Femora haud 
elongata, clavata; tarsi breves, postici articulo primo quam duo sequentes longiore. 
g. Segmentum terminale dorsale attenuatum, acutum ; ventrale elongatum, obtusum. 
©. Segmentum terminale mox a basi modice angustatum, elongatum, subtubulare, laminis dorsali et ventrali 
apice rotundatis. 
This genus bears a similar relation to Lepturges as Sporetus to Nyssodrys, being 
distinguished from its allied genus by the bristly clothing of antenne and elytra. 
But it has a further distinctive character, peculiar to itself, in the terminal segment of 
the abdomen in the female being lengthened to form a sheath to the ovipositor, in a 
way not seen in any of the allied genera. Without projecting much beyond the tips of 
the elytra, the segment is longer than all the remaining segments taken together, and 
is nearly of equal width from the base to the apex, the latter being entire and rounded 
in both the dorsal and ventral valves. 
J should have referred the species described below to the North-American genus 
Graphisurus (Kirby), the characters of which have been recently established in a satis- 
factory manner by Dr. Horn (Trans. Amer. Ent. Soc. viii. p. 129), had it not been for — 
the difference in the ventral plate of the ovipositor, which, in Graphisurus, is described 
as emarginated. 
1. Phrissolaus inspersus. 
Cano-griseus, antennis, thoracis vittis duabus (interdum indistinctis) elytrorumque guttulis numerosis (seriatim

SYMPAGUS.

infra haud angustata; oculi parvi, haud convexi. Antenne fere nude, scapo elongato versus apicem 
clavato. Thorax sat ante marginem posteriorem angulatus nec spinosus, ante angulum multo, pone
