INSECTA SAUNDERSIANA. 
Rostrum much shorter than the head, angularly inerassate to the 
apex; angularly convex, with two elevated lines diverging from the 
antennae to the apex; punctate; two unequal longitudinal strigae 
diverging towards the forehead, with a thick elevation between these; 
forehead rather broad, impressed behind ; head longer than broad, 
unequally strigose-punctate lengthwise anteriorly, having a deep canali- 
culiforra fovea posteriorly, where it is slightly punctate, convex and 
smooth. Thorax with two large ante-basal mammiferous approximate 
tubercles and another smaller on each side of the middle; these four 
tubercles glossy; besides these, two anterior, ovate, smaller, much less 
glossy, strigose, are perceivable. Each elytron bears three rows of 
tubercles, the innermost composed of four, the median of three, the 
external of two. Anterior tibice of the male longer and more slender 
than in the female, more arcuate, the interior spine of their apex 
is shorter and broader, the exterior is more elongate and incurvate. 
Genus EUSCELUS, Germ., Sch. 
This subgenus of Schonherr is now rather numerous: I have seen 
nearly fifty species. They may be distributed in the following types:— 
I. Antennae breves, capite cum vostro breviores, crassae; articulis 5-8 
transversim rotundatis, clava oblongo-ovata, obtuse acuta. 
Sculellum elevatum, transversim subquadratum. Elytra 
elongata, postice callosa, apice retusa, punctato-striata, emar- 
ginatuva scutellari obtuse transversim quadrata. Pedes antici 
longissimi : femoribus $ elytris multo longioribus, $ paulo 
brevioribus. ( Euscelus , pr, d.) Typus : Eusc. longimanus, F. 
Congen. : Eusc. brachiatus , Sch., &c. 
II. Antennae parum crassae, sat elongatae, capite cum rostro lon- 
giores, articulis 5-8 aut longioribus aut non brevioribus quam 
latis ; clava evidentius 4-articulata,* aut oblonga aut elongata. 
* I say on purpose “ evidentius 4-articulata,” because I am con¬ 
vinced that in Euscelus (even in Attelabus ?) the clava is 4-articulate:
