INSECTA SAUNDERS1ANA. 
the scutellum and between the dorsal spines ; straightened above—some¬ 
what widened behind—the middle of the sides ; each obtusely rounded at 
the apex; shoulders subangularly directed, but with the angle rounded ; 
obsolete striae very sinuate, punctate subgranulose, more evidently punc¬ 
tate at the base; each elytron having six spines, concolor at their base, 
then black to the apex, of which two — one lateral under the shoulder, 
the other basal, on the circumscutellar emargination, not far from the 
suture — are shorter (^— T 3 g ); the four others longer mill.): one 
latero-dorsal at the fourth, another suturo-dorsal at the middle, a third 
latero-dorsal at the two-thirds, the fourth suturo-dorsal at the posterior 
fourth, of the length. Pygidium and body beneath subgranato-punc- 
tate ; pectus partly infuscate at the sides. 
Belongs, together with the four preceding species, to my Group V. 
Genus ATTELABUS, L. (pars), Sch. (pars). 
(= Attelabus, pr. diet., Sch.) 
This subgenus of Schonherr is very numerous* and heterogenous ; 
and that acute author’s subdivisions, reposing only upon the armature of 
the femora, are now insufficient to group the species under the several 
natural types they present to the investigator. I beg to propose 
an analytical table of the types now in my hands, completing it with 
secondary characters hearing on their natural similitudes and differences. 
Sect. I. Attelabus, strict, sens. 
Caput cum rostro breviusculum, parum arcuatum, thorace haud Ion- 
gius. Rostrum capite brevius, pro ratione crassum. Caput latum, 
parallelo-quadratum, basi convexum ; fronte capite dimidio angustiore. 
Antennae crassiusculae, parum elongatae; clava oblongo-ovata, articulis 
subtransversis. Thorax subtransversus, lateribus sat rotundatus an- 
terius valde attenuato-inflexus, dorso aequaliter convexus, apice supra 
late parum emarginato—lateribus infra valde oblique—truncatus, lobis 
* More than 120 species exist in the various collections I have 
seen.
