marginatis ; pedibus modicis, rufo-testaceis, femoribus simplicibus, tibiis ad apices parum dilatatis, externe

Body perfectly hemispheric, furnished with very short golden hairs at wide intervals, rufous or rufo-castaneous, 
slightly shining. Head very large and broad, minutely and rather closely punctured, with the interstices 
alutaceous ; mouth not prominent; eyes wanting; antennw moderate, rather slender, with the club but 
slightly incrassated, placed below the frontal plate immediately in front of the eyes. Thoraa small 
and short, broader but not longer than the head, widest at the base, minutely and rather closely punc- 
tured, with the interstices strongly alutaceous ; sides rounded and slightly margined; basal margin faintly 
arcuate ; all the angles obtuse. Scutellum short and broad, triangular, alutaceous. Elytra semicircular, 
not longer or broader than the head and thorax, widest at the shoulders, transversely and deeply strigose 
orasperated ; sides rounded and margined. Legs moderate, rufo-testaceous; femora simple; tibie slightly 
dilated towards the apex, and there armed on the outside or on both sides with a short spur; posterior 
tibie slightly recurved, and finely spinose on the inner side, all the tarsi 3-jointed; with the basal two 
joints furnished on the underside with flat coriaceous processes. Underparts rufo-testaceous, more or less 
alutaceous, furnished. with very short golden hairs at wide intervals ; femora longitudinally strigose. 
Hab. Guatemata, Cerro Zunil (Champion). 
Two specimens of this curious insect were found by Mr. Champion in a hollow tree, 
in the nest of a Honey-Bee belonging to the genus Melipona. 
The present species is certainly distinct from S. melipone, Girard. It is only half 
as large, hemispheric in form, and without any trace of longitudinal strize on the elytra. 
The elytra are deeply and strigosely asperate, after the manner of Cyrtusa; and in 
colour rufo-castaneous, instead of “ pitchy or blue-black ” as in S. melipone. 
CREAGROPHORUS, gen. nov.* 
Body subhemispheric. Head large and broad; clypeus distinctly marked, corneous; antennal grooves very 
distinct. Thorax very short, transverse, deeply excavated in front. Scutellum triangular. Elyira 
large, entire, with the epipleural fold very broad. Wings ample. Antenne 11-jointed, 1 and 2 large, 
cylindrical, 3 nearly as long as 2, slender, 4-6 short, nearly equal, 7 very large, 8 very small, patelliform, 
9, 10, 11 each larger than 7, 11 obtusely conic; club much incrassated. Palpi: macillary moderate, 
rather slender ; 4-jointed, 1 very small, 2 longer and broader than 1,3 and 4 more than twice as long 
as 2, nearly equal, 4 slightly incurved, obtusely pointed; labial very large, strongly recurved, and 
furnished at the apex with a very strong and very long seta or setiform process, exceeding in length the 
entire palpus; 3-jointed, 1 short, pyriform, and recurved, 2 longer than 1, incrassated anteriorly, 
3 longer and broader than 1 and 2 united, strongly incurved, and obtusely pointed. Labrum very small, 
coriaceous, strongly rounded on each side, and deeply hollowed in the middle. Mandibles short and very 
broad, very convex at the back, and deeply emarginate at the base, acutely pointed and armed below the 
point with a very large and very sharp tooth. Mawillw large, bilobed: exterior lobe small and slender, 
with incurved sete at the apex ; inner lobe very large, fringed for its whole length on the inner side with 
long incurved sete ; stipes moderate. Mentum short, transverse, widest at the base, the sides straight and 
strengthened with broad costa; suwbmentum similar, but inverse in shape, and strongly constricted near 
the base. Labium short, widest anteriorly, extending between the palpi in a long, slender process with the 
apex truncate ; sides of the labium recurved and acutely pointed below the palpi. Lingua short, scarcely 
visible beyond the labium. Prosternwm very short, elevated between the coxe into a very thin carina ;
