DESCRIPTIONS 
OF TWO NEW COLEOPTERA SENT BY M. DE LACERDA FROM BAHIA 
by HE». Sharp. 
G. Scorocryprus Girard () 
Tarsi omnes triarticulati. 
This character of only three jointed tarsi separates this genus 
from all the other known Siphidæ, but the combination of other 
characters it presents requires its structure to be given in full de- 
tail, and this I am fortunately able to do with some approach to 
completeness. 
The insect is rather larger than the largest Agathidium and in 
facies is intermediate between that genus and Pathyscia, having 
perhaps more the appearance of a broad Colon than of any other 
béetle I know. The head when retracted is vertical in direction and 
is closely embraced by the prothorax after the manner of Balhyscia 
and Catops, it is broad and short, has no eyes, and the antennæ are 
inserted under the sides of the front as in Agatñidium; they are 
11-jointed, and thickened externally from the 7" joint to the 11‘ 
except that the S'"is smaller than those contiguous to it. The 
labrum is small, but very exposed, strongly transverse, being very 
short, feebly emarginate in the middle, and is attached to the clypeus 
by a minute transverse membrane. The maxilla has two elongate 
lobes, each finely pubescent at the extremity, the inner is as long 
as the outer and quite membranous; the maxillary palpus is short 
and stout, and apparently three jointed; the basal joint is however 
present though extremely minute, so that this palpus is truly four 
jointed; the second joint is short and stout, but little longer than 
broad; the third is slightly more slender, twice as long as broad, 
cylindric; the terminai joint is small, almost cylindric being trun- 
cate at the apex, not so broad as the third joint, and only half its 
length. The ligula appears as an excessively delicate, very broad 
() When this description was written I was under the impression that this was 
an uncharacterised genus, but I have since discovered in the Ann. Fr. 1874, p.574 
that M. Girard has given a description of it based on a species found in nests 
of Mellipona scuteliaris at Bahia M. Gerard’s species Scolocryplus melliponæ is 
however ! think quite distinct from my S. obscurus. M. Girard describes the 
maxillary palpi as certainly only three-jointed : but the fourth joint in my 
microscopical preparation is present in the form of a very small basal joint, 
almost concealed in the body of the maxilla.
