the broad retractile head invisible from above; elytra finely mar- 
gined. Coxal lines prominent, that of the metasternum extending 
round the coxae to the episternal suture, that of the first ventral 
segment running in front of the apical margin of the latter to its 
outer limit. Tibiae broad, the anterior pair deeply sulcate. for the 
reception of the tarsus. 
Length 23, breadth 1,9, mm. 
Hab. Panama, Bugaba (Champion). 
One specimen, found in our collection mixed with 
Scymnus panamensis, to an abraded unset example of 
which it bears a certain amount of resemblance. The 
aeneous elytra, with rufous apex, and the rufous head and 
thorax, are characteristic of the present species. 
*Cryptognatha violacea, n. sp. 
Hemispherical, very convex, shining, glabrous ; cupreo-violaceous, 
the head above (in part or entirely) and beneath, the last four 
ventral segments, and the legs ferruginous, the rest of the under 
surface black. Head and thorax closely, minutely, the elytra more 
sparsely and distinctly, punctate, the punctures on the elytra 
becoming coarser towards the outer margin; thorax very broad; 
elytra finely margined. Beneath rather closely punctate. Coxal 
lines prominent, that of the metasternum extending round the 
coxae, that of the first ventral segment running just in front of 
the apical margin of the segment to its outer limit. Tibiae broad, 
the anterior pair deeply sulcate for the reception of the tarsus. 
Length 2,1,-24, breadth 2 mm. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 
Two specimens, found placed in our collection under 
C. flaviceps, Crotch, but not agreeing with the author’s 
description, nor with the other Central American examples 
identified by Gorham as that species. These latter have 
more broadly margined elytra, the upper surface black, etc. 
*Cryptognatha fenestrata, n. sp. 
Hemispherical, very convex, shining, glabrous; black, the elytra 
each with a large rufous patch on the middle of the disc, the coxae 
and legs testaceous. Thorax closely, minutely, the elytra more 
sparsely and much more distinctly, punctulate. Coxal line of 
the first ventral segment extending outwards in a feeble curve to 
within some little distance of the outer margin of the segment. 
Tibiae broad, the anterior pair deeply sulcate, 
Length 13 mm,
