1388 Mr. Walter F. H. Blandford on the 
away from suture so as to form an angle with its fellow above the 
terminal impression, and then sinuate at sides; external angles 
produced in a curve downwards and backwards, their outer border 
serrate ; impressed surface very shining, elevated at suture, and 
concave above external angles, its outline an incomplete oval, 
emarginate below, the emargination deeper than wide, but shorter 
than the terminal surface measured along the suture, its sides 
nearly straight, not toothed, and apex rounded. Last abdominal 
segment concave. 
This species is one of the Platypi cupulati, and can 
be separated from all described species except the 
following, by the fact that in them the suture is notched 
or narrowly emarginate above the terminal impression, 
and the svtural border forms a sharp and distinct angle 
with the upper margin of the impression, whereas in these 
species the sutural margin is gradually rounded into that 
ef the impression without trace of any angle, so as to 
form a wide emargination. It can also be separated from 
most by the absence of any trace of a tooth on the lower 
apical emargination. 
Platypus hamatus, sp. n. 
Fem. Elongata, ferrugineo - testacea, elytris apice paullo 
obscurioribus ; fronte impressa, in medio foveolata ; prothorace 
oblongo, punctis magnis et parvis irregulariter notato, parte antica 
sulci utrinque punctis paucis circumdata; elytris lineato- 
punctatis, interstitiis planis, parcissime punctatis, apice excavato- 
impresso, lunato, inferne late emarginato, angulis extremis longe 
productis, margine supra depressionem intus ad suturam curvato, 
convexo. Long. 4°2 mm 
Two examples at Yuyama and Miyanoshita. 
Elongate, reddish testaceous, with elytra darker at apex. Head 
with front subconcave, foveolate in middle, finely reticulate, and 
rather coarsely punctate above, vertex strongly punctured with 
a fine median elevated infuscate line. Prothorax more elongate 
than in P. calamus, sulcus deeper at extremities than in middle, 
with about a dozen punctures on either side of anterior extremity, 
remainder of surface with irregular punctures of two sizes, a 
slight impression on either side, about middle more closely 
punctured, anterior and posterior borders finely reticulate. Elytra 
with sculpture of surface similar to that of P. calamus, termi- 
nating in a vertical impressed surface, which is lunate and widely
