Mr. A. Murray on Coleoptera from Old Calabar. 93 
I have come to the conclusion that the allotment of only three 
ridges to this species is a mistake on the part of Mr. Thomson. 
In all the allied Lycide the ridges are usually the same in 
number; and it seems by no means probable that in one sec- 
tion there should be two different species, so nearly allied 
to each other, yet having different numbers of ridges on 
the elytra. In many, however, and in particular in this spe- 
cies, the four ridges are not always observable at the base, 
the fourth being sometimes concealed or, rather, occupied 
by the shoulder; but nearer the apex they are all four always 
very visible. 
Dascyllide. 
PTILODACTYLA, Latr. 
Ptilodactyla punctatostriata. 
Nitida, castanea, elytris dilutioribus; thorace distincte et 
crebre leviter punctato; elytris punctato-striatis, interstitiis 
levissime sparsim punctatis. 
Long. 24 lin., lat. 2 lin. 
Shining, chestnut-coloured, the elytra a little paler than the 
thorax. Head finely punctate and slightly pubescent. Thorax 
distinctly and (under a lens) rather deeply and thickly 
punctate, most closely on the sides and angles, not so closely 
but with larger punctures on the disk. Scutellum _heart- 
shaped, with two raised lobes at the base, finely punctate. 
Elytra punctate striate, base and shoulders less so, the inter- 
stices finely punctate ; the striz disposed obliquely, except the 
sutural stria, which is straight; the shoulder separates two 
strie, which unite about halfway down, those on each side of 
these again unite concentrically below them; the stria next to 
the sutural one is short, and fills a space left at the base by 
the oblique direction of the others. 
This is another instance of the occurrence at Old Calabar 
of American forms (most nearly related to Brazilian types). 
Ptilodactyla is strictly an American genus, and has not hitherto 
been recorded as met with in the Old World.

(Fig. 5; and details, figs. 6-11.) 
Mentum subtriangulare, apice truncato. Ligula quadrilobata, 
lobis duobus utroque latere conicis magnis ciliatis (fig. 6). 
Maxille lobo exteriore in duos lobos diviso rectos tenues et 
ciliatos ; lobo interno lato, apice truncato, forsan semifisso 
* From kérra, I cut, and xépas, a horn, in allusion to the truncate termi- 
nation of the last article of the antenne.
