SPOLIA ZEYLANICA. 
A young specimen taken in January, which is apparently in the 
last pupa stage, just preceding the imago, has the dorsum of pro- 
notum rough, provided with protuberances ; the median carina of 
pronotum a little accentuated and distinctly sinuate, little arcuate 
posteriorly ; the apical process terminating acutely. The lateral 
lobes of pronotum at the inferior margins outwardly qonvex, the 
posterior angle being unarmed, having neither tubercle or spine, 
but distinctly angulate. 
I am not sure but De Saussure (1860, p. 486), included this species 
as a variety of Scelimena gavialis , where he states : “ Variat 
pronoti lateribus bispinosis vel femoribus posticis submuticis,” 
and moreover where he says : (p. 487) “ Un autre, qui est plus 
fortement peint de rouge, a une seconde petite epine aux lobes 
lateraux du prothorax, etune ou deux dents auxbords superieurs 
des cuisses anterieures ; les dents des bords inferieurs sont aussi 
plus fortes.” No red colouring whatever appears on any of the 
eight specimens I have recorded above though present in all the 
gavialis specimens. 
This species is dedicated to Mr. F. G. Logan of Chicago in token 
of his patronage of Art and Science.

Plate I., figs. 11-11 &. 
Differing from Scelimena , Serv., as follows : posterior angles of 
the lateral lobes of pronotum outwardly laminato-expanded, one 
or tridentate, rarely widely truncate. Femora compressed, superior 
and inferior carinse more or less lobate ; margins of posterior 
tibiae compressed, almost unarmed or provided with minute 
denticles on the exterior margins ; first articles of posterior tarsi 
flattened above, but the margins obtuse not laminato-produced.

Body moderately large, distinctly flattened above, prolonged 
backwards, upturned at the apex of pronotal process ; dorsum 
posteriorly rugose granulate reticulate ; facial frontal carina below 
the median ocellus obliterated. (Plate II., figs. 11-11&.) 
crocodilus , De Saussure. 
Body smaller, rougher, process abbreviated ; lateral lobes of 
pronotum trilobate ; carinse barely crenulate ; median carina ele¬ 
vated undulate, suberistate ; occiput without tubercles ; facial 
carina below the median ocellus distinct; pronotal process with 
four oblique strongly rugose elevated tubercles
