164 SCAPHIDIIDZ. 
rather broader but scarcely longer than the head and thorax, widest near the shoulders, marked with 
minute punctures placed in strie, the interstices alutaceous ; humeral row of punctures obsolete; yellow, 
with two small black spots on the shoulder and one large oval black spot on the disc of each elytron ; 
sides margined and very slightly rounded, the margin black; extremities broad and rounded. Abdomen 
conic, flavescent, with the base of the apical segment dusky. Legs moderate, the femora and tarsi rufous, 
the tibie dusky. Underparts entirely red. 
Hab. Mexico, Cordova (Sallé). 
S. lineaticolle differs from S. variabile in the absence of the basal row of punctures 
from the thorax, and in the shape and disposition of the markings on its disc—these 
markings being in the form of lines and not round spots; two are placed on the median 
line, a position never occupied on the thorax in S. variabile. The present insect may, 
however, be an extreme variety of that species.

apicibus late nigris, stria suturali profunda et profunde punctata, punctorum ordine humerali valde con-

Long. corp. 5 millim.; lat. 3 millim. 
Body broad, ovate, rather depressed, moderately shining ; thorax rufo-piceous; elytra red, with a large, trans- 
verse, reniform, black spot on each near the middle, and the extremities broadly black. Head rather 
small, rufescent ; eyes not prominent; antenne rather short, rufous, with the club black. Thoraw large 
and broad, widest at the base, rufo-piceous, alutaceous, marked with remote indistinct punctures; basal 
row of punctures obsolete ; basal margin produced towards the scutellum, with the angles acute. Scutellum 
very small, triangular, black. Hlytra broad, depressed, rather broader but scarcely longer than the head 
and thorax, widest near the shoulders, indistinctly punctured, with the interstices smooth; red, witha large, 
transverse, reniform, black spot on each near the middle, and their extremities broadly black; sutural stria 
deep and deeply punctured ; humeral row of punctures very distinct ; sides faintly margined; extremities 
broad, rounded, and more deeply punctured. Abdomen much exposed, rufo-piceous. Legs long, nigro- 
piceous. Underparts black. 
Hab. Panama, Caldera in Chiriqui (Champion). 
Differs from S. variabile in its larger size, much broader form, shorter antenne, and 
nigrescent legs, and also in colour and sculpture. 
This species in some respects agrees with Reitter’s description of 8. fascipenne, from 
Brazil (Verh. Ver. Briinn, xviii. p. 38), but differs from it in the absence of the basal 
row of punctures from the thorax. The single specimen found by Mr. Champion 
appears to be obscurely marked with spots on the thorax.
