STRONGYLIUM. 363 
or less obsolete lateral margin. As Maklin remarks, S. aulicwm is very closely allied 
to the Brazilian S. nodile. A Chontales example is figured. 
87. Strongylium decoratum. (Tab. XV. fig. 18, 2, var.) 
Strongylium decoratum, Makl. Monogr. p. 257; Act. Soc. Fenn. viii. part 1, p. 365°. 
Strongylium venustum, Mikl. in litt. 
Hab. Costa Rica (Wagner!); Panama, Chiriqui (Zrdtsch).—Bottvia '. 
A single female example before me, from Chiriqui, 14 millim. in length, differs from 
Maklin’s description of §. decoratum in having the two transverse testaceous bands of 
the elytra united at the suture, and the legs rather differently coloured (the apical third 
of the intermediate and of the posterior femora, as well as all the tibie, being testaceous, 
and the tarsi piceous); it is doubtless a variety of that insect. 
The Chiriqui specimen is figured. 
38. Strongylium panamense. (Tab. XV. fig. 19, 2.) 
Elongate, subylindrical, violaceous or bluish-violaceous, shining. Head greenish-eneous in front, violaceous 
behind, coarsely and rather closely punctured, the intraocular space and the vertex quite sparingly so, 
deeply longitudinally impressed between the eyes, the vertex in front broadly flattened and somewhat 
depressed, the antennary orbits prominent; eyes rather small, somewhat widely separated; antenne ( 9 ) 
stout, rather short, rapidly widening outwardly, joint 4 the length of but wider than 3, subtriangular, 
joints 6-10 about as broad as long, 11 ovate, entirely testaceous (in one example with the basal four joints 
greenish-eneous in tint); prothorax nearly as long as broad, subcylindrical, the sides obsoletely margined 
throughout (the margin not visible from above), gradually narrowing anteriorly, and a little rounded (in 
one example slightly sinuate before the base), the anterior angles rounded, the hind angles more or less 
rectangular, the base and apex slightly sinuate and rather feebly margined, the disc obsoletely canaliculate 
and broadly and shallowly depressed in the middle behind, the surface very sparingly and rather finely 
(but deeply) punctured; scutellum subtriangular, rather convex, smooth, violaceous ; elytra long, sub- 
parallel in their basal half, a little acuminate at the apex, striate-punctate, the punctures coarse, deep, 
and subapproximate, and slightly transverse in the basal half, thence to the apex rapidly becoming very 
much finer and shallower, and at the apex itself almost obsolete, the interstices smooth, nearly flat or but 
little raised on the basal half of the disc, convex at the apex and also (in one example) at the sides, the 
surface testaceous nearly to the middle, the apical half violaceous; beneath very bright greenish-eneous 
or cyaneous, glabrous, the coxe and trochanters with a few short hairs, almost smooth, the sides of the 
metasternum with a few widely scattered coarse impressions, the flanks of the prothorax coarsely but 
sparingly punctured ; legs stout, short, very sparingly punctured, the femora almost smooth, testaceous, 
the extreme base of the four hinder femora suffused with greenish-seneous, all the tarsi bluish-black, the 
first joint of the posterior tarsi about as long as the apical joint. 
Length 12-13 millim.; breadth 33-4 millim. ( 2.) 
Hab. Panama (coll. F. Bates), Chiriqui (Trétsch). 
Two examples, apparently both females. S. panamense is readily identified by its 
stout ferruginous antenne, obsoletely margined, subcylindrical, and comparatively 
smooth thorax, and stout legs; and also by the coloration of the elytra. A similarly- 
coloured allied undescribed species, from Southern Colombia, is contained in Mr. F. 
Bates’s collection. 
The example from Mr. F. Bates’s collection is figured.
