350 HETEROMERA. 
and tibiee in some examples more or less reddish, the tarsi cyaneous ; the first joint of the posterior tarsi 
very short, not half the length of the apical joint. 
Length 144-15 millim.; breadth 5 millim. ( 2.) 
Hab. Nicaracvua, Chontales (Belt); Panama, Volcan de Chiriqui 3000 feet (Cham- 
pton), Chiriqui (bbe). 
Four female examples. _S. tinctipes in general facies and size approaches S. exaratum ; 
but is at once separated by the short legs and antenne, more transverse eyes, much 
larger thorax, the flat interstices and the somewhat pointed apices of the elytra, &c. 
The*example from Nicaragua differs from the others in having the head and thorax 
more finely and more closely punctured, the disc of the latter only very shallowly 
impressed before the base; in other respects it agrees exactly. An allied species from 
Brazil is contained in Mr. F. Bates’s collection. 
A Chiriqui specimen is figured. 
Elytra rather broad, somewhat depressed, irregularly foveolate-punctate to the middle 
and thence to the apex sulcate, transversely impressed on the disc before and behind 
the middle; eyes small ; upper surface bright greenish-bronze. 
16. Strongylium exaratum. (Tab. XV. fig. 7, 2.) 
Elongate, depressed, bright greenish-eeneous, sometimes with a slight cupreous tint. Head coarsely, very 
irregularly, and not very closely punctured, shallowly longitudinally impressed between the eyes, the 
latter rather small and widely separated in both sexes ; antenne long, in the male reaching to about the 
first fourth of the elytra, slender, the joints uarrow and subparallel, 3 and 4 long, subequal, the penulti- 
mate joint fully twice as long as broad, the apical joint much longer than the tenth, joints 1-5 cyaneous, 
the rest dull black; prothorax rather small, strongly transverse, feebly convex, the sides immarginate, 
somewhat rounded, and narrowing very little more in front than behind, the apex nearly straight, the 
base slightly sinuate and strongly margined, the hind angles subrectangular, the anterior angles rounded, 
the disc very distinctly canaliculate (deeply so towards the apex), and usually with a shallow transverse 
impression on each side above the deep basal foves, the surface coarsely, sparingly, and very irregularly 
punctured ; scutellum triangular, almost smooth; elytra long, rather broad, depressed, subparallel to 
beyond the middle, the disc shallowly transversely impressed a little before and again a little behind the 
middle, the scutellar region also a little depressed, striate-punctate, the stris coarsely punctured at the 
extreme base, the third to the eighth thence to beyond the middle with coarse irregular excavations (the 
first and second for the same distance with scattered fine oblong impressions) and much interrupted, and 
beyond this to the apex all with very fine and shallow oblong punctures, the interstices smooth, irregularly 
raised towards the sides from a little below the base to the middle and here and there obliquely confluent, 
and thence to the apex convex, at the apex itself strongly subangularly raised; beneath more shining, 
greenish-zneous much tinted with golden, very sparingly and minutely punctured, the sides of the meta- 
sternum (sparingly) and the flanks of the prothorax coarsely so; legs long, rather slender, the femora 
sparingly and shallowly, the tibize closely and roughly, punctured, greenish-zneous with a slight cyaneous 
tint, the tarsi bluish-black ; the first joint of the posterior tarsi long, as long as the apical joint; anterior 
and intermediate tibie very slightly curved in the male (straight in the female), the anterior tarsi also 
distinctly dilated and the fifth ventral segment shallowly excavate in the middle behind in this sex. 
Length 13-16 millim.; breadth 4-53 millim. (¢ 9.) 
Hab. Guatemata, Purula 4000 feet, Panima in Vera Paz (Champion). 
Numerous examples, all females but two. This species somewhat resembles
