STATIRA. Li 
almost smooth, the eyes quite small and widely separated in both sexes, the space behind them rather 
broad ; antenne reddish, slender towards the base, thickening outwardly—the apical joint in the male 
almost the length of joints 6-10, in the female about as long as 8-10, united; prothorax longer than 
broad, the sides feebly margined towards the base, slightly arcuate anteriorly, and only moderately 
constricted behind, the hind angles acute, the basal margin moderately raised, and at the sides shallowly 
grooved within, the surface very shallowly, sparsely, and minutely punctured (the punctures sometimes 
more distinct) and without any trace of fovew in either sex; elytra with long and rather shallow intra- 
humeral depression, moderately long, widening gradually from the base to beyond the middle, rather 
deeply striate throughout, the punctures of the striz fine and close, the interstices feebly convex but 
becoming flatter towards the base, the third and fifth each with from six to eight (scattered between the 
base and apex), the seventh sometimes with one (at the shoulder), and the ninth with about six (chiefly 
towards the apex), moderately coarse setiferous punctures, the apices obtuse ; beneath brownish-piceous, 
shining ; legs rather slender, piceo-testaceous, the tarsi testaceous. 
Length 63-82 millim.; breadth (at shoulders) 13-23 millim. (¢ 9.) 
Hab. Guatemata, Cubilguitz in Vera Paz (Champion) ; Nicaracua, Chontales 
(Belt). 
Var. The head and prothorax usually lighter in colour, the base and apex of the latter more or less reddish- 
testaceous ; the elytra testaceous, with the sides for about two-thirds of their length, the base (narrowly), 
and a transverse band about the middle (connected with the lateral stripe and widening a little at the 
suture and laterally) more or less greenish-eeneous, and a triangular common sutural patch (sometimes 
connected with the lateral stripe) midway between the transverse band and the apex piceo-sneous ; legs 
testaceous, the apices of the posterior femora sometimes darker. (3 2.) 
Hab. GuatEMa.a, Cubilguitz in Vera Paz (Champion). 
The unicolorous form is taken as the type, of which we have one male from Nicaragua 
and two females from Guatemala; of the variety we have six examples. 
The typical form of S. inconstans closely resembles S. foveicollis; it differs as 
follows :—The head and thorax are without eneous tinge; the latter has no trace of 
lateral fossa in either sex, and is only moderately constricted behind; the eyes are 
smaller; and the elytra are more deeply striate, and have from six to eight rather 
coarse setiferous impressions on both the third and the fifth interstices. 
From 8. vélis in all its varieties the more or less greenish-zneous elytra and invariably 
reddish-testaceous antenne distinguish it at once. 
Both forms were collected together at Cubilguitz. 
19. Statira viridicollis. (Tab. I. fig. 15, 3.) 
Very elongate, rather depressed, greenish-eneous, the elytra of a more brassy tint, shining. Head sparsely 
and finely punctured, the eyes large ; antenne long and rather. stout, fusco-ferruginous, the basal joint 
darker, the apical joint in the male as long as joints 6-10 united, these latter rather elongate, 10 very 
little shorter than 9; prothorax about as long as broad, a little flattened on the disc, the sides narrowly 
margined towards the base, moderately rounded anteriorly, strongly constricted behind, and with traces 
of an irregular transverse depression about the middle, the hind angles acute and very prominent, the 
basal margin moderately raised and shallowly (except in the middle) grooved within, the surface irregularly, 
rather closely, and not very finely punctured, a narrow longitudinal space on the middle of the disc almost 
impunctate ; elytra with very shallow intrahumeral depression, very long, a little flattened on the disc, 
subparallel to about the middle, finely and deeply punctate-striate, the punctures closely placed, but more 
scattered towards the apex, the interstices feebly convex, the third with four (near the apex), the fifth
