COPTURUS. 79 
V-shaped scutellar mark, pale metallic blue, the elytra for the rest broadly black 
at the base and brownish or cinereous thence to the tip, the under surface 
white. 
22. Copturus lamprothorax. (Tab. V. figg. 22, 23.) 
Copturus lamprothorax, Heller, Abhandl. Mus. Dresd. no. 11, p. 32°. 
Copturus lamprothoraz, var. ? latior, Heller, loc. cit. p. 33°. 
Var. The elytra variegated with fuscous or black, sometimes with an oblique interrupted band extending 
across the disc from the scutellum to near the middle of the eighth stria and then continued downwards 
to the subapical spot, the white sutural stripe dilated at the middle, and some other white scales usually 
present on the disc and in front of the humeral callus. (Fig. 23.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); GuareMaLa, San Gerdnimo, Las 
Mercedes, Duefias (Champion); Nicaracua, Chontales (Belt); Panama, Bugaba, Volcan 
de Chiriqui, Caldera, Tolé (Champion). 
Found in numbers in Chiriqui. The form with variegated elytra has been found in 
quantity, both in Chiriqui and at Toxpam, and it is connected by intermediate forms. 
The var. latior, Heller, is based upon a single discoloured example with the elytra a 
little broader than usual. The subapical dark spot is often wanting. The prothorax 
has the sides and a stripe down the middle clothed with flattened metallic-blue or 
green scales. The eyes are more approximate, and the rostrum a little longer and 
smoother, in the female than in the male. The length varies from 2-33 millim. The 
two specimens figured are from Toxpam. 
23, Copturus atrosignatus, sp.n. (Tab. V. fig. 24.) 
Elliptic, nigro-piceous, the antenne, the basal half of the rostrum, and the legs ferruginous, the elytra rufo- 
piceous, with a broad, oblique, blackish fascia below the shoulders; the vestiture close and fine: the head 
with an ochreous line around the eyes; the prothorax with three sharply-defined vitte formed by inter- 
mixed ochreous and white scales; the elytra with the base broadly, the suture, the second interstice to 
beyond the middle, and an interrupted oblique fascia towards the apex, whitish or ochreous, the rest of their 
vestiture blackish ; the scales on the under surface and legs white. Eyes large, very narrowly separated. 
Joint 2 of the funiculus elongate. Prothorax very short, densely punctate and subcarinate. Elytra deeply 
punctate-striate, the interstices rugulose and almost flat. Meso- and metasternum flattened between the 
middle coxee. Legs short, slender ; femora sharply unidentate beneath. 
Length 2,';-23, breadth 15-14 millim. 
Hab. Mexico, Toxpam (Sallé), Teapa (H. H. Smith). 
Two specimens, precisely alike. Very like C. lamprothorax, but without trace of 
metallic colour on the prothorax, the three pallid vitte sharply defined, the elytra 
with a broad, oblique fascia below the shoulder, a streak on either side of the 
suture towards the apex, and a patch at the sides in a line with it, infuscate or 
black.
