ZURUS. 
Zurus, Heller, Abhandl. Mus. Dresd. no. 11, pp. 3, 5 (1895); Tijdschr. voor Ent. xl. p. 199 (1897). 
This genus includes various Tropical-American forms, four occurring within our 
limits. They are easily recognizable by the angularly produced basal lobe of the 
prothorax, which fills the scutellar cavity (the scutellum itself not being visible), the 
deeply excavate horseshoe-shaped mesosternum, and the equally unidentate femora. 
The Central-American species may be separated thus :— 
Joint 2 of the funiculus much longer than 1. 
Prothorax with a red collar in front, the posterior lobe ochreo-trivittate ; 
elytra without definite markings See 
Prothorax red, with a transverse black patch on the disc; elytra with 
large red patches . 2. 2... we ee ee ee eee COCCInatUS, SP. TL

1. Zurus sanguinicollis, sp.n. (Tab. VI. figg. 5, 5a.) 
Elliptic, black, the antennz ferruginous, the vestiture rather coarse: the head with an ochreous line around 
the eyes above, the sides vermilion-red; the prothorax with three vitte on the posterior half of the disc 
and three spots at the sides (the outer two scarcely visible from above) pale ochreous, the anterior portion 
vermilion-red ; the elytra rather sparsely clothed with small narrow ochreous and white scales, which are 
condensed into short streaks and spots towards the base, the seriate punctures each bearing a white 
scale; the under surface clothed in part with coarse white scales, the ventral segments 1 and 2 with two 
bare black stripes, which extend outwards along the apical portion of each segment. Eyes almost 
contiguous in front. Joint 2 of the funiculus elongate, much longer than 1. Prothorax transverse, 
rounded at the sides, narrowed and strongly constricted in front; coarsely, densely punctate, and 
subcarinate. lytra cordate, broadly flattened on the disc, the outer apical portion depressed and 
obliquely truncate, the apex itself sinuato-truncate, the humeri swollen, bare, and shining, the base 
sharply margined; punctate-striate, the interstices densely rugose. Femora sharply unidentate, the 
posterior pair acutely produced at the apex. 
Length 53, breadth 34, millim. 
Hab. Wonvuras (Mus. Brit.). 
One specimen, received at the British Museum in 1545. This insect has the 
prothorax coloured very much as in Copturus tricolor, from which it is easily separable 
by the more rugose sculpture, the shorter, cordate elytra, the non-visible scutellum, &c. 
2. Gurus coccinatus, sp. n. (Tab. VI. figg. 6, 6a.) 
Broad, rhomboidal, shining, black, the antenne ferruginous ; the sides of the head, the prothorax (a transverse 
patch on the disc behind and the basal margin excepted), a large, common, subtriangular patch on the 
basal half of the suture of the elytra (extending outwards to the third row of punctures), a curved mark 
at the apex, and a large spot on the outer part of the disc at about the middle, vermilion-red, the 
prothorax with a row of narrow pale brownish scales along the basal margin; the base of the rostrum, 
the anterior portion of the prosternum, the mesothoracic epimera, the metasternum, the ventral segments
