$36" HETEROMERA. 
basal joints stout, and the following ones gradually tapering to the apex ; joints 1-3 are 
rather short, subequal, 4-6 each nearly one half longer than 3, 11 very slender. The 
underside is black ; the coxe and trochanters, and usually the base of the femora also, 
are testaceous. The elytra are a little widened posteriorly, and this character gives the 
insect a Lyciform appearance. The fifth ventral segment is divided down the middle 
in the male. Z. nigromaculata much resembles some species of the Longicorn genus 
Pteroplatus.

We have not received an example of the form of this insect described by Dugeés'. 
The following are, I have no doubt, colour-varieties of the same species :— 
Var. a. The head with the sides and a median vitta extending forwards as far as the middle of the eyes (this 
marking obsolete in one example), and a rather broad line along the prothorax and scutellum in con- 
tinuation of this, piceous or black ; the elytra entirely reddish-yellow ; the underside and legs black. 
Var. B. The head, prothorax, and scutellum with a median vitta, asin a. The elytra black, with the sides to 
about one third from the base rather broadly reddish-yellow ; or reddish-yellow, with the apical half or 
more, and two or three stripes extending from it forwards, black—the stripe nearest the suture extending 
to the base, widened anteriorly, and there confluent with the one on the opposite elytron. The underside 
and legs black. 
The following are the chief characters mentioned by Dugés ! :-—“ 'Tawny-yellow, with 
the antenne, the apices of the tibie, the tarsi, and sometimes the sides of the abdomen 
black; the head triangular; the antenne setaceous—joints 1-3 triangular and sub- 
equal, 4 longer than 3, 5-10 equal in length but decreasing in thickness, 11 sub- 
cylindrical; the thorax long, campanulate, with a well-marked dorsal groove, the 
surface very densely punctured ; the elytra separately rounded at the apex, pubescent.” 
‘The insect has a very Lyciform appearance. The elytral pubescence is dense, and of 
a brick-red colour, the surface beneath being yellowish. The antenne are strongly 
setaceous, the joints from the fifth rapidly diminishing in thickness. ‘Lhe entire upper 
surface is very densely and finely punctured. 
Both the varietal forms were obtained at Cordova. 
10. Zonitis megalops. (ab. XVII. fig. 26, ¢.) 
Elongate, parallel, opaque, finely pubescent; brownish-testaceous, the head in front, an ill-defined median vitta 
on the prothorax, and a similar mark on the scutellum, reddish-brown, the eyes black, the tips of the 
mandibles and the palpi piceous, the base of the elytra slightly infuscate (perhaps owing to discoloration) ; 
the antenne piceous, with the base of each joint very narrowly testaceous; beneath pitchy-brown ; the 
legs testaceous, with the middle of the femora, the apices of the tibia, and the tarsal joints (except at the 
base) stained with fuscous. Head as wide as the prothorax, rounded at the sides behind, moderately 
prolonged anteriorly, densely and finely punctured, more coarsely so in front; the labrum about as broad
