A common insect throughout our region, and perhaps not really distinct from 
Z. longipes (Linn.), from the Island of St. Thomas. It is very variable in colour, 
according to the predominance of the light or dark colour on the head, pronotum, and 
elytra; the two forms noticed above are not mentioned by Stal. The antenne are 
black, sometimes with one or two pale rings on the basal joint. The legs are black, 
with two conspicuous pale rings on each of the femora, which, however, are occasionally 
indistinct. The males have the third antennal joint slightly thickened to beyond the 
middle, and the terminal genital segment armed with a slender, upwardly curved spine 
at the apex. | 
The North-American Z. bilobus, Say, a specimen of which from Texas is before me, 
has a longer head and pronotum, and the femora almost entirely black *. 
_ About 100 examples of Z. rubidus have been examined, including one of Stal’s 
specimens from Cuba. 
* Prof. Uhler (Bull. U.S. Geol. & Geogr. Surv. i. p. 327) records this species from Mexico, possibly 
in error.
