ZAMMARA, 3 
This truly Neotropical genus has not been recorded north of Mexico; nor does it 
probably extend in the opposite direction beyond the South-Brazilian subregion ; it 
appears to be also absent from the Antillean fauna. About seven species of this genus 
are known, two of which are found in Central America. Some of the species are 
subject to great variation in the size and number of fuscous spots to the tegmina.

AN icaraguan specimen is figured. Walker! gave the origin of his type (2. smaragdina) 
as “West coast of America,” which habitat appears, from what I have observed with 
others of Walker's species thus localized, to be clearly referable to the Central-American 
region. Walker’s figure is without structural detail ; and no reference is made to it either 
in the description in part 1, or in the index appended to part 4 of his list. The spe- 
cimens he has described as Z. angulosa are clearly faded female forms of Z. smaragdina. 
As in the following species, the macular markings of the tegmina are most inconstant, 
being either in agreement with typical forms, as the one here figured, or becoming con- 
fluent and forming an irregular transverse fascia. The three apical marginal spots are 
sometimes followed by two or three others. In one specimen examined these macular 
markings are asymmetrical on the right and left tegmina. 
2. Zammara calochroma. (Tab. I. figg. 5, 5a, 56.) 
Zammara calochroma, Walk. List Hom. Suppl. p. 4’. 
Zammara smaragdula, Walk. Ins. Saund. Hom. p. 4. 
Zammara callichroma, Stal, Stett. ent. Zeit. xxv. p. 57 *, 
Hab. Muxtco2 (coll. Sallé, Mus. Berol.), Ovizaba (Bilimek, Mus. Vind. Ces.); Panama 
(Boucard).—Cotomsia, Bogota !, Rio Magdalena (Dr. Thieme, eoll. Oberthiir). 
The specimen figured is a typical Z. calochroma, Walk., from Mexico, in which the 
tegmina are ornamented with confluent fuscous macular markings, and: agrees generally 
with the form described by Stal, of which, by the courtesy of Dr. Aurivillius, I have 
been enabled to examine a specimen. These fuscous markings become frequently less 
confluent and more diminished in area till the form Z. smaragdula, Walk., is reached, 
and again decrease in number and size, so that in a female specimen from Panama 
which is now before me they are only faintly indicated. The structural characters of 
the underside, however, are very distinct; and the pattern and markings of the pro- and 
mesonotum are always constant.
