This species appears to be by far the most abundant of the genus in Central America. 
It is very variable in size and also in colour; the specimens from Chilpancingo are of 
a bright sulphur-yellow, whereas the majority are more or less orange, and small light 
yellow, almost greyish specimens occur; the black markings are also variable. ‘The 
larger specimens attain a length of 9 or even 10 millim., whereas the smaller -do not 
exceed 6 millim. In Signoret’s collection the larger specimens, which we regard as 
M. mewicana, are placed under M. stolida, whereas the small light specimens are 
referred to M. mexicana; from the large series in our collection it is, however, 
evident that they belong to the same species. UM. sexmaculata is only a small light 
variety of the type form; Walker’s type is from Honduras, and exactly agrees with two 
specimens from Nicaragua in our collection. We figure a typical example from Chil- 
pancingo, and one of the var. sermaculata from Teapa.

There is a specimen in the Vienna Museum collection which appears to be a variety 
of this species, labelled “ Mexico, Puebla (Bilimek),” and I have found another in the 
collection of the Royal Belgian Museum, among the series of MV. tectigera, from 
Brazil; they may be representatives of a new species, but more specimens must: be 
examined before it can be described. This variety appears to differ from the type form 
in being less elevated, with the pronotum straight or almost straight before the apex, 
and the anterior white border not continued so far upwards; in shape it somewhat 
resembles the preceding species. 
6. Membracis humilis, sp. n. (Tab. I. figg. 6, 6a.) 
Nigra, minus elevata, sparsissime griseo-pubescens ; pronoto humili, haud super frontem producto, ante apicem 
- sinuato, maculis tribus lete albis, prima supra caput lata, secundé ad medium dorsi modica, et tertia ante 
apicem, apice ipso nigro ; tegminibus pedibusque nigris, illis longe ultra apicem pronoti extensis. 
Rather a small species, with the pronotum not. much elevated, black, with three white spots—one large and
