HYPHINOE. — 75 
variable in size (10-15 millim.), and to a certain extent in shape. As a rule, the 
pronotum is strongly raised in front and abruptly declivous before the apex; but in 
several examples it is only sinuate and almost straight. In the collection of the Vienna 
Museum there is a specimen, set on one side apparently as a new species, which belongs 
to this variety, and there are several others in our collection, mostly from high alti- 
tudes. The shape of the front of the pronotum is also variable ; in a male specimen 
from the Volcan de Chiriqui the pronotal horns are much more marked than is usual 
in the species, and it might with reason be described as a new species if it were not 
considered as one of a series. In Signoret’s collection there is a specimen, separated 
apparently on a much slighter difference in the shape of the front of the pronotum, 
under the name “ fairmairei.” I cannot, however, find that the description has been 
published. There are a considerable number of these unpublished species in collec- 
tions, and they cause infinite trouble, as, unless the fact of their not having been 
published is mentioned, one cannot be certain that the reference has not been missed, 
and much time is wasted in a fruitless search forthe name. Worse than this, however, 
is the publication of descriptions without locality ; four out of six species of Alemeone 
in the British Museum are so described, and the “ Amer. bor.” or “ Amer. mer.” of 
the earlier writers are almost as bad as no locality at all. The difficulty of identifying 
the species in Stal’s ‘ Hemiptera Fabriciana’ is greatly increased by the fact that he is 
obliged to give ‘“‘ America meridionalis” so often as the sole locality.

Hab. Guatemata (Sallé +). 
M. Fallou’s specimen, from the description, is a male, and the four specimens which 
I have seen are also males; one of these is in our collection, and I have received two 
from the Belgian Museum ard one from the Stockholm Museum, all undetermined. 
It is a very conspicuous species, being entirely of a lighter or darker violaceous-brown 
or violaceous colour, with a clearly marked whitish-yellow lateral line on eauh side at 
the margins, and the tibie and tarsi testaceous. As M. Fallou’s description is some- 
what isolated I append it :—“ Brun violacé. Cuisses de méme couleur, avec les pattes 
et les tarses jaunes. Prothorax trés renflé, formant un énorme bourrelet 4 la partie 
supérieure et terminé par une épine aigué noire, n’atteignant pas l’extrémité des 
élytres. Une bande jaune claire part de chaque cété du bourrelet du prothorax 
et longe la suture jusqu’a la tache noire de la pointe. Ces bandes jaunes sont elles- 
mémes bordées d’un trait noir. Elytres de méme couleur que le prothorax. Long. 
17 mm.” 
M. Fallou has kindly sent me the type; there isa specimen in the Royal Belgian 
Museum exactly agreeing with it, but the other examples are of a uniform dark
