MONOPHLEBUS.—ICERYA. 3 
The following males may belong to one or the other of the four species enumerated, 
and it is therefore inadvisable to name them :— 
Monophlebus, sp. 
3d. Expanse of wings about 16 millim. Head, body, legs, and antenne ferruginous; eyes bright scarlet; 
abdomen thinly covered with cottony secretion, and presenting eight long fleshy caudal processes covered 
with short hairs. Wings black, with the usual broad red costa and two white streaks. 
Hab. Panama: Volcan de Chiriqui 3000 feet (Champion). 
In size and coloration resembles the African UM. raddoni, Westw., but that has the 
thoracic dorsum piceous. This and the two following males are particularly interesting, 
because they show that the Monophlebus-like insects of Central America, variously 
referred to Ortonia and Llaveia, have indeed in the male, as well as in the female, the 
structure of true Monophlebus. As four species are known from our region from the 
female only, it is probable that some or all of these males belong with them; hence no 
names are proposed for the males, although several species have been described in 
former years from the male alone. 
Monophlebus, sp. 
3. Expanse about 10 millim. Reddish; eyes, thoracic band, ventral surface of thorax, and legs black; 
antenne very dark brown; abdomen bright scarlet, practically naked, with only four long fleshy processes, 
‘which are brown. Wings black, with a red costa, but no white streaks. 
Hab. Panama: Volcan de Chiriqui 3000 feet (Champion). 
This departs from typical Monophlebus in having only four (instead of eight) caudal 
processes. It may possibly be the male of Protortonia, in which case that name might 
well be used in a subgeneric sense, 
Monophlebus, sp. 
3. Expanse about 10 millim. Dull red; head, except the occiput, antenne, legs, and pro- and mesothorax 
black; abdomen with eight fleshy processes, the first shorter than the rest; wings black, with the usual 
red costa, and two white lines, which are longer and finer than in the large species from Chiriqui. 
Hab. Mexico: Acaguizotla in Guerrero 3500 feet (H. H. Smith).
