with pulcherrimus and delicatus, the third with insolitus , excelsus, and 
innubus. Thus the species is not as unique as Banks supposed, and 
his generic name must be added to the synonymy of Epipompilus. I 
have seen no specimens of this species other than Banks’ type.

Remarks. — Bradley has recently provided a detailed description 
of this species, drawn from Cresson’s type of azteca. He states that 
this specimen “does not at all agree with Kohl’s description of maxi- 
miliani\ Since I found myself unable to agree with this statement, I 
asked to borrow the type of maximiliani from the Vienna Museum 
for comparison. At first the type could not be located, but later Dr. 
R. M. Bohart visited the museum and at my request searched for 
and found it; Dr. Max Fischer then sent it to me by mail, and I took 
it to Philadelphia and compared it directly with the type of azteca. 
I am very much indebted to Drs. Bohart and Fischer for their assis- 
tance with this problem. 
The two type specimens differ considerably in size, that of aztecus 
being much larger, 13.5 mm. long, fore wing 10 mm.; maximiliani 
measures 7.5 mm. long, fore wing 6 mm. The front femora are slight- 
ly more incrassate in aztecus (2.6 X as long as maximum width as 
compared to 2.75 X in maximiliani) . The whitish maculations are 
exactly the same in the two specimens, but they type of aztecus has 
the posterior third of the propodeum blackish and the middle and hind 
legs blackish except for the white spurs and white streaks on the hind 
tibiae; in the type of maximiliani the propodeum is wholly rufous, 
the middle and hind coxae rufous above, the middle and hind femora 
rufous, and the tibiae partially suffused with rufous. Besides these 
two specimens, I have seen one other, a female from Cuernavaca, 
taken by my wife inside the window of a house on March 24, 1959. 
This specimen is about the same size as the type of aztecus , from 
Veracruz, and the front femora are incrassate to the same degree. 
However, the propodeum is wholly rufous (as in the type of maximil- 
iani , also from Cuernavaca) and the leg coloration intermediate be- 
tween that of the two types (middle femora rufous, hind femora
