Psyche 
[June 
by slender isthmi. In an area about 27 mm. long and 8 mm. 
broad, where the abdomen of the insect was, the marking is 
absent, though it must have been originally present. The third 
and fourth bands are especially characteristic, having wedge- 
shaped marks with their bases on anal margin of wing, and above 
them, but separated from them, ovate spots, more or less pointed 
at the ends. The two outer bands consist of a series of large 
suboval spots united by slender or short bands. 
I am much indebted to Mr. Uvarov at the British Museum 
for calling my attention to similar characters in modern species. 
Thus the oblique cross-veins are beautifully shown in the genera 
Pseudophyllus and Cratylus, which however lack the color mark- 
ings. The cross-banding and spotting is well seen in other 
living genera, as in the Cystophyllid Sanaa imperialis White 
from India, which is beautifully shown in colors on one of the 
post-cards issued by the Museum. Much more like Aboilus 
besobrasovce in markings is Typhoplera donovani Donovan, also 
from India. 
Although it has nothing to do with the fossils, I venture to 
add a note on the extraordinary features of the South American 
Catasparata histrio Brunner, Mimetica picteti Kirby and Typho- 
phyllum mutilatun Walker which were shown to me by Uvarov. 
The tegmina are exactly like dry leaves, in some cases appearing 
as if spotted by fungi, but the extraordinary thing is that the 
males (only the males, as Uvarov noted) have on the costal 
margin a semicircular incision exactly as if cut by a Megachile 
bee. Megachile is of course richly represented in the same 
country. The simulation is perfect, but its biological significance 
is not so clear.
