THREE NEW SPECIES OF MYRMELEONIDAE 
By Nathan Banks 
Dr. J. Bequaert on his recent trip to Arizona collected, 
with Mr. E. R. Tinkham, specimens of a new Myrmeleonid 
of the genus Eremoleon. It was found in a mine-shaft, and 
doubtless occurs in caves. The specimens are pale, the 
markings, although slight, are distinct, so that they are not 
teneral. This makes four species of this genus in the United 
States, others occur in Mexico. 
Mr. John L. Sperry has recently sent me a small Myrme- 
leonid taken by himself and wife in California. It is a new 
species of Clathroneuria distinguished from all others by 
the very short tibial spurs. 
I have added the description of a new form from the West 
Indies, a species of Puren whose known species occur in the 
western United States, Baja California, and Chile. 
Eremoleon pallens, sp. nov. 
Head and thorax pale yellowish, a faint brown mark 
above antennae, sometimes faint brown spots on vertex ; tip 
of antennae black, before it is a stretch of pale, and the basal 
half mostly pale, but more or less marked, mostly above, 
with dark; palpi scarcely dark at tips; pronotum has the 
front part more or less pale brown, with a narrow median 
pale stripe, behind with two submedian brown stripes, some- 
times scarcely indicated, and a short lateral pale brown 
stripe; thorax above with pale brown areas, more or less 
separated; pleura pale; abdomen pale, with dark bands 
above at near tip of several segments, much as in E. nigri- 
basis, but the dark on the segments tends to spread forward 
in middle, so sometimes the segment is largely dark above. 
Legs pale, tips of femora and tip and subbasal spot on tibiae 
dark. 
Fore wings without the basal black spot of E. nigribasis 
and without the clouds on radials of E. macer, few of the 
cross-veins brown-bordered ; the subcosta, radius and cubitus 
are interrupted with dark spots or streaks; there are four 
distinct almost black marks, all small ; one at the connection 
of anal and cubital fork, one at the rhegma, one at and above
