268 ENTOMOLOGICAL NEWS. [ June, ’14 
constantly regular and in a straight line, while in margarita 
the band, while varying from a few spots to an almost con- 
tinuous band across the wing, is never straight, extending out 
almost to the outer angle, and the spots always varying in 
size, giving an appearance decidedly different from pittacus, 
and more like python, from which again it differs in size, color 
and shape of wing. 
*91. Thanaos persius Scud. 
Some of these, a long series, are remarkable for their very 
small size, a number being 16 mm. from center of thorax to 
tip of wing. 
In conclusion I wish to express my appreciation of the 
courtesies extended by Dr. Henry Skinner, Curator of the 
Entomological Section of the Academy of Natural Sciences of 
Philadelphia, and his valuable assistance and encouragement 
in the study of these insects.

Postpupal Development in Chilocorus bivulnerus Mulsant (Col.) 
Upon emerging from the pupal stage, the elytra of this beetle are 
tan-colored, with the red spots pallid, the head and thorax black; 
four hours later, the natural colors had developed. The pupae were 
numerous in the middle of June, 1900, at Annapolis, Maryland. 
An Ant-lion (Myrmeleonid) Without Food (Neur.) 
Several half-grown larvae of a common ant-lion occurring about 
Annapolis, Maryland, were kept in confinement (box full of sand) 
without feeding for twenty-five days, when they were thrown out. 
Culicid Pupa out of Water (Dip.) 
At Granite, Baltimore County, Maryland, the last of August, 1900, 
some mosquito pupae were found in water in a tree hollow; when 
transferring them to a tin can, one accidentally lodged upon the side 
of the can, remaining thus for about twenty hours. When it was 
washed down into the water it moved off at once, apparently none 
the worse.
