constantly regular and in a straight line, while in margdrita 

 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 pittacns, 

 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, iqoo, 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.
