Zenodoxus is readily distinguished by having both pairs of wings 

 opaque. The antennae are moderate, tapering to the tip, linear, biciliate. 

 Thorax heavy, globose, widening posteriorly. ' Abdomen very short and 

 wide, somewhat flattened ; anal tuft short, broad and squarely cut. 



As similar characters are not used by authors, it is not possible to 

 give a synoptic table of the genera. There are some slight differences of 

 venation, which in the European genera are carefully described, but these 1 

 have not mentioned, since our American genera are not so described as 

 to allow of comparison. 



The following letter has been received from JMr. A. G. Butler : 



Deal- Sir : — I think the following note may interest American Lepi- 

 dopterists- in the matter of BoUiia fasciolaris. 



The fact that Boliua fasciolaris was the male of B. amcaris was 

 practically illustrated in the Museum by a mistake made by the late Mr. 

 F. Walker. One of the specimens enumerated by him is B. ciinearis 

 (from ' Hrazii ') it differs in no respect from the other females separated 

 under the latter name : our males are from St. Domingo and the Ama- 

 zons, t>ur females from St. Domingo, the Amazons, Venezuela, West 

 Coast of America and Veragua. It is by no means certain that a species 

 with so wide a range does not occur in North America and in Grote's 

 collection there is a specimen (unfortunately not labelled with its locality) 

 of typical male B. fasciolaris. 



Assuming that the latter is the male of B. cunearis, which appears 

 to me to be certain, it is highly probable that B. ochreipennis is also the 

 male of B. nigrescens; our specimens of the former are all males, those of 

 the latter females ; the diiferences are equivalent to those between B. 

 fasciolaris and B. ciinearis. 



Yours very truly, 



A. G. Butler. 



While pickmg apples, October 12, 1887, I found a thin oblong 

 cocoon between two apples, with a leaf drawn over part of its upper side. 

 November i, there came out a fine 9 Eugonia alniaria. The orchard 

 consists of apple and pear trees, and the nearest pear tree is about twent\ 

 feet from this one. I am not aware that Apple has been as yet known as 

 a food plant of this insect. M. S. Crane.
