THE LEPIDOPTEklST 103 



pae and from these only three specimens emerged : 

 two badly crippled Catocalae, which perhaps were 

 similis f. aholah and one specimen of a Homoptera. 

 This one came from a small lot of larvae in which 

 the head structure was different from all the other 

 larvae, but we had not thought that this group might 

 give rise to a species of Homoptera. The other pu- 

 pae transformed into adults but were too weak to 

 break the pupa shell and thus died inside of it. This 

 sad experience will be a lesson for us when we go 

 South again. The next time we will stay there till 

 our Catocala larvae have pupated. We have at least 

 the satisfaction of knowing where to look for them. 



During our hunt for Catocala larvae we came 

 across a 'water-oak" in which there were numerous 

 holes which were apparently caused by a species of 

 Cossus inhabiting this tree. While we were still con- 

 sidering the possibility of finding Cossus specimens at 

 that season, Mr. Cassino suddenly pointed to some- 

 thing that looked like a knob in the bark. A second 

 look proved to our pleasant surprise that it was a 

 freshly emerged female of some Cossus species. A 

 few moments later we found the pupa shell, still soft, 

 protruding from the tree. The opportunity to obtain 

 additional specimens was so good that we decided to 

 trap the whole trunk as high as possible. The needed 

 supplies were obtained in the next village, and with the 

 help of fallen trees and large stones to stand upon, we 

 were able to cover ten feet of the trunk. A number 

 of small sticks were used to hold the cloth off the 

 tree so that the specimens after emerging would find 

 space enough for their development. On the after- 

 noon of the next day we made our first inspection and 

 to our joy found one male and one female. The next 

 day we found another male, the last one. Apparently 

 we had made the discovery at the very end of the 

 flying period of that species. Without going into de- 

 tails it may be mentioned that it is perhaps an unde- 

 scribed species, for neither sex agrees with anyone of 

 the known Cossids.
