In another cage one was deposited two (lays after external 

 appearance. 



In another cage one was retained for six days after exter- 

 nal appearance. 



Egg masses unfavorably deposited usually are devoured 

 by other cockroaches or even by the mother. 



Not one cockroach of this species deposited an ootheca 

 upon thin paper. I have had some imbedded into the larger 

 pores of sponges kept saturated with water as a source of 

 moisture in the cages. Such oothecae were packed over 

 with bits of sponge torn from the large piece precisely for the 

 purpose of concealing the deposited oothecae. Often bits 

 of rag or bread are utilized and in several instances I have 

 seen oothecae of this species completely covered over and 

 concealed by fine bits of dried cockroach dung. When no 

 covering material is available the oothecae may be dropped 

 at random or simply pasted to articles and not covered. 



Notes on American Rhynchophora (Col,), 



By J. Wagener Green, Easton, Pennsylvania. 



The Texan material cited in the following pages was col-

 notices of two other new species and some miscellaneous 

 observations.

 occiput smooth, with few coarse punctures; genae transversely wrinkled. 

 Beak as long as head and thorax; coarsely, densely, rugosely punctured 

 throughout; sulcate at the sides; tricarinate above from base to antennal 

 insertion, .'\ntennae inserted before the middle of beak; as compared 

 with those of bicolor, joints three, four and five are more slender and elong-
