ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE 



Callosamia Carolina and Samia securifera (Lepid., Saturnidae) 



Mr. \V. C. Dukes of Mobile, Alabama, has sent me a cocoon of Callos- 

 amia Carolina, described by F. M. Jones in this journal (Vol. XIX, p. 231, 

 1908). The type came from Berkeley County, South Carolina. In 

 Entomological News, XX, p. 49, 1909, Mr. Jones figured and fully de- 

 scribed the species. It is probably quite distinct from C. angulifera. 



In Beitrage Zur Schmetterlingskunde, Mossen and Weymer, (Elber- 

 feld, 1872), there is figured, in both sexes, what they call Samia securifera, 

 (figs. 50, 51) from Central America. This is probably the same species as 

 Carolina. Mr. Dukes has extended the range of Carolina and it will be 

 interesting to compare Central American species or specimens with Carolina 

 when thev are found. — Henry Skinner. 



Notes on the Oviposition and Food of the Wheel-bug (Arilus 

 cristatus Linn.) (^Hemip. Heter). 



During the months of September and October, 1917, the wheel-bug' 

 Arilus cristatus Linn, was very numerous on flowers, especially goldenrod- 

 along the Potomac river near Williamsport, Md. Fifty specimens could 

 easily be taken in the space of an hour — the females somewhat more numer- 

 ous than the males. 



On September 30, it was noticed that the adults were especially active 

 in copulation, although they were observed thus engaged several weeks 

 previous and somewhat later than this date. 



Females oviposited readily and usually deposited all of their eggs at one 

 laying and in one mass. For sixteen females that oviposited in captivity, 

 the largest number of eggs was 182, the smallest 60 and the average was 

 130.6. The exact number of individual eggs per female was 118, 60, 132, 

 144, 137, 152, 90, 126, 169, 97, 171, 182, 103, 148, 136 and 126. 



Eggs were deposited in rearing cages on the cover of salve boxes and on 

 the sides or top of screen cages. Masses were found in the field only on 

 the trunk and lower limbs of trees. 



Adults were found feeding on honey bees and grasshoppers in the field. 

 In cages they readily attacked and devoured kaytdids, adult Meloidae, 

 adults of Cyllene robiniae, Arctiid larvae, Pentatomid adults, and several 

 unknown Lepidopterous larvae. In addition, females were found to be 

 very fond of de\ouring the males soon after copulation was complete. —
