ments, while the White Grubs proper, the larv^ of Lcichnostenia, will 

 lie in a half-coil on their sides, or make awkward efforts to use their feet,, 

 being essentially burrowers. It is for these reasons that I have figured 

 the larva of Allorhiua on its back, as shown in the acconipanyiug illustra- 

 tion, (Figure 6).

The larvae of the Green June Beetle attract more attention than the 

 others, partly because they are somewhat larger in size, and partly because 

 they occur abundantly every year and are more easily brought by disturb- 

 ances and by irrigation to the surface of the ground. The parent beet- 

 les begin to fly the latter part of June, increase somewhat in numbers 

 during July and August, and disappear in September. Like the other 

 species of its sub-family this Green June Bug does not devour the leaver, 

 like the true May Beetles, but feeds upon over-ripe fruit and vegetables. 

 It is fond of clustering in numbers upon anything that is over-ripe or 

 half decayed, especially half decayed melons, and does in this way more 

 or less damage to rii)e peaches hanging on the tree. It will swarm 

 around the flowing sap of fruit trees or even of young oaks and maples,, 

 wherever there is a braise inducing such flow, and I have noticed that 

 they are particularly fond of feeding at the moisture that frequently re- 

 sults from the attacks of borers. A closely allied species, Euryomia mel- 

 ancholka is commonly known as the Fig-eater from its similar habit of 

 attacking fully ripe or over-ripe figs. Nevertheless the damage which 

 the parent beetle does is slight compared with the injury Avhich the 

 species often does in the larva state. 



Although so common, the readers of this bulletin Avill be surprised to 

 learn that there is a great deal yet to learn in reference to it, and that its 

 full life-history has not been traced. This is largely due to the fact that 

 the larva works under ground and out of sight, and to the further fact 

 that it is somewhat difficult to rear in confinement. I received two spec- 

 imens of this larva in Novemlierj 1868, from Mr. G. D. Baker, of South 

 Pass, Ills., who found them in his strawberry beds in company with one of 

 the May Beetle larva?, and it was at once noticeable that this Gi-een June 

 Bug differed from all I had up to that time studied in its peculiar habit 

 of crawling on its back, traveling with the same motion and quite as 

 rapidly as an ordinary caterpillar, and invariably turning on its back to 

 move or to burrow. These larvse remained alive in -doors, feeding greed-
