INSECTS INJURIOUS TO GARDEN AND ORCHARD CROPS. 



experiments. One beetle died in a few days, and as no more were 

 captured no further attention was paid the matter until May 31, when 

 examination of the sand showed the presence of both eggs and larva? — 

 six of the former and three of the latter. All of the remaining eggs 

 had hatched by June 2, when another had been deposited. From this 

 lot the accompanying observations were made and the descriptions 

 which immediately follow were drawn. 



DESCRIPTIVE. 



The egg. — The egg is nearly spherical, resembling in miniature those 

 of certain of the smaller owls. It is of quite firm consistency and 

 elastic. The color, when newly laid, is perfectly white, and rather 

 moderately polished, but with age this becomes darker gray and 

 opaque. There is no visible sculpture. The size, when freshly depos- 

 ited, is about 1.75 U1U1 by 1.50 nn ", but by absorption this becomes, iinnie-

diately before hatching, about 2.65 mm by 2.1 8™ m , or at least a third 

 larger. An egg is shown in outline at b of figure 15. 



The newly-hatched larva. — The larva, when first hatched, is nearly 

 white in color and moderately hairy. The head is dull yellowish, as 

 are also the terminal joints of the legs. The mandibles are brown, 

 becoming dark toward the extreme toothed tips, and, by comparison 

 with those of Lachnosterna, are small. The general appearance of 

 this stage is represented in the illustration at c. When extended at 

 length, it measures about 4.5 mm by 1.7 mm . 



The mature larva. — The larva when fully matured presents the appear- 

 ance of d of the accompanying figure. It is far more robust than Lach- 

 nosterna, the abdomen particularly being much swollen, while the legs 

 are much shorter, the head smaller, and the maudibles less prominent, in 

 whicli respects it resembles Allorhina. The spiracles ai e prominent, and 

 in front of the spiracle of the first thoracic segment there is a yellow 

 corneous plate of sab triangular outline. Upon attaining full maturity 

 the larva reaches a great size; the skin becomes distended with the 

 contents of the abdomen, which imparts to the lower moiety of the 

 body a dull deep leaden hue not indicated in the illustration. A larva
