side. It is .30 of an inch long. An insect that would be 

 readily mistaken for the liylobius pales is the Otiorhynclius sul- 

 catus of Fabriciiis (Fig. 464), which is of much the same color, 

 but with a thicker body. 



The Plum Gouger, Arithonomus x^runicida "VValsli, resembles 

 the Plum curculio in its habits, and, according to Walsh, is 

 equally as common in Northern and Central Illinois. It makes 

 a round puncture in the plum, sometimes five or six, from 

 which the gum copiously exudes. Instead of living, however, 

 in the pulp, it devours the kernel and usuall}" transforms inside 

 the stone of the fruit. "The thorax of the plum gouger is 

 ochre-yellow ; the head and hinder parts slate-color, the latter 

 Avith irregular white and black spots. In common with the 

 other species of the genus to which it belongs its snout usually 

 projects forward, whereas that of the Curculio usuallj^ hangs 

 perpendicularly'- downwards." (Walsh.) A. sycophanta Walsh 

 is brown-black and was bred b}^ Mr. Walsh from the galls of 

 various saw-flies found on the willow, and he supposes that this 

 species, "while in the larva state, must destroy the egg or the 

 very young larva of the gall-making Nematus, just as A. cra- 

 tcegi Walsh evidently does ; which was found in an undescribed 

 Cecidomyian gall on the thorn bush, and just as the larva of 

 A. scutellatus Schonh. gradually destroys the young plant-lice 

 among which it lives ; otherwise the two larvse would exist in 

 the same gall." Walsh has also bred A. tessellatus Walsh from 

 the Cecidomyian gall, C. s. brassicoides. It is "a very con- 

 stant species and easily recognizable by the tessellate appear- 

 ance of the elytra." A. quadrigihhus Say punctures the apple, 

 making from one to twenty holes in the fruit. 



The Cranberry weevil, as we may call it, or the AntJionomus 

 sutxLralis Lee, is a minute reddish broAvn beetle, with the beak 

 one-half as long as the bod}', just bej'ond the middle of which 

 the antennae are inserted. The head is darker than the rest 

 of the bod}', being brown black. The thorax is a little darker 

 than the elytra and covered very sparsely with short Avhitish 

 hairs ; the scutellum is whitish, and the elytra are shining red- 

 dish brown, with the striae deeply punctured, the interstices 

 being smooth. It is .13 of an inch long including the beak.
