LONG HORNED BEETLES. 117 



minute legs attached to the anterior segments. The pupa is about 

 the same size as the larva, of a whitish color, and is also shown 

 in its burrow. 



"Birds are active agents in the destruction of these larvae; 

 they seek them in their places of retreat and devour them. Should 

 they a't any time become very numerous they may easily be dis- 

 posed of by gathering the fallen branches and burning them 

 before the insect has time to mature." 



Several other beetles of this genus are also destructive, and 

 especially so in the orange-growing states, where the Unarmed 

 Girdler (E. inerme Newm.), destroys the twigs of orange trees. 

 It is called "unarmed" because the beetle lacks the two spines 

 at the tip of the elytra. Of course i!t is not necessary for our 

 fruit growers to prepare themselves to fight this beetle. 



THE TWO-SrOTTED HICKORY BORER. 



(Tylonotus bimaculatus Hald.), 



This beetle, (Fig. 121, Plate V), equal in size to the "apple- 

 tree primer," but broader, is a rather pretty insect, dark-brown, 

 with either two yellowish spots near the tips of the elytra, which 

 are unarmed, or with four spots, two of which form almost a band 

 across the wings. Our specimens in Minnesota are almost in- 

 variably four-spotted. 



The larva of this beetle feeds in the wood of hickory, but- 

 ternut, and walnut, and is sometimes quite numerous and corres- 

 pondingly injurious by destroying the terminal twigs of such use- 

 ful trees. It occurs also under the bark of the white or paper 

 birch, and in the ash. 



THE TWO-SPOTTED MOLORCHUS. 



. (Molorchus bimaculatus Say). 



This peculiar small beetle, about a third of an inch in 

 length, is not mentioned because it is very destructive, but be- 

 cause it differs from nearly all our longicorns in having the 

 wing-covers only half as long as the abdomen. It has a very
