THE STATE ENTOMOLOGIST. 135 



naturally expect to find its gall more common ; 2d, because on sev- 

 eral occasions I have found within the Gelechia gall, a pale worm 

 very different from the true gray gall-making larva. But until more 

 decided proof can be obtained, and until the fact is settled by further 

 experience and experiment, we must, from such evidence as we have, 

 consider the Misnamed Gall-moth, a true gall-maker. 



Thus we have three different and distinct gall-moths in this 

 country, belonging to two distinct families and three distinct genera ; 

 while a fourth ( Cochylis Mlarana) belonging to still another genus is 

 known to form a gall on the stems of Artemisiain. Europe. It is very 

 manifest that all of these galls are formed by the irritating gnawings 

 of the larva after it is hatched, and not induced by any poisonous fluid 

 injected with the egg by the ovipositor of the*parent, as is demon- 

 strably the case with those galls which are produced by gallflies 

 {Gynips family), and with such as are produced by some gall-making 

 Saw-flies. It is not at all improbable, however, that these moth larvae 

 do in reality secrete from the mouth some peculiar fluid which tends 

 to produce the gall ; for we know that very many other moth larvae 

 burrow in the stems of different plants without producing any 

 abnormal swelling.
