April, '14] SCIENTIFIC NOTES 251 



Smith said: "It may be interesting to note that I believe that the entire infestation 

 in New Jersey has been destroyed and if any specimens do exist they are accidental 

 escapes left on the grounds when all infested plants were supposed to have been 

 destroyed. There was no sale of this stock through the New Jersey nurserymen." 



It is equally as interesting to note that in January, 1914, almost four years later, 

 the scale was found in large numbers infesting Japanese hemlock in tlie same part 

 of the state where it was originally discovered. It can therefore be said to have gained 

 a slight foothold. Apparently some accidental escapes were left on the grounds 

 when all infested plants were supposed to have been destroyed. This shows the 

 need of extremely close supervision in the case of scale infested imported plants. 

 It is unwise to try to pick out the infested plants and allow the apparently clean 

 ones of the shipment to come through, especially when stray scales are likely to be 

 overlooked. One can never be sure that the infestation has been entirely destroyed. 

 An attempt will be made again to wipe this scale out of New Jersey. 



Agrilus sinuatus Ohv. The work of this buprestid was first noted in New Jersey 

 in 1894 at which time it did considerable injury to pears in orchards and nurseries 

 in the northern part of the state. According to Bull. 109 of the New Jersey Agric. 

 Exp. Sta. by J. B. Smith it was probably introduced from France. In "Insects of 

 New Jersey" it is hsted as being local in Essex, Union and Middlesex Counties, 

 "an introduced species that is being gradually worked out." An additional county 

 can now be added to the list, namely Bergen . While it is true that it is not abundant, 

 every year, it is customary to run across its work in the northern part of the state. 

 In spite of the fact that it is no longer destructive, it is evidently holding its own in 

 a small way and spreading somewhat. 



Kaliosysphinga dohrnii Tischben. During the summer of 1913 this sawfly leaf 

 miner was first noticed in New Jeisey at Elizabeth on European alder, Alnus gluti- 

 nosa, growing in a nursery. The leaves were mined so badly that the trees presented 

 the appearance of having been swept by fire and the ground below was strewn with 

 dried leaves. This insect was first described in Germany in 1846. While mentioned 

 in Smith's "Insects of New Jersey," it is not recorded as occurring in New Jersey. 

 An account of this leaf miner can be found in Bull. 233, Cornell University Agric. 

 Exp. Sta., by M. V. Slingerland.

A Coleopterous (Clerid) Larva Predaceous On Codling Moth Larvae. This note 

 is to give only a word concerning an enemy of the codling moth larva that is 

 common in this locahty. Not having seen reference to this enemy elsewhere, I 

 give the note for the benefit of other workers and that more information may be 

 obtained for myself. Any detailed observations made later here will be announced. 



While examining some old bands for the codling moth in an abandoned orchard 

 near MesiUa Park, N. M., October 20, 1912, I found a coleopterous larva in the 

 cocoon of a codling moth larva. The latter was limp, the greater part of its body 

 juices having been sucked out. 



The predaceous larva was placed in the laboratory in a glass jar containing some 

 earth and fragments of tissue paper. A half dozen codling moth larvae were placed 

 in with it. In the spring I thought it had gone into the earth to pupate as I could 

 not see it as I had previously. So it was left until October 17, 1913. On that day 

 the tissue paper was carefully removed and the larva was found snugly curled up 

 in the emptied cocoon of a codling moth larva. The codUng moth larvaj had been 

 eaten before pupation. More of the food of this predaceous fellow was put in on 

 this day and it remains thrifty to the present date.
