CORRESPONDENCE. 



LARV,« OF XYELID.t. 



Sir,— The Wiener Ent. Zeit. for March, 1899 (Vol. XVIIL, p. 41). 

 pubUshes an article by Mr. F. W. Konow, in which my description of 

 Pleiironeura aviiiigrata is attacked. I do not desire to enter any con- 

 troversy in which the use of abusive language prevails, but as Mr. Konow 

 asks some direct questions about the larva, I propose to answer them for 

 his information, i. The abdominal feet are present on all the segments, 

 but quite small on the first and ninth, so that from the living larva I did 

 not describe them on these segments ; in the inflated larva they are fairly 

 distinct. Compare Mr. Young's description of Macroxyela /errtigi?iea 

 (Can. Ent., XXXI., 41), where the feet are even more prominent. 

 2. There are no anal stylets present. 3. The antennae are 6-jointed, 

 situated just below and a little inward from the eyes. 4. The palpi are 

 visible on the outside of the jaws when these are closed. 5. The length 

 of the mature larva is about 27 mm. 6. Mr. Konow asks how the larvae 

 may be distinguished from the Lydidse. I refer to my definition of the 

 Xyelids, Can. Ent., XXX., 176. Harrison G. Dyar.

To the Editor Canadia?i Entomologist : 



Sir, — I have read with much interest Prof. Enzio Renter's article in 

 the January number of the Canadian Entomologist, referring to the 

 occurrence of the apple fruit miner, Argyresthia conjugella, in Finland, 

 and I think the enclosed letter from Prof. Matsumura, of Japan, may 

 prove of interest to the readers of the Canadian Entomologist. You 

 will notice that his account of the Japanese pest, particularly with regard 

 to its attack, tallies very well with what we have observed in British 

 Columbia. The cocoon sent by Prof. Matsumura I am saving, and hope 

 to succeed in breeding the imago next spring. I am unable to deter- 

 mine positively by the cocoon if the insects are identical. I think that 

 the important point as to the mode of egg-laying must be determined 

 before we can feel satisfied with our knowledge of it. All of Prof. 

 Reuter's notes are of great interest to us here, but I cannot help thinking 

 that the mention made of this insect attacking plums is a mistake, some 

 observer having probably confounded the larvae of Setnasia pi-univora 

 with those of Argyresthia,. . E. A. Carew-Gibson,
