THE AMERICAN ENTOMOLOGIST. 



glad if thy time will allow some attention to the 

 subject. — S. A. Conard, West Giove P. O. 



The insect proves to be a species of Aleurodes 

 in different stages of development. The eggs 

 are elongate-oval and of a very light bluish- 

 green color, more whitish toward the margins. 

 They are pretty firmly attached to the surface of 

 the leaf in an upright position by a short spini- 

 form thread. Only one larva was to be found. 

 It is elongate, and of a light green color. Both 

 egg and young larva are difficult to observe, as 

 they are quite small. The pupa is ova', flattened 

 on two sides, uniformly greenish-white with the 

 dark ej'es visible through the delicate and trans- 

 parent shell. It is always firmly fastened to the 

 leaf. Of winged imagos there are quite a number, 

 both males and females, the sexes differing princi- 

 pally in theform of the abdomen. Thecoloi of this 

 winged form is bright yellow, eyes brown, an- 

 tennx, wings and legs white. This white color dis- 

 appears entirely when the specimens are mounted 

 in balsam, a fact which shows the importance of 

 describing these insects from living specimens. 

 The species is doubtless undescribed, as very 

 little or no attention has so far been paid to this 

 interesting family in this country. 



Larvae in stomach of Black Bass. — S. ./. /■'., 

 Normal, III. — Of the two larvx you send us 

 as having been found in the stomach of a Black 

 Bass {Microptcnis salmoidcs). one is too imperfect 

 to admit of determination. All that can be said 

 about it is that it is a Coleopterous larva, perhaps 

 belonging to the Dnscillidiv. The other larva 

 belongs to the Dytiscidic, is allied to Cy/>i.sl>T, but 

 differs in the form of the head. From the larva 

 oi Dylisciis it differs by its very slender maxillary 

 palpi. We take it to be the larva of either Lac- 

 cophilus or Hydrocanthus, several species of which 

 are very common. 



Insects from Stomach of Rock Bass. — 1 take 

 it for granted that you will be at least as much 

 interested in the subject of the food of fishes as in 

 that of the food of birds, and I therefore send you 

 a minute larva (or a part of one) which is not un- 

 common in the stomachs of Rock Bass and Sun- 

 fishes taken in the Illinois River in July. It is 

 sometimes associated with such aquatic insects 

 as Corixa tumida, Hydroporus, and larvae of Cki- 

 ronomoHs ; and sometimes (in the common Sun- 

 fish, Lepiopomus pallidus) with terrestrial insects 

 washed in. I send you as nearly perfect an in- 

 dividual as I have found, taken from the latter 

 species. — S. A, Forbes, Normal, 111. 



Unfortunately the specimen sent by Prof. 

 Forbes came to hand with the anal portion, which 

 is of so much importance in determining many 

 Coleopterous larvae, (for such it is) entirely want- 

 ing. From the general structure of the remainder 

 of the body we should say that it might be the 

 larva of Cyphon, in which event it is not strictly 

 aquatic but was washed into the water with 

 mud. That it is Coleopterous there is no ques- 



tion ; that it is not aquatic is more than probable ; 

 but for the rest there is no certainty. 



New Enemy to Sugar Cane.— The beetles 

 of which I send you with this a few specimens 

 have appeared in large quantities upon many of 

 our sugar plantations, and are doing very much 

 damage to our small canes. They eat to the 

 centre of the cane under ground and destroy the 

 inside just above the mother stock for some two 

 inches. As many as 56 have been found in 15 

 inches length of row They threaten to become 

 a verv serious pest. Can you give me any informa- 

 tion regarding them and what means, if any, can 

 be taken to protect the sugar plants from them? 

 — D. Th., Pattersonville, St. Mary's Parish, La. 



The species is Ligyrus rugiceps and has been 

 previously reported to us from the same region 

 of country, especially from Baton Rouge, as in- 

 jurious to young corn and grasses, in the same

manner as decsribed by our correspondent to 

 sugar cane. We cannot find that this habit of 

 injuring sugar cane by this beetle has been any- 

 where previously recorded. The natural history 

 of this species is absolutely unkfiown, so that it 

 is impossible to suggest any remedy based there- 

 on. The beetles are no doubt attracted by light, 

 and might be killed in great numbers by use of 

 the ordinary lamps and kerosene pans employed 

 to attract the Cotton Moth and illustrated in the 

 recent Bulletin which we issued on that insect. 

 We reproduce a figure of one of the simpler 

 forms of these lamps, the pan of which should 

 be partly filled with water and kerosene.
