A NEW ALEURODES ON OAK. 



BY T. D. A. COCKERELL, N. M. AGR. EXP. STA. 



Aleurodes gelatinosus, n. sp. — Pupa oval, rather less than i mm. 

 long, pitch black, not bearing the larval skin, margin beaded ; no fringe 

 of the ordinary kind, but the pupa is surrounded by and rests on a 

 gelatinous-looking colourless translucent substance, which extends rather 

 further from the margin than half the diameter of the pupa. Radiating 

 from the pupa, resting on the translucent substance, are three conspicuous 

 lines of white secretion, one from the caudal end, and one from each side 

 of the cephalic end. 



Adult with head and body very bright lemon yellow ; wings white, 

 semitransparent, spotless. Eyes not divided. Antennae with second 

 segment at least twice as long as the first ; formula for the slender seg- 

 ments 43576. 



Hab. — Pupse abundant on under sides of leaves of oak at Dripping 

 Spring, Organ Mts., New Mexico. Adults emerging the last week of 

 April. The oak, according to Prof. E. O. Wooton, is probably Quercus 

 arizonica, Sarg. 



AUTUMN CAPTURES. 



Our park caretaker unwittingly caters to the wants of the entomol- 

 ogist by planting every year some fine beds of Phlox Drummondii and 

 verbenas. Last year, without a net, I took with a cyanide bottle 59 

 Plusias in one evening about the 20th of September. I was surprised 

 to find that 22 of them were Biloba, the rest were Precationis. This 

 year I went to the park on the 17 th of Sept., better prepared for taking 

 anything I came across. I caught Phisia Balluca, one ; ^-Eroides, one ; 

 Simplex, several; and Precationis, ^. few; three Plusias of a species i,ot 

 yet determined; also two Deilephela lineata; but the capture of the 

 evening was a very fair specimen of Dilophonota obsaira, which was not 

 represented in my cabinet. I have two of ello, but this insect is at once 

 easily distinguished from it by the description quoted by Mr. Moffat in 

 the last annual report, viz., smaller size, light gray primaries, and 

 unhanded abdomen. I thought the capture was worth recording. I 

 have taken over 40 Heterocea, new to me this season, and my Orillia list 

 j§ now fairly respectable, C- E. Grant, Orillia, Ont,
