A NEW PULVINARIA FOUND ON ORCHIDS. 



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



Puivinaria brassies, n. sp. 



$ scale rather like Lecanium hesperidum, elongate-oval, flattish, 

 pale olive-brown, 2^ mm. long. Ovisac white, firm, elongate, parallel- 

 sided, distinctly longitudinally grooved, 8 mm. long, 2 broad. Derm 

 colourless, not tessellate. Margin with a double row of easily-deciduous, 

 strong, usually large, blunt spines, which are, near the lateral and posterior 

 clefts, more or less branched at their tips. Spines of lateral clefts in 

 threes, one very long and large, two very short and small. Anal plates 

 brown, longer than broad, their outer sides meeting at about a right angle. 

 Each plate with three small spines at tip, and three large bristles on outer 

 hind margin. Anogenital ring with six stout hairs. Rostral loop reach- 

 ing to level of insertion of middle pair of legs. Antennae 8-jointed ; 3 

 longest, but not greatly so. Formula 32 (458) 167. Two and 5 each with 

 a long hair ; 8 with several long hairs. Legs ordinary ; coxa more than 

 half as long as trochanter -f femur. Trochanter with a strong, but not 

 very long, bristle. Claw short, stout, curved. Tarsal digitules long, 

 moderately stout, distinctly knobbed. Digitules of claw extremely stout, 

 gradually widening to the large knobs. 



Hab. — On leaves of Brassia verrucosa, a native of Mexico, in 

 greenhouse at Ottawa, Dec. 15th, 1894 (J. Fletcher). The actual plant 

 was purchased from a New Jersey florist, and the insect has been found 

 on no other in the house. It is quite a distinct and peculiar form of the 

 type of P. camcllice, but smaller, with a much narrower, ribbed ovisac. I 

 regret that I have not seen the description of P. linearis, Targ., 1885, 

 found on Camellia japonica, but it is doubtless safe to assume that it 

 cannot be that species. 



THE USE OF MEGALOPYGE. 



BY A. R. GROTE, A. M., BREMEN, GERMANY. 



In the able and original paper on " Evolution and Taxonomy," by 

 my friend, Prof. Comstock, published in 1893, is a note, on page 103, 

 relating to the use of the generic title Megalopyge. The author says, refer- 

 ring to Berg's (not "Berge") articles on Argentine Lepidoptera : "This 

 monograph seems to have been overlooked by American writers." This 

 seems not quite correct. In Papilio, Vol. 3, 106-8, I have published (1883) 

 a review of these papers by C. Berg. I took, in the course of a lengthy
