new North- American Insects. 323 



Aspidiotus Fernaldi, sp. n. 



Tin's name is applied to a puzzling form found by Mr. Kirk- 

 land on Gleditschia triacanthos in Charlesbank Park, Boston. 

 The scale resembles that of A. Forbesii, but the exuviae, at 

 least in the specimens seen by me, are dark brown. The 

 female insect is also like A. Forbesii, but the median lobes 

 are broad and practically entire, just like those of A. ostrece- 

 formis. From ostreceformis it is easily distinguished by the 

 great inequality of the chitinous processes at the first inter- 

 lobular interval ; the inner of these processes is straight, 

 instead of being curved as in Forbesii, the inequality being 

 about the same as in Forbesii. A. Fernaldi also differs from 

 ostreceformis in the close proximity of the second lobe to the 

 first; the second lobe is usually more developed and less 

 notched than in Forbesii. 



Mr. W. G. Johnson, when describing Forbesii, enumerates 

 its food-plants, and adds that it occurs " possibly " on honey- 

 locust. I suppose it probable that he found A. Fernaldi on 

 the honey-locust, and was in doubt as to whether it was 

 distinct. It may fairly be said of A. Fernaldi that it has 

 about the same relation to A. Forbesii that A. ostreceformis 

 has to A. ancylus. A. Fernaldi has five groups of circum- 

 genital glands, the median group of three, anterior laterals 

 4 to 9, posterior laterals 2 to 7. 



The specimens were sent to me by Mr. R. A. Cooley, of 

 the Massachusetts Agricultural College. The species is 

 named after the well-known entomologist of that institution. 



A. ancylus, Putn., was found by Mr. Kirkland on the 

 Gleditschia triacanthos in Charlesbank Park along with the 

 A. Fernaldi. It was also found on the same food-plant by 

 Mr. Cooley at Everett, Mass., here not accompanied by 

 Fernaldi. 



III. — The first-described Ercmopedes (Fam. Locustidae). 



Eremopedes Scudderi, sp. n. 



? . — Length of body 19-21 millim., of pronotuin 6 millim., 

 of hind femora 21^ millim., of hind tibia? 23 millim., of ovi- 

 positor 19-20 millim., of antennae about 51 millim. 



Sepia-brown in effect, but in reality ochreous, closely and 

 finely marbled with blackish ; the density of the black 

 marbling somewhat variable, but the lateral margins of the 

 pronotum always broadly pale ochreous. Pronotum truncate 

 in front and behind, the margin narrowly castaneous and
