TWO NEW SCALE INSECTS. 

 By T. D. A. Cockerell. 



Lecanium perlatum, n. sp. 



Female scales on under side of leaf, broad and flat, much 

 like L. tessellatum ; chestnut colour, smooth and shiny, surface 

 malleate, form oblique, 7 mm. long, 7 mm. broad. Legs ex- 

 tremely small, about the size of those of L. hesperidum, of 

 ordinary form, trochanter with a long bristle, femur only mode- 

 rately stout, tibia about three-quarters the length of femur, 

 tarsus about half as long as tibia, claw short and stout, its digi- 

 tules extending considerably beyond its tip. Antennae 8-jointed, 

 formula approximately (23) (45) (16) (78), 4 and 5 are not much 

 shorter than 3, 1 with a short hair, 5 with a long hair, 6, 7, and 

 8 each with a lateral hair (8 with two), and 8 with three terminal 

 hairs, one very long. Dermis brown, with large oval and round 

 glands, not reticulated. Hairs of margin extremely small and 

 few in number. Stigmatal spines in threes, two small and one 

 large. 



Hob. Ponta Delgada, Azores ; on orange trees. (Div. Ent. 

 U.S. Dep. Agr., No. 7312.) 



L. perlatum is a very distinct and interesting species. It was 

 sent to me for study by Dr. L. 0. Howard, to whom I trans- 

 mitted a description. Dr. Howard informs me that he forwarded 

 the MS. to Prof. Chaves in the Azores, who will publish it there ; 

 but for the convenience of students it is deemed wise to send a 

 copy to a widely-read entomological journal. 



Aspidiotus juglans-regice var. kafkee, n.var. 



Mr. Karl L. Kafka sends me an apparently new form of 

 Aspidiotus, found on bark of Fraxinus excelsior in Vienna. 

 Curiously, it approaches our American A. juglans-regice, Comst., 

 so much so, that I propose to call it A. juglans-regice var. kafkee, 

 new var. The female scale is circular, 2£ mm. diam., flat, very 

 dark grey or blackish, exactly the colour of the bark ; exuviae 

 subcentral or sublateral, covered, orange-reddish. Removed 

 from the bark the scale leaves a white mark. Male scale small 

 and elongate, about twice as long as broad. Female insect like 

 juglans-regice, but glandular thickening at inner base of median 

 lobes larger than or as large as that at outer base ; the rounded 

 orifice, which in juglans-regice is close to thickening of outer 

 base, is in kafkee beneath or just laterad of thickening of inner 

 base ; the median lobes in kafkee are a little further apart, and 

 hardly so produced as in juglans-regice. Five groups of ventral 

 glands, median 2 or only one, caudo-laterals 9, cephalo-laterals 

 10. First row of transversely oval glands, starting at the de-
