CURATOB OF THE GEOSVENOE MUBEUM, CHESTER.

 Leucaspis pini, A. C. P. Morgan, Ent. Mo. Mag., xxv, p. 189, pi. iii, 

 fig. 3 (1889) ; id., iii, n. s., p. 13 (1892). Newstead, Ent. Mo. 

 Mag., V, n. s., p. 181, fig. (1894). 



$ adult lying within the second moult ; the latter, however, is completely hidden 

 beneath the scale, which is entirely secreted at the 2nd stage. $ . Pygidium (figs. 



1, 2, 3) generally with two pairs of very short, rounded 

 lobes ; sometimes there are a third or even a fourth 

 „ , , - T pair, but these are inconstant and asvmetrical ; on 



/v p „2 ' ""a I either side beyond the median lobes are five or six 



(generally five) rather long spiny hairs, and between 

 them two very short ones ; within the margin are 

 two irregular rows of pores or spinnerets ; grouped 

 spinnerets arranged in the form of an arch, but 

 generally well separated : the anterior group consists 

 of from five to ten, the anterior laterals from ten to 

 twelve, and the posterior laterals from nine to twelve. 



Scale of the $ . In my description {I. c.) for " second moult yellow, &c.," read 

 " larval moult yellow, &c. ;" there is only the larval moult visible at the cephalic 

 extremity.. Larva rather short-ovate. Eyes black. Antennae of five joints ; 1st, 

 2nd, 3rd and 4th shortest, and in length nearly equal; 5th about as long as the rest 

 together, is strongly ringed, and has three very long hairs. Legs with coxa and 

 femur broad ; tibise and tarsi much thinner, the latter very short, only about the 

 same length as the claw ; digitules to claw and tarsi simple. Mentum uniarticulate ; 

 unexpanded filaments reaching nearly to end of body. Pygidium with two large 

 median, almost rectangular lobes ; immediately within these are the two long anal 

 setae, and two very short ones ; the latter arising from a central raised prominence. 

 On either side of the lobes are a varied number of broad, and very finely serrated 

 plates, and several small spines. The median lobes are very distinct, and their bases 

 run almost through the pygidium. Segments each with two elongated pores, one 

 ventral and one dorsal. 



It is entirely through the persistent investigation of the species 

 by Herr Karel Sulc, and his discovery of both the adult ? of this 

 species and Leucaspis pini, Hartig, that I have been able to clear up 

 the identity of the two species. It is unfortunate, however, that I did 

 not in the first instance describe the species as a new one ; but like 

 Mr. Morgan (Z. c.) I was in doubt all along as to whether the peculiar 

 fringe of blunt spines on the pygidium of $ Leucaspis pini, as described 

 by Signoret and Low, were really chitinous or only waxy secretions. 

 Now the doubt no lontifer exists since Herr Sulc has discovered the
