long extended fasts ; and I believe the late Mr. Maskell was the first 

 to call attention to this peculiar trait in the Coccidoe^ but this species 

 certainly beats all previous records that are known to me. 



Antonina socialis, n. sp. 



Ovisac of 9 usually complete, and wholly or partly hidden beneath the leaf- 

 sheaths of the bamboo ; white, elongate, ovate, flat, and closely felted, but brittle. 



Long., 5 — 8 mm. 



Adult ? (fig. 10) viviparous ; elongate, about 3 times longer than broad ; legs 

 absent. Antennse (fig. 12) comparatively long, of 3 joints, basal joint shortest, 2 and 

 3 of nearly equal length, the latter with 5 — 6 stout hairs at the tip, and a single one 

 on the first, articulations very distinct. Rostrum inserted about one-ninth of the 

 distance between the extremities, raentum uniarticulate, loop of filaments extending 

 midway between the spiracles; 2nd pair of the latter central, 1st pair equidistant 

 between them and the cephalic margin. Anal ring (fig. 11) with 6 hairs lying 

 within a trough-shaped cavity. Dermis above with circular spinnerets, which in- 

 crease in number towards the margins, and on the abdominal segments, those at 

 the posterior extremity becoming gradually larger and more numerous. 



Long., 4"8 mm. 



Larva : antennae of 6 joints, of which 6 is much the longest, formula;, 6 (1, 2, 

 3, 4, 5). Anal lobes well formed and furnished with several spines. Anal ring of 

 6 hairs recessed from the margin. 



This species may be recognised by its comparatively long antennae and the 

 curious flattened hairs. 



Hab. : living in company with the preceding species under the 

 leaf-sheaths of Ariindinnria jcqyonica, under glass, Broxbourne, Herts, 

 on freshly imported plants. Eeceived from the Editor of the Gar- 

 deners' Chronicle, Dr. Masters, January 26th, 1899. 



The following pai'ticulars concerning the form and colour of the 

 insects in life were made when they first reached me. Unfortunately 

 I did not then discover there were two species living together, and. I 

 cannot now eliminate the characters of the respective species with 

 any certainty : — 



" Form :— Distinctly elongate, cephalic portion more or less clypeate, with the 

 margins thin and slightly produced ; convex and slightly widest in the middle. The 

 whole dorsal area presenting a remarkable resemblance to the convex side of a 

 grain of wheat." 



" Colour : — Dirty white, pale to dull ochreous or brownish, abdominal extremity 

 red and brown." 



Dacttlopius Luffi, n. sp. 



Ovisac of 9 rather closely felted, long, cylindrical, and of equal width through- 

 out ; ? remaining, uncovered, at the cephalic extremity. 



Long., 3 — 4 mm. ; diameter, "75 mm.
