ants. L. formicarum, Newst., at the period of gesta- 

 tion, envelopes herself in a loose cottony sac, while 

 L. brevicornis, Newst., covers her body with a thin talc- 

 like secretion. But neither L. rhizophila, T.T., nor 

 L. lineolatde, Ckll., is known to make a secretionary 

 covering; it is highly probable, however, that both 

 species will be found to form an ovisac of some kind, 

 unless they protect their ova in the same way as 

 Lecanium, which is very unlikely, considering the 

 nature of the habitat.

LECANOPSIS BREVICORNIS (Newstead). 

 (PI. XXXIX, figs. 1-5.) 



Lecanopsis brevicornis, Newstead ; Ent. Mo. Mag., 

 s.s., vol. vii, p. 59, figs. 1-3, 1896. 



Adult female (figs. 1, la, and 2) bright red or 

 reddish crimson ; ovate, narrowed in front, convex 

 above, flat beneath ; dermis in life very firm and highly 

 chitinised, more especially so at the margins ; segmen- 

 tation clearly defined. Antennae (fig. 3) black at the 

 tip, extremely short, tapering, and composed of six, 

 and sometimes apparently of seven joints, but the 

 apparent additional joint is due to a constriction which 

 simulates a joint ; the width of the first nearly equals 

 the length of the remaining five joints, and each joint 

 is successively shorter and narrower than the preceding; 

 there is a single hair on the second and fifth joint, and 

 there are several on the sixth. Legs (figs. 4, 4 a) very 

 short, black, shining, tapering, and atrophied; coxa
