Boiled in a solution of KOlI it colours tlie liquid deep pink. 

 The antennae aro short and nearly of equal thickness through- 

 out. The lac-glands arc large and very near the large 

 spiracles. Around the opening of the large spiraehis and 

 between tliesc and tiie other s|)iraeles are many spinnerets. 

 Rostrum and mentum large ; rostral loop short. The legs 

 are represented by inconspicuous short, sharp tubercles. On 

 the ventral surface in front of the antennaj there are two 

 groups of about sixteen elongate glands each, and behind the 

 antenna? there are two more groups of from eight to ten 

 fjlands each. The dorsal horn is '146 millim. long, sliarp, 

 with two small tubercles at the base. The anal ring bears 

 ten long sharp hairs, which protrude almost their entire length 

 beyond the chitinous collar or caudal ring, and flare outwards. 

 The caudal ring is large and bears many minute tubercles 

 and a few hairs at the base. This ring terminates in ten short 

 chitinous plates, whieh have nearly parallel sides and the ends 

 deeply and irregularly incised. The four tubercles on the 

 dorsal surface between the caudal ring and dorsal horn are 

 small, but bear from forty to tifty round spinnerets each. 

 The entire surface of the body is covered with small tubercles, 

 each one terminating in a hair. Tiie ventral surface has 

 the appearance of bearing many transverse rows of minute 

 hairs. 



Hab. Cachoeira and Ypirauga, State of S. Paulo. On 

 twigs of a bush of the order Myrtaceai. 



Many of the insects are covered with a black fungus. The 

 individuals are usually distinct, the lac seldom fusing. 



Tachardia rosoij Herapel. 



Female test elongate, deep orange-red in colour, with a 

 hump on the dorsum and three processes on each side radiating 

 from the lateral margin, giving it a star-shaped appearance. 

 There are usually two fine filaments of white secretion in 

 front of the dorsal hump, ])robably arising from the large 

 spiracles. Many of the individuals are distinct, with soft 

 plastic lac, but in the older specimens the lac is hard and 

 brittle and usually fused into larger masses. 



Average size : — Length 4 millim. ; width ."5 millim. ; height 

 1*75 millim. 



The adult female, denuded of wax, has tiirec small tubercles 

 on each side, lioiled in a solution of K(JiI it colours tiie 

 liquid a deep red claret-colour. Anteimaj small, club-shaped, 

 with two or three short hairs on the last joint. The joints 

 are confused and indistinct, but appear to be four. Lcn^-th
