1 20 Mr. A. Hempel on Brazilian Coccidse. 



Length of joints: (1) 31, (2) 45, (3) 45, (4) 40, (5) 45, 

 (t>) 45, (7) 25, (8) 22. All of the joints except joints 3 and 4 

 bear hairs. Rostrum large ; rostral loop long. Legs present 

 as short cylindrical tubercles terminating in a long claw. 

 Spiracles small, close together, with a few round spinnerets 

 about the orifice. Anal ring apparently with ten hairs. 

 Just behind the anal ring there is a chitinous plate with a 

 deep notch in the middle. The abdomen ends in two incon- 

 spicuous tubercles, each bearing a terminal seta and a few 

 short spines. Around the lateral margin there are a ^ew 

 short, sharp, spine-like liairs. On each side of the cephalic 

 region on the dorsal surface there is a group of two large 

 spines, one longer than the other; behind these there is 

 another Sj)ine, and behind the second one another, so that we 

 have two longitudinal rows of four s))ines each. These 

 spines are large, slightly curved, with the ends rounded and 

 slightly expanded, and are from 53 to 66 /a long. The entire 

 surface of the body is thickly set with small V-shaped spin- 

 nerets and numerous fine filamentous glands about 44 jj, long. 



Male scale cream-coloured, elliptical, rounded at both ends; 

 transversely wrinkled, and with a longitudinal median ridge 

 and a slight groove around the dorsum near the lateral 

 margin. Length 1*50 millim, ; width '50 millim, 



hah. Ypirauga, State of S. Paulo. Thickly covering the 

 trunk and branches of an unidentified forest-tree. 



Should this insect attack cultivated trees, it would do much 

 harm by its great numbers. 



This species has a superficial resemblance to L. celtidiSj 

 Ckll., but can be readily distinguished by the segments of 

 the antenna, the absence of functional legs, and the presence 

 of spinnerets and filamentous glands. 



Subfamily Tacrabdiinje. 

 Genus Tachardia, Blanch. 

 Tachardia cydonice^ Hempel. 



Adult female scale dark coffee-brown, smooth, shiny, 

 slightly elongated, with three processes or rays on each side. 

 Dorsum not very convex, with a slight hump in the middle, 

 behind which is an opening with the lac slightly raised 

 around it. Lac not brittle. 



Length 3*75 millim.; width 2-50 millim.; height 1'50 

 millim. 



Adult female boiled in a solution of KOH colours the 

 liquid a deep red. The insect is slightly longer than wide
