Acrotelsa splendens sp. iiov. (Plate XVi, hgs. 1-10.) 
Spccilie Diagnosis . — Body elon^nte, dorso-ventrally eonipresso 
antei iovly ; suheyliiidrieal i)osteriorly ; thorax searcely -wider tlu- 
the abdomen. Head prominent, well marked off from the body ai 
beariii.!^’ anteiiorly two very eons])ieuous tufts of setae, the lar^ 
biaid^ eyes posteriorly situated. Tergite ten sharply terminate- 
the eonvergino- edges eoueave outwards and with groups of seta 
arranged alternat(‘ly on eaeli side. The entire body, iiududing th 
legs, covcu-ed with scales. Antennae about as long as the bod; 
Median ;uial cerci as long as the abdoineii. Metasternite sull 
triangular in shape, with two closely a])]U‘oximated rows of seta 
one each side of the a])ex. Mesosternite snialhug more ])oiiited, am 
with two rows of setae on each lateral margin. Ovipositor withoii 
small tul)('rculate s])ines at its ai>ex. 
('ohiur (in S])irit) y(*llow with a dense cov(‘ring of reddis? 
l)rowu and black scales. 
Length: male 0 mm.; female 7 mm.

Jtetailcd Description. — The Body (PL XVI, fig. 1) is distinctl;, 
more ffatteiied in the thoracic' region than in the abdominal, tlr 
thoracic tergites being laterally less closely adherent to the body- 
making it approximately as wide as the abdomen. The entir*- 
surface is covered Avith scales, Avhich appear mudi denser in tin. 
lateral regions tlian dorsally, owing ])robably to their being shea 
from the central ])ortion of the segment.al plates. 
The head is semicircular in outline anteriorly, the eyes se' 
w(dl back from the origin of the antennae. The cephalic setae ara 
stout, pectinate and radially arranged, AA'hilst the mandibular setau 
project far beyond the outline of the head. The iiitersegnieiita 
neck iH'gioi] is well defined, giving the head a detached a])pearance. 
Tlic i>roihorax is about half as long as broad, the posterior 
margin of the tergite being excaA’ated by a deep, almost semi- 
circular notch. Tile lateral margins are fringed Avith stout, jiectinate" 
setae, and the jiosterior margin has tAVo symmetrical comlis of. 
similar l)ristles. 
The inesothoraeie tergite is the largest, its ])OSterior margini 
not being excavated but rather couatx, and carries tAvo combs ofi 
setae similar to those upon the preceding segment. The laterall 
margins aie sidose, l)ut less conspicuously so.
