Idracowra. The prosternal tubercle is very broad, acuminate and 
very low. Habit of Brachytettix. 
Tpigoniza maculatus, sp. n. The insects placed here provisionally 
resemble the European Pamphagus and North American Brachypeplus to a certain 
extent, but differ from the former by having a promiscuously produced fastigium 
and uncrested pronotum, from the other by their terete pronotum and elongate 
tibife, etc., while sepai’ated from the American Dactylotum by the horizontal or 
scarcely suberect fastigium and multispinose hind tibiae. With Trigoniza it appears 
united by a similar prosternal tubercle, labiform elytra and general habit, but 
differs in the pronotum being without a keel. The following description will serve 
for identification:— 
Body brownish or blackish with nuDietotcs round elevated yelloivish or ivhite 
dots and spots over the whole surface^ except beneath. The male very much smaller 
than the female, else similar. Head small, pale, smooth, except vertex ; fastigium 
much produced, horizontal ( c? ) or raised ( 2 ), disk excavated; face much declined; 
antennie slender, longer than pronotum, flattened, 16 (2) to 18 (J') jointed.
