doing more than gathering nectar from the nectaries of the squares 

 and was not noticed when these were placed in the rearing cage. 

 It is more likely that it breeds in the fruit of a leguminous or cario- 

 phyllaceous plant. 



Family OROBITID^. 



Subfamily OROBITIN^. 



Tribe TYLODINI. 



Genus GASTEROCERCODES, new genus. 



Rostrum moderately long, reaching mesocoxae, widest at base, narrowest at middle; 

 scrobes beginning slightly beyond middle, directed at lower half of eyes. Eyes large, 

 elliptical, coarsely granulated, narrowly rounded above, separated by a distance less 

 than the width of the beak at its narrowest point, reaching lower edge of beak and acu- 

 minate beneath; partly covered by postocular lobe when in repose. Antennal scape 

 reaching eyes; funicle 7-jointed, the first four joints longer than broad, the first longest, 

 each succeeding joint shorter than the preceding, but at the same time becoming 

 gradually wider from second to seventh; club oval, 1-jointed. Scutellum minute. 

 Prothorax truncate at apex above, with lateral lobes not very conspicuous; base 

 bisinuate, angulately produced at middle; sides almost parallel to middle, thence 

 strongly narrowed to apex, widest just in front of middle; surface deeply pitted, 

 sparsely squamose. Elytra wider than thorax, humeri obtuse; striae impressed, 

 punctate, 10-striate, the tenth strise reaching only as far. as the metacoxse; pubescence 

 sparse. Pectoral canal deep, ending in a nestlike pocket of the mesosternum, which 

 is short; metasternum extending forward between the mesocoxae; metepisternum 

 distinct and moderately wide. Intercoxal process of abdomen broad, subogival; 

 abdominal sutures straight; the three middle segments subequal. Femora canalicu- 

 late beneath, mutic; tibiae unguiculate; tarsal claws simple. 



This genus is nearly allied to Gasterocercus, Homoeostetlius, Metri- 

 opJiilus, and Bothrohatys, but differs from all in several respects. 



Under high power microscopes the club does not show any indica- 

 cations of sutures.

Described from nine specimens from cotton stalks collected by Mr. 

 C. II. T. Townsend at Piura, Peru, and bearing the number ^^9." 



Length, 3.2 mm.; breadth, l.G mm. 



Color of integument varying in individuals from reddish to dark piceous; club 

 lighter reddish or yellow; pubescence sparse, consisting of elongate pale setiform 

 scales, giving a bristling appearance. Head rounded, coarsely deeply punctured, 

 with intermediate surface minutely granulate, punctures bearing each a tiny seta. 

 Median line of head and beak continuous; beak moderately arcuate, coarsely rugosely 

 punctate, sulcate with smooth median line, much coarser in male than female; the 

 elongate scales border the upper edge of the eye and extend the length of the beak, 

 arising from the punctures. The eyes are depressed, very coarsely granulate, black, 

 only half concealed by the postocular lobe of the prothorax. Antennae with very 

 few fine hairs on funicle, scape glabrous, club densely pubescent, minutely punctate.
