segment is an outwardly extending foliaceous lobe, nearly one- 

 third the width of the segment on two to five, very small on one and 

 broadened extremely on six, to a broad mucronate lamellar expan- 

 sion 4 mm. from tip to tip. Between the lobes on the connexival 

 edge are three to four short stout spines and the posterior edges 

 of the last expansion are serrate. The smaller lobes are irregular 

 in outline, longer than broad and with two or three points on each. 

 Abdominal segments one and two keeled, three evanescently so. 

 Third pair of legs longest, simple, femora setose, tibiae with a few 

 short, black spines exteriorly, longer than femora. Second pair 

 longer than the first ; femora with a single row of spines above, and 

 two beneath, tibiae with an external row of small black spines ; first 

 pair shortest, femora and tibiae equal, femora much stouter than in 

 the others, armed with one row of strong spines beneath and one 

 above, tibiae simple, as the others. 



Dimensions: Head, long. 2.3 mm.; lat. 1.9 mm., including 

 eyes. Prothorax, long. 3.5 mm. ; lat. ant., .8 mm., post. 3 mm. 

 Scutellum, long. 1.2 mm., lat. i mm. Abdomen, long., including 

 lobes, 1.3 mm. ; lat. 3 mm. at widest part, 4.4 mm. at lobes. Total 

 length, 18.8 mm., greatest width, 3 mm. 



Described from one J^ from the same locality and collector. . 



Eurylochus* gen. nov. 



Head short, not produced beyond eyes, which are large and 

 prominently rounded and occupy nearly the whole head seen from 

 the side. Antennae moderately long, first joint stoutest and 

 curved, third and fourth filiform. Pronotum tumid, narrowing 

 anteriorly, with an irregular process at the anterior angles branch- 

 ing outward. Scutellum spined. Abdomen wider than hemelytra 

 and somewhat hollowed, beneath keeled. Legs simple. Prester- 

 num excavate and enclosed by two lamellar processes. 



This genus is near Veseris Stal, from which it differs by absence 

 of spongy fossae on the anterior tibiae, by the long second joint of 

 the antennae and by the lateral processes to the excavate pro- 

 sternum. 



Type: Eurylochus bellator Bueno. 



Distribution : British Guiana. 



* The only one of the companions of Ulysses that withstood Circe's 

 magic cup.
