distances upon the concave, and probably under, surface of the 

 pod along its outer margin. The exit holes are oval in shape, 

 about two-thirds as broad as long, and present such a great varia 

 tion in size that we may expect to find a nearly similar variation 

 in the beetle. The smallest exit hole measures 5mm. in length ; 

 the largest is double that size. It should be mentioned in pass 

 ing that a Bruchus of unknown identity breeds in the seeds of 

 the same plant. 



The species agrees in all essential characters with the genus 

 Baryssinus of Bates,* differing from the genus Lepturgusf of the 

 same author in the ciliate antennas, and with centrobasal carina 

 on the elytra. As the species has very evidently not hitherto 

 been described, the following specific description is appended : 



BARYSSINUS LEGUMINICOLA Linell n. sp. 



Body broad, ferruginous, densely covered with fine sericeous cinereous 

 pubescence. Antennae twice as long as body, sparsely ciliate beneath, 

 joints 3 to ii paler at base, infuscate at apex. Front quadrangular. 

 Thorax Avith lateral spines slightly behind middle, strong, very acute; 

 sides rounded and convergent in front of the spines, strongly constricted 

 behind them ; discs uneven, but without any distinct callosities, maculate 

 with light brown and golden pubescence and two larger dark brown spots 

 anteriorly; a line of coarse black punctures alo'ng the basal constriction, 

 along the apical margin, around the tubercles, and a few scattered ones on 

 the disc each side of the median line. Scutellum large, truncate at apex. 

 Elytra broad, sides straightly convergent from the base, rounded at apical 

 fourth, apices truncate with sutural angles rounded, external angles sub- 

 acute; disc with a broad semicircular depression before middle, maculate 

 with smaller and larger brownish black spots, and some golden spots, 

 mostly collected in a strongly angular, transverse fascia across the middle ; 

 centrobasal ridges distinct, crested with black hairs; punctures muricate 

 at base, coarser and denser on the flattened surface behind the crests and 

 humeri and gradually finer and obsolete towards apex. Ventral surface 

 uniform in color. Last dorsal segment slightly produced beyond elytra, 

 emarginate at apex (9)- Legs brown, annulated with pale ferruginous on 

 base of femora, middle of tibiae and base of metatarsus. 



Dimensions. Length 8.5 mm. Width 3.5 mm. 



Habitat. Paraguay. Described from a single example, prob- 

 .ably female, taken at the Columbian Exposition in Novem 

 ber, 1893. Type No. 1025 in the U. S. Nat. Museum collection.
