BRACHYGLUTINI 203 



Antennae with ninth segment large, obconical, the length of the seg- 

 ment equalling its apical width at least laevis 



(1.4 mm.; known only from Bolivia) 



Antennae with the ninth segment strongly transverse 2 



2. Known only from Venezuela; male with the fourth tergite transversely 

 and obliquely foveate on each side, and with a median tubercle; 



1.0 mm brevicornis 



Known only from Colombia; male fourth tergite not armed in this 

 manner longipes 



brevicornis Raffray. 1890. Venezuela. 



laevis Raffray. 1904. Bolivia. 



longipes Raffray. 1887. Colombia. Genotype. 



BYTHINOGASTER (Schaufuss, 1887) 



This is a highly specialized monotypic genus, known so far only from 

 Hispaniola (probably Haiti as the citation is "Saint-Domingue") . 



The abdomen is short, convex with an exceptionally narrow margin for the 

 Brachyglutini, and like Globa, presents certain batrisine features. The maxil- 

 lary palpi, however, are very different from those of Globa, the first segment 

 is minute; second segment elongate, arcuate, apically swollen; third segment 

 peculiar, lenticular with the long axis of the segment vertical, that is longer 

 than wide, the external (lateral as opposed to mesial) face is concave and 

 this concavity is supplied with spongy pubescence; fourth large, oval, acumi- 

 nate, bearing a palpal cone. Ventral surface of the head, flat and unsculptured 

 (Raffray, 1908, p. 203) with exception of a median, longitudinal carina (Raf- 

 fray, 1908, key, p. 192). Middle coxae slightly separated. This odd genus is 

 said by Raffray to resemble the Australo-Asiatic genus Eupines. I am un- 

 familiar with either of these genera.
