BITTACUS. 247 



4. B. punctiger. 



Bittacus punctiger Westw. ! Trans. Ent. Soc. Lond. IV, 195, 2. Walk. 

 Catal. 468, 13. 



Testaceo-fulvous ; femora sparingly clothed with black, bristly 

 hair, tibiae with a slender, apical black ring ; wings yellowish- 

 hyaline, with numerous, rather obscure points, especially at the 

 base of the longitudinal veins, and at the transverse veins ; veins 

 pale. (From the description of Westwood.) 



Alar expanse 42 millim. 



Hah. Georgia. 



5. B. stigmaterus ! 



Bittacus stigmaterus Say, Godman's West. Quart. Report, II, 164. — Bittacus 

 pallidipennis Westw.! Trans. Ent. Soc. Lond. IV, 195, 3. Walk. 

 Catal. 468, 14. 



Fulvo-luteous ; ocelli somewhat surrounded with fuscous ; palpi 

 black ; anterior femora and apex of the tibiae sub-fuscous ; wings 

 luteo-fusco-hyaline, the pterostigma a little obscurer; veins luteous ; 

 superior appendages of the male oblong, long, the apical margin 

 subemarginated above. 



Alar expanse 37 — 46 millim. 



Hah. Missouri, near Fort Osage (Say) ; Maryland (Uhler) ; 

 Dalton, Georgia (Osten Sacken). 



The female from Maryland is smaller, and agrees better with 

 the descriptions and size of B. stigmaterus, and pallidipennis. 

 The male from Georgia is larger (46 millim.), the wings are also 

 broader, but it is hardly different. 



6. B. occidentis. 



Bittacus occidentis Walk.! Catal. 469, 16. 



Testaceous ; apex of the rostrum, the palpi, and the antennae 

 black ; dorsal middle of the thorax fuscous ; posterior femora ful- 

 vous, with the apex black, the anterior femora black, with the base 

 fulvous ; anterior tibiae piceous ; wings sublurid, pterostigma fus- 

 cous ; veins black. (From the description of Walker.) 



Alar expanse 46 millim. 



Hah. Erie, Pennsylvania. 



It is very much like the preceding species. Is it distinct from 

 it?
