ART. 19 NEW BEETLES OF THE FAMILY CEEAMBYCIDAE FISHER 17 



collected by William M, Mann, with the Mulford Biological Explora- 

 tion in Bolivia during 1921-1922. 



This species is allied to albitarsis Klug and fugws Thomson, but 

 differs from albitarsis in not having the pronotum longitudinally 

 carinate, and from fugax by having the elytra abruptly subulate and 

 strongly dehiscent posteriorlj^ 



TOMOPTERUS VESPOIDES White 



Toniopterus vespoides White, Cat. Col. British Museum, pt. 8, 1855, pp. 

 176-177, pi. 5, fig. 8. 



This interesting little species was described by White from Gua- 

 / temala, and has been collected in numbers by Ferd. Nevermann at 

 Hamburg farm, Costa Rica, during August, 1925, flying like wasps 

 around freshly cut timber, apparently " Sapotaceae," and he has 

 observed a female depositing eggs in a hole in the dry bark. Never- 

 mann writes that the females seem to be very rare, as out of 35 

 examples collected, only two were females. 



The sexes of this species are quite different ; the males have the eyes 

 nearly contiguous in front, and are dull black above, with the an- 

 terior and posterior margins of the pronotum, two spots on the 

 metanotum, last dorsal segment of abdomen, and the posterior mar- 

 gins of the ventral surface of the abdominal segments clothed with 

 golden yellow pubescence. The elytra have the anterior part of the 

 lateral margins and a narrow, oblique vitta on each elytron reddish 

 yellow, the vitta extending from the humerus to middle of elytron at 

 apex. The females have the abdomen more robust, the eyes dis- 

 tinctly separated from each other on the front, the surface sparsely 

 clothed with yellowish pubescence, and in addition to the yellow 

 pubescence mentioned on the males, have the median part of the pro- 

 notum sparsely, and the scutellum densely clothed with golden yellow 

 pubescence. The reddish yellow margins and vittae on the elytra 

 are distinctly broader, and in some examples these unite and the 

 entire lateral half of the elytron is reddish yellow, which is the form 

 figured by White. 



TOMOPTERUS VITTIPENNIS, new species 



Male. — Form similar to qioadratipennis Bates. Above uniformly 

 black, each elytron with the lateral margin and a narrow oblique 

 vitta brownish yellow, the color becoming paler posteriorly, and the 

 vitta extending from the humeral region to apex at middle of ely- 

 tron; beneath brownish black, with the base of posterior femora 

 and the inner surface of posterior femora and posterior tibiae paler. 



Head with the front moderately long, and with a narrow longi- 

 tudinal carina on the occiput; surface finely, densely punctate, and
