nae, mandibles except tips ami scape underneath, yellow. Flagelhini 

 pieeous, ferruginous underneath towards base. 



Seutel with but few of the larger puni-tures. Mesopleura bordered in 

 front by a foveolated groove. The furrow betwecp. luefio and meta- 

 pleurae replaced by a liroad shallow depresson but medially with 

 a long narrow deep groove whi-'h is slightly bent lielow. Postseutel 

 longitudinally rugoso-punctate. Upper area of metanotum with about 

 fourteen sharp carinae, the bounding groove wanting. The posterior 

 fa&e has very large pnnotures above and at sides, broadly depressed 

 at middle below, the m^edia.n groove replaced by a carina, the central 

 fovea irregular, the surface below transversely rugose. The yellow 

 markings of the thorax are a broad band on pronotiini ,the tubercles, a 

 long mark below teguhte, the seutel, and a dot within tegulae. The 

 tegulae are ferruginous. 



Abdominal tergitos with a]vical yellow bands, broad on I and TT, 

 narrow on TIT, IV, and V, the first somewhat emai-ginate. All of the 

 segments are basally impunetate, the second ventral and the fifth anl 

 sixth dorsals more coarsely punctate. The pygidium medially carinate 

 towards apex. 



Legs reddish yellow, th^e coxae and anterior trochanters partly piceous. 

 Tibiae with very few weak spines outwardly. 



Wings hyaline, smoky from (and including) the first disc(fidal to 

 the marginal cells, the veins and stigma equally dark. Second cubital 

 cell shorter than the third on the cubital nervure. The third abscissa 

 of radius longer than the first and second together.

.^060 Tiphla belizensis sp. nov. 



Black, shining, densely covered with long white pubescence, the Ciil- 

 caria and tarsal spines white; wings clear hyaline, the nervures and 

 stigma black; apex of radius broadly ro\uidly curved, its basal abscissa 

 straight, oblique, about one fourth shorter than the second, the apex 

 distinctly projecting beyond the second transverse cubital nervure 

 which is broadly rounded, slightly sloped towards the CTibitus and about 

 twice the length of the second; the second recurrent nervure is received 

 shortly beyond the middle, in front being roundly curved to shortly 

 beyond the middle, the posterior shorter part is straight and has a 

 much more oblique slope. Clype.is strongly punctured except at the
