$ . Frons arcuate rugose ; occiput anteriorly arcuately, 

 posteriorly transversely rugose. Posterior margin of head very 

 finely bordered. Second iiagellar joint one and a half times as 

 long as first, third as long as first and second together. Neck 

 very finely trans-striate ; semiannular entirely smooth. Meso- 

 notum very difl^usely and finely punctate ; scutellum smooth, with 

 a few marginal punctures. Mesopleurte shining smooth above, 

 dift'usely punctate below ; metapleursD irregularly rugose, 

 separated by a narrow but distinct sulcus from the median 

 segment, which is very diflfusely punctate, apically irregularl}' 

 transrugose. Petiole trans-striate, a little shorter than rest of 

 abdomen, with two very distinct lateral tubercles before middle ; 

 remaining segments smooth, apex o£ abdomen dull. Terebra 

 longer than body, sheaths white-banded before apex. Hind coxfe 

 with diffuse scale-like rugosities ; hind femora polished, bidentate; 

 hind tibise compressed to middle.

 centrally. 



Length 18 mm.; terebra 33 mm. 



Habitat: Para, Brazil. Type in British Museum, 



Very similar to mactdipennis Westw., but diff"ers in the almost 

 smooth neck of pronotum, more diffuse puncturation of mesonotum 

 and median segment, trans-striate petiole with much larger

5 S . Frons and vertex arcuate rugose ; occiput regularly, 

 laterally irregularly transrugose. Posterior margin of head 

 simple. Second flagellar joint one and a half times as long as 

 first ; third normal. Neck very coarsely, basally more finely 

 transrugose; semiannular polished smooth. Mesonotum coarsely 

 and diff'usely, laterally more densely and partly confiuently 

 punctate, the median row of punctures and lateral divergent 

 impressions very distinct. Scutellum smooth, with a few con- 

 spicuous marginal punctures. Mesopleurse above shining smooth, 

 below finely and diffusely punctate ; metapleurte coarsely and 

 irregularly rugose, separated by a narrow but distinct sulcus 

 from the median segment, which is coarsely and diff'usely 

 punctate, apicall}^ transrugose. Petiole smooth, basally finely 

 trans-striate, with a small tubercle on each side before the 

 middle, shorter than rest of abdomen, which is subnitidulous, 

 apically dull. Hind coxse with diffuse coarse rugosities, only
