ACORDULOCERIDEA, new genus 



Type. — Acorduloceridea compressicornis Rohwer. 



Belongs to Acordulocerini and may easily be separated from 

 Acordulocera Say by the number of antennal joints; sharply defined, 

 elongate prescutum ; and longer mesonotum. In Konow's tribe 

 Lobocerotides it would seem to run nearest to Lycosceles Konow but 

 will not agree with the description of that genus, being readily dis- 

 tinguished by the presence of a superapical spur. 



Clypeus truncate ; malar space wanting ; eyes very large, slightly 

 converging to the clypeus ; posterior orbits nearly wanting, lateral 

 ocelli well below the supraorbital line ; antennas hairy, inserted well 

 above the clypeus, seven- jointed, scape elongate, pedicellum much 

 wider than long, flagellum long, tapering ; prescutum sharply defined, 

 remote from the anterior margin of the scutellum, more than twice 

 as long as the anterior width, with a median sulcus, mesoscutum and 

 prescutum combined about twice as long as broad ; thorax otherwise 

 similar to Acordulocera; legs rather long; calcaria long; four 

 posterior tibiae with (one each) superapical spurs; tarsal claws sim- 

 ple; hind basitarsis slightly shorter than the following joints; fore 

 radial cell not appendiculate ; anal vein simple ; transverse median 

 vein near basal third ; all the transverse cubits nearly completely bul- 

 lated, the first nearly interstitial with the first recurrent; first two 

 cubital cells large, subequal in length, the second receiving both re- 

 current veins ; third cubital cell very small ; radial cell of hind wings 

 closed and appendiculated on the lower margin ; otherwise the vena- 

 tion is very like Acordulocera. 



ACORDULOCERIDEA COMPRESSICORNIS, new species 



Male. — Length 3.5 mm. Supraclypeal foveae very broad, shallow, 

 not confluent with the antennal fovese ; supraclypeal area gently con- 

 vex ; antennal foveae large ; frontal carnia prominent ; frontal crest 

 angled below ; middle fovea, ocellar basin, postocellar furrow, ob- 

 solete ; antennal furrows only indicated by shallow depressions ; 

 postocellar line longer than the ocellocular ; postocellar area not de- 

 fined ; antennae nearly as long as the rest of the insect, compressed,
