HOPLODICTYA new genus 



Similar to Monochaetophora, but the frons has two fronto- 

 orbital bristles, of which the anterior one is proclinate and situated 

 farther from the orbit than the posterior one. The second an- 

 tenna] joint has two stout bristles above; there are three to 

 four dorso-centrals; the prescutellar bristles are absent; sterno- 

 pleura with one bristle. 



Head higher than long, as broad as high. Eyes obliquely 

 ovate, with facial orbits straight. Frons horizontal with two 

 orbitals, in series converging anteriorly; the anterior bristle pro- 

 clinate, the posterior one reclinate. Mesofrontal stripe not evi- 

 dent except as a slightly excavated line. Face vertical, broad, 

 slightly concaved; epistoma slightly prominent. Cheeks broad. 

 Lunule retracted, second antennal joint broad with lateral bare 

 area subopaque; third joint as long as second, deeply concaved 

 above, attenuating to a truncate apex; arista loosely plumose, 

 black. Scutellum broad, flat, with four bristles. IVIeso- and ptero- 

 pleura with few bristles. Fourth abdominal segment of male 

 usually shorter than the third or fifth. 



Genotype. — Tetanocera setosa Coquillett. 



I know of three species belonging here, which may be dis- 

 tinguished as below. They should not be confused with those 

 of Trypetophora, which have both frontal bristles reclinate and 

 a distinct prescutellar pair. 



Femora annulated with brown; abdomen with three stripes spinicornis 



Hind femora with submedian spot alon?; dorsum of abdomen uniformly 



brown with pale lateral margins. (Bermuda species) kincaidi 



Femora entirely immaculate, pale setosa
