36 GRASSHOPPERS IN GENERAL. 



Thorax. The thorax is striped as is usual in Sarcophagy. The 

 stripes are very distinct in the male, and quite faint in the female. 

 The chsetotaxy of the thorax is alike in the 

 two sexes, and is indicated in the accompany- 

 ing diagram. The female has a smaller num- 

 ber of minute bristles than the male, and 

 consequently its chsetotaxy is more easily 

 FIG. 9. made out. In the diagram I have indicated 



three posthumeral bristles. The two smaller 



ones are in but one specimen large enough to be distinguished from 

 the other hairs or microchaetae. This variation of the posthumerals is 

 common in Sarcophagce. 



Abdomen. The macrochsetse of the abdomen are marginal only. 

 Each segment has a complete row. On the first and second segments 

 they are all of insignificant size, except two or three at the lateral 

 border. On the third segment all are of good size and they number 

 twelve to fourteen. On the fourth segment all are of good size and 

 they number fourteen to sixteen. 



The bristles of the legs are arranged as is usual in Sarcophagce. I 

 can make out nothing worthy of special notice here. 



Wing. First longitudinal vein not spinose. Third vein not spinose 

 for two-thirds to three-quarters of the distance to the small cross- 

 vein. Elbow of fourth almost exactly rectangular and provided with 

 an apparent appendix, which, however, is not a stump of a vein but 

 a slight fold or wrinkle of the wing. Hind cross-vein sinuous, longer 

 than, but hardly twice as long as, that segment of the fourth vein be- 

 tween it and the elbow. Hind cross-vein and apical cross- vein almost 

 exactly parallel. 



This species belongs to Brauer's subgenus Tephromyia of Sarco- 

 phaga ( sens, lat.) In this subgenus the vibrissal angles are distinctly 

 above the mouth edge and, projecting somewhat mesad, distinctly 

 narrow the clypeus. The abdomen does not have the changeable 

 spots, maculae spuriae, of Sarcophaga, but is either unicolorous or 

 marked with fixed spots or lines. The European species of this 

 group are T. grisea Meig., T. lineata Fall, T. qffinis Fall, and T. 

 obsoleta Fall. As far as I am aware hunteri is the first Tephromyia 

 to be observed outside of Europe. Through the kindness of Herr 

 Paul Stein, of Genthin, Germany, I have now in my possession 

 specimens of grisea, affinis and obsolete. From these specimens and 

 the accessible descriptions of lineata, I am able to construct the fol- 

 lowing table for separating the species of this group.
