i6o HOMOPTERA 



doisum straight; metopidium sloping, wider than high ; median caiina obsolete; humeral angles weak 

 and rounded; sides of pronotum punctate but not ridged, distinctly impressed behind humerals; 

 posterior process slender, subtriangular in section. very acute, extending beyond the abdomen and 

 beyond the internal angles of the tegmina but not reaching the tips of the tegmina. Tegmina entirely 

 exposed; hyahne ; veins strong, curved and irregular; base, especially the claval area, distinctly 

 coriaceous and punctate; five apical and two discoidal cells; apical limbus broad. Legs simple, 

 subcylindrical; hind tarsi much longer than either of the other two pairs. 



Type personata Sial. 



Geogpaphical distribution ; This genus seems to have about the same range as Thrasymedes 

 being found in Mexico, Central America and South America but not reported from the United States.

138. genus MICRUTALIS FOWLER 



Micrutalis Fowler, B. C. A. H : 116 (iSgS). 



Characters : Small inconspicuous insects with subtriangular bodies, free tegmina with indis- 

 tinct venation but showing four apical cells in the corium. The genus has often been confused with 

 Acutalis and the synonymy of some of the species of both genera is still somewhat in doubt, but the 

 smaller size, very indistinct venation, and the four apical cells of the tegmina should be sufficient to 

 enable Micrutalis to be distinguished. 



Head subquadrate, smooth, convex, twice as broad as high; base feebly sinuate; eyes globular; 

 ocelli small, inconspicuous, farther from each other than from the eyes and situated well above a Hne 

 drawn through centers of eyes; inferior margins of genae rounded ; clypeus extending for half its length 

 below inferior margins of genae. Pronotum low, roundly flattened, triangular as seen from above; no 

 dorsal processes of any kind; metopidium sloping, wider than high; no median carina; humeral angles 

 weak and rounded; sides of pronotum punctate but not carinate ; posterior process flattened, gradually 

 acute, reachingjust about to the internal angles of the tegmina. Tegmina entirely exposed; hyahne or 

 semiopaque; veins indistinct; four apical cells; no discoidal cell; apical limbus broad. Hind wings 

 with three apical cells, the median apical cell truncate at the base. Legs simple, subcylindrical ; all 

 taisi about equal in length. 



Type ephippium Burmeister. 



Geographical distribution : Micrutalis is a large genus with its species widely distributed over 

 the entire New World as is indicated by the following list :
