101. GENUS CLEPSYDRIUS FOWLER 



Clepsydrius Fowler, B. C. A. II : 95 (1895). 



Chapacters : This genus is very closely related to Xolania from which it differs chiefly in the 

 absence of suprahumeral horns. The type species. which is the only species known, is a small brown 

 and yellow insect with a very bulbous pronotum and a trispinose and bulbous posterior process very 

 similar to that seen in the two preceding genera. Head subquadrate, wider than long; base straight ; 

 eyes globular; ocelli large, prominent, equidistant from each other and from the eyes and situated on a 

 line drawn through centers of eyes; inferior margins of genas broadly rounded; clypeus exlending for at 

 least half its length below inferior margins of gense. Pronotum bulbous and spinose; no suprahumeral 

 horns ; humeral angles weak and rounded ; metopidium sloi)ing with the sides bluntly angular at the top ; 

 a distinct transverse groove across the metopidium above the humeral angles; median carina very faint; 

 anterior portion of pronotum convex; sides of pronotum deeply impressed above the lateral margiiis so 

 as to form a dorsal swelling above; posterior process broadly swoUen at base into a bulbous lobe from 

 which project three short, sharp, posterior spines. Tegmina entirely free; corium fully exposed ; cells 

 large and irregular in shape; veins prominent; five apical and three discoidal cells; median apical cell 

 petiolate; iirst apical cell extending far along thecostal margin; apical limbus broad and wrinkled. Hind 

 wings withfourapical celis, the second cell stylate. Legssimple; hind legs extremely long in proportion 

 to the others and the hind tarsi about twice as long as those of the other legs. 



Type conslrictus Fowler. 



Geographical distribution ; Known only from the type species which, however, seems to be 

 quite common in many parts of Mexico.

102. genus paranton>e fowler 



Parantonae Fowler, B. C. A. II : loi (1895). 



Characters : This is indeed a very strange-Iooking genus, as Fowler has remarked, and while 

 it bears a superficial resemblance to Antona:, a fact which doubtless suggested the generic name to its 

 author, it differs from that genus in many important characters. The most distinctive features are the 

 peculiar hood-shaped anterior pronotum and the deep constriction across the middle of the dorsum sepa- 

 rating this anteiior swelling from the strongly bulbous base of the posterior process. The head is sub-
