165. GENUS SMERDALEA Fowler 



Smerdalea Fowler, B. C. A. II : 162 (1896). 



Characters : This genus is known only from the type species which is a large, rough. spinose 

 insect characterized especially by the heavy, irregularly branched suprahumeral horns and the trispinose 

 posterior process. Fowler's specific name is well chosen — it is a horrible looking insect. Head sub- 

 triangular, very roughly sculptured, inferior margin trilobed ; base feebly sinuate with a nodular protu- 

 berance on each side of the median hne; eyes large, protruding, ovate; ocelli large, prominent, equidis- 

 tant from each other and from the eyes and situated low on the face about on a line drawn through lower 

 margins of eyes; inferior margins of gense produced downward into short rounded lobes; clypeus very 

 large, extending for half its length below the inferior margins of the genas. Pronotum convex, bearing 

 a pair of large, heavy, irregularly toothed suprahumeral horns and a long, rough, nodulate and spinose 

 posterior process ; metopidium sloping, broader than high; median carina percurrent; humeral angles 

 large, triangular with spine-hke tip; suprahumerals heavy, twice as long as the distance between their 

 bases, extending outward and upward, decorated with an irregular series of long spine-Uke teeth ; poster- 

 ior process robust, rough, with a node at the base and a large apical swelling which is dentate above and 

 ends in three heavyspines, extending as far backward as the internal angles of the tegmina; scuteUum 

 entirely exposed, long, heavy, swoUen at base and with a dorsal node before the apex which is tectiform 

 and then suddenly acuminate. Tegmina opaque, coriaceous and punctate on basal half. hyahne on 

 apical half; veins heavy and usualiy pubescent; five apical ceUs; one discoidal ceU ; apex roundly 

 truncate; no apical limbus. Legs simple, cyUndrical; aU tarsi about equal in length.

Characters : Large. rough insects with heavy suprahumeral horns and an elevated toothed 

 nodeon the posterior process. Head subquadrate, broader than high, very roughly sculptured ; base 

 high and sinuate and bearing a very large conical tubercle on each side of the median Une ; eyes ovate ; 

 oceUi large, conspicuous, equidistant from each other and from the eyes and situated on a Une drawn 

 through centers of eyes; inferior margins of genag extended forward in rounded lobes; clypeus large, flat, 

 extended for three-fourths its length below the inferior margins of the genae. Pronotum rough, 

 convex, with large, triquerate, toothed suprahumeral horns, extending outward and upward and 

 somewhat longer than the distance between their bases ; metopidium vertical, broader than high; 

 median carina percurrent; humeral angles large, robust, triangular, blunt; posterior process heavy, 

 sinuate, with a high toothed lobe at the base and with the tip flattened and blunt and reaching just to 

 the internal angles of the tegmina: scutellum well exposed, subtriangular, roughly ridged. tip notched.
