184. GENUS QUADRINARIA GODING 



Quadrinarla Goding, Journ. N. Y. Ent. Soc. XXXV : 2. 167 (1927). 



Characters : This genus is unknown to iis and vve are including it entirely on the authority 

 of its author. Goding, however, does not figure the type species and consequentiy we are unable to 

 present a Plate Figure. Goding states that the genus is near Brachycentrutus and Gargara, difTering 

 from the former in the shape of the head, the position of the ocelli, dorsum not depressed, acute apex 

 passing beyond apex of clavus, forked radial and simple ulnar veins, sessile exterior and interior 

 discoidal cells and but four apical cells ; and differing from the latter in the subopaque tegmina, three 

 discoidal and four apical cells. The original description is as follows : 



« Head with eyes broad as width between humerals, triangular, base straight not sinuate; 

 eyes small; clypeus not extended below lorae; ocelli even with center of eyes, same distance from 

 each other and base of the head. Pronotum convex, unarmed, with a median carina lightly 

 sinuate at middle of dorsum, densely punctured anteriorly more sparingly behind middle. dis- 

 tinctly notched behind humerals exposing a little of sides of scutellum, and covered with fine pale 

 hairs; posterior process robust, not tectiform, apical fourth acuminate from above and laterally 

 to acute apex which reaches tips of tegmina. Tegmina nearly f ree ; clavus partly covered by 

 sides of pronotum, clear hyaline excepting coriaceous base, sides nearly parallel, apex obtusely 

 rounded, destitute of a longitudinal vein; corium emitting two longitudinal veins from base, 

 radial vein forked at middle enclosing first exterior discoidal cell, ulnar vein simple; three 

 discoidal cells the first exterior cell stylate, second cell behind it sessile base truncate, the third or 

 interior cell equal and contiguous to the others in length, situate between radial and ulnar veins, 

 sessile, its base truncate at a transverse venule; four sessile apical cells bases truncate. Wings 

 with three apical cells, first and second sessile bases truncate, third stylate, second cell large and 

 nearly semicircular, the others sniall. Legs strong, tibiae slender not dilated, tarsi equal. » 



Type u-flava Goding. 



Geographical dlstribution ; The type species from Jamaica is the only known representative 

 of the genus.

185. GenuS MARSHALLELLA GODING 



Marshallella Goding, Journ. N. Y. Ent. Soc, XXXV : 2. 168 (1927). 



Characters : This genus, as judged by the type species. is very distinct and differs from its 

 nearest relatives in having the scutellum entirely concealed and in having the exterior discoidal cell of 

 the corium sessile and truncate at the base. The type species is a large brightly colored insect without 

 suprahumerals, with a long straight posterior process and with the legs and a spot at the base of the 

 tegmina brilliant red. Head subquadrate, roughly sculptured, twice as broad as high; base weakly 

 arcuate and sinuate with a small tuberosity above each ocellus; eyes very large, globular and protruding; 

 ocelli very large, prominent, a little farther from each other than from the eyes and situated slightly 

 above a line drawn through centers of eyes; inferior margins of genae sinuate; clypeus extending for 

 two-thirds its length below inferior margins of genae, tip pointed and pilose. Pronotum low, convex, 

 broad, without suprahumerals; metopidium sloping, twice as broad as high; median carina faintly and 

 irregularly percurrent; humeral angles large, broad and rounded; posterior process long, straight.
