i68 HOMOPTERA 



tum and with enormously long hind legs. Head subquadrate, twice as broad as high; base elevated, 

 thin, sinuate, margin depressed in middle; eyes globular, slightly flattened laterally ; ocelh large, con- 

 spicuous, somewhat elevated, twice as far from each other as from the eyes and situated about on a line 

 drawn thro.ugh centers of eyes; inferior margins of genas straight; clypeus broad, flattened, subfolia- 

 ceous, extending for three-fourths its length below inferior margins of genas. Pronotum convex, without 

 processes of anykind; metopidium sloping, broader than high ; no median carina; humeral angles 

 obtuse, rounded ; posterior half of scutellum elevated into a high, erect, laterally flattened horn which is 

 more than twice as high as broad, with thin flattened anterior and posterior margins. Tegmina hyahne 

 with strong veins; tips broadly rounded; interior claval area coriaceous and punctate ; five apical and 

 two discoidal cells ; no apical Hmbus. Legs simple, very slender; hind legs at least tvvice as long as 

 either of the other pairs; femora cyhndrical, tibiae angular in cross section; hind tarsi much the longest.

148. GENUS LAMPROPTERA Germar 



Lamproptepa Germar, Rev. Silb. III : 261 (i835). 



Chapacteps : This genus represents a division of the Abelini in which the insects have a single 

 horn on the pronotum, and Lamproptera is particularly distinguished by having not only a long sharp 

 horn on the pronotal disc but another on the scutellum. Head with clypeus triangular; base highly 

 elevated, bituberculate, weakly sulcate between the two lobes; eyes small and globular; ocelli small, 

 inconspicuous, more than twice as far from each other as from the eyes and situated high up on the 

 head, about on a Hne drawn through the upper margins of the eyes; inferior margins of genae sloping 

 and sinuate; clypeus very large, broad, flattened, extending for three-fourths its length below the inferior 

 margins of the gense, tip long and triangular, giving the face a distinctly triangular outline. Pronotum 

 convex and bearing a single, long, erect, sharp, laterally flattened dorsal horn which is twice as high 

 as its width at the base and has the anterior and posterior margins thin and sharp; metopidium vertical, 

 broader than high; median carina percurrent ; humeral angles weak and rounded; scutellum entirely 

 exposed and bearing a sharp erect dorsal horn, almost exactly the same in shape and general appearance 

 as that on the pronotum but considerably longer. Tegmina entirely free; hyaline with strong, colored 

 veins; very broad; base narrowly coriaceous and punctate; tips broadh' rounded; five apical and two 

 discoidal cells; no apical limbus. Legs simple and very slender; femora cylindrical, tibiae triquerate; 

 hind legs very much longer than the others and hind tarsi more than twice as long as either of the 

 other two pairs. 



Type capreolus Gerniar. 



Geogpaphicai distpibution : This genus is known only from South America and in the case 



of the three Fabrician species the particular locahties are not recorded.
