21. Orphulella costaricensis, sp. n. 



A rather robust insect of variable colour, with the antennae of tbe d 1 scarcely so long as the bead and pronotun^ 

 together, and the tegmina and wings (even in the J) extending only a trifle beyond the tip of the hind 

 femora. 



Head a little wider than tbe front edge of the pronotum ; the occiput rather short and* not greatly rounded; 

 fastigium somewhat deeply sulcate and projecting in advance of the eyes a little further tban one-half 

 its diameter, its sides meeting in a right angle ( 6 ) or obtuse (?) in front, the anterior portion of the 

 sulcature provided with a well-marked median carina ; frontal costa fairly prominent, evenly divergent 

 and reaching the clypeus, scarcely sulcate, but provided with a few rather coarse punctures both abovei 

 and below the ocellus ; lateral foveolae rather deeply impressed, elongate^triangular. Antennas with the 

 joints depressed, shorter than the combined length of the head and pronotum in both sexes, Pronotum 

 with the sides gently compressed in the middle, the two lobes about equal in length ; lateral carinas 

 arcuate, approaching most closely at the second transverse sulcus, the hind edge broadly angulate. 

 Tegmina of moderate width, the costal edge near the base somewhat dilated ; discal area scarcely 

 narrowing distally, where it is occupied by two rows of cells, the ulnar area in the J irregularly veined. 

 Hind tibiae with 9 spines in the outer row. 



General colour variable, but often in great part green or testaceous, with the usual dusky bands reaching from 

 the back edge of the eyes to the hind margin of the pronotum, crossing over to tbe disc on the hind 

 lobe. Tegmina furnished with a longitudinal discal row of fuscous spots. In some of the darker-coloured 

 (brownish) individuals the entire tegmina are, more or less generally marked with fuscous spots, reminding 

 one of 0. punctata. 



Length of body, d 1 14-15, $ 20-21; of pronotum, tf 2-65, $ 3-95; of tegmina, <S 12, 5 16; of hind 

 femora,' <? 8-5, $ 12 millim.

23. Orphulella prominula, sp. n. 



Orphulella prominula, Scudder (MSS.). 



A medium-sized insect, with the antennae rather heavier than usual and somewhat longer than the combined 

 length of the head and pronotum, and the lateral carinae of the pronotum gently and evenly divergent 

 posteriorly. Face strongly oblique ; the eyes prominent and a little more elongate than usual. 



Head? rather long above, the fastigium about as long as wide, acute-angled, deeply sulcate and with a short 

 median carina in front, the lateral walls profound and rather sharp, the lateral foveolae faint, triangular. 

 Frontal costa rather prominent, evenly divergent, sulcate throughout. Pronotum with the last transverse 

 sulcus situated plainly behind the middle, the disc of the hind lobe above furnished on each side between 

 the median and lateral carinas with two longitudinal ridges or rugae. Tegmina rather narrow, irregularly 

 veined in the discal and ulnar areas, about reaching the tip of the hind femora. The latter about normal, 

 provided with twelve or thirteen spines in the outer row. 



General colour testaceous, with the upper third or fourth of the sides of the pronotum and the base of the 

 tegmina infuscated— possibly, in some specimens the prevailing tint above is green or flavous. Wings 

 hyaline, or very faintly clouded apically. 



Length of body, 6 , 16-17 ; of pronotum 3, of tegmina 13'5, of hind femora 9-75 millim. 



Hab. Mexico, Mazatlan (coll. Scudder), Presidio (Forrer). 

 Three specimens, all males.
