26 THE CANADIAN ENTOMOLOGIST. 



in profile the apex obtusely rounded angulate, the frontal costa depresso- 

 convexed in front of the eyes and advanced in front of the eyes about 

 one-fourth their width ; below the face is moderately declined ; as seen 

 in front the frontal costa is strongly sulcate, the branches commencuig 

 near the apex in front are gradually divergent to the middle ocellus, where 

 they are more than usually separated. Eyes very prominent and globose. 

 Antennie very slender, reddish, inserted a little above and in front of the 

 anterior inferior border of the eyes. Pronotum anteriorly angulate, the 

 sides substraight, posteriorly long and subulate ; the apex acute, passing 

 the posterior femora ; dorsum smoothly granulate, with no longitudinal 

 wrinkles, or scarcely a vestige of vein-like arrangement of the granules 

 between the shoulders ; median carina distinctly elevated, nearly straight 

 or gradually arched a little higher between and a little in front of the 

 shoulders ; humeral angles very obtuse, surface of dorsum between them 

 tectiform ; the anterior carinae are curved, becoming a little divergent 

 posteriorly ; the borders of the posterior angle of the lateral lobe nearly 

 form a right angle, acute at the apex ; the posterior margin is straight and 

 vertical. The elytra are nearly smooth externally, with a short thick 

 oblique pale line very near the apex. Femora normal, the anterior and 

 middle femora somewhat slender ; the posterior femora rather broad, the 

 first article of the posterior tarsus equals the third in length ; the pulvilli 

 subrounded below, the third is little the longest. 



Length : body, c? • i 2 mm., pronotum 13 mm., post. fern. 7 mm. The 

 wings extend beyond the apical process of the pronotum one millimetre.

 Tettigidea chichivieca ausiralis, form. nov. 



Body rather small, fuscous, above ferruginous obscurely clouded with 

 fuscous ; face below the eyes light, spreading laterally over the lower 

 portion of lateral lobes, pale underneath the abdomen ; femora light* 

 obscurely clouded ; tibia a little more distinctly striped with fuscous. 

 Vertex scarcely narrower than an eye, obtusely angulate in front, a little 

 produced in front of the eyes, the front margin formed of little lateral 

 carinas directed obliquely backwards and ending near the anterior inner 

 angle of the eye, where the eye is a little conically elevated, feebly sulcate 

 on each side longitudinally, the little lobes not very distinct, middle 

 carinaled, posteriorly extending only as far as the lateral carinae, anteriorly 

 coalescing with the shining frontal costa ; in profile the vertex is obtusely
