ad apicem ramiim gracilem emittentihus, 4 — 1 1 extus tricarinatis. Th or ax 

 quadratus, medio utrinque spina longa, robusta, armatus ; mar gine post ico 

 medio quadratim lohntiis. 



Agi'cos with Anacolus in its well-developed second antenna,] joint ; 

 but in sculpture the joints 4 — 11 have the earinated form of Mijzo- 

 morplms, instead of the numerous stria) of AnacoJiis. The antennae are 

 longer and more slender than in either genus, and the branches 

 emitted \>y joints 6 — 10 are much narrower and more pointed. The 

 thorax is sinnlar in form to that of Myzomorplms ? , but the lateral 

 spine is more median, longer and stronger, and placed much above the 

 lateral rim, and the hind margin is produced into a broad truncated lobe 

 over the base of the scutellum. The prosternal process is broad and 

 flattened ; the mesosternum deeply sulcate in the middle. The meta- 

 thoracic epistcrna are not cut obliquely on their outer side, but are 

 nearly parallelogrammical in outline. 



TEMlfESTHES LOBICOLLIS, U. sp.

 elytris violaeeis basi late aurantiacis ; pedibus, pectoris medio abdomine- 

 que Jlavo-testaceis ; capite tlioraceque creberrime punctulatis, breviter 

 pubescent ibus, hoc incequali, medio et postice depresso ; scutello grosse

Broad and plane on the upper-surface, scarcely shining, the 

 thorax, undcr-surface and legs clothed with a short erect blonde pu- 

 bescence. The apical joints of the palpi are triangular. The thoracic 

 spines are long, robust, and laterally compressed, and are quite detached 

 from the lateral rim of the pronotum ; the surface of the thorax is 

 unequal, and broadly depressed in the middle. The elytra reach to 

 the apex of the third ventral segment ; their sutural edge is strongly 

 incurved a short distance behind the scutellum, and each elytron thence 

 tapers to the obtusely pointed apex ; their surface is very closely but 

 not finely punctured ; the lateral margin is fulvous for a short distance 

 behind the shoulders.

 collection.
