123. Chlorus bolivianus sp. now 



Very similar in size and general form to both C. vittatus and C. 

 brunneus, but differing from them in color. Inner face of hind 

 femora totally black, the lower sulcus deep blue-gray. Body rather 

 profusely hirsute. 



Head large, about as wide as the front edge of the pronotum. Eyes 

 large and moderately prominent, in the male nearly as broad as long, 

 the latter dimension almost a third greater than the length of the 

 anterior edge of the cheeks; in the females decidedly longer than 

 broad, the former dimension little if any greater than the length of 

 the anterior edge of the cheeks below them; vertex between the eyes 

 about twice (d 71 ) or three times ( 9 ) as wide as the diameter of the 

 antenna;, the fastigium rather large and depressed, strongly sulcate, 

 spatulately widened toward the front. Frontal costa rather promi- 

 nent, a little narrowed above, roundly sulcate throughout, but more 

 profoundly so at ocellus, sparsely punctulate above the ocellus. 

 Antennae filiform, a little heavy, slightly surpassing the hind margin 

 of the pronotum in both sexes. Pronotum rather robust, very 

 perceptibly divergent to the rear, viewed sidewise gently arcuate 

 above, without definite lateral carinae, the lateral lobes somewhat 

 tumid viewed from above, transverse sulci fairly deeply impressed, 

 all three cutting the median carina, the last plainly back of the 

 middle; anterior edge above truncate, posterior margin broadly 

 rounded. Tegmina rather large, almost as broad as long, the apex 

 as well as the costal and dorsal edges evenly rounded, the inner 

 margins almost touching, closely and finely veined, extending well 

 over the basal abdominal segment. Abdomen normal, in the male 

 gently clavate; male cerci evenly tapering on basal half, beyond which 

 point they are nearly equal and abruptly bent inward and backward, 

 the apical half somewhat flattened and obliquely docked from above. 

 Legs a little coarse or robust, in the female about reaching, in the male 

 a little surpassing, the apex of the abdomen; hind tibia? 8-spined on 

 the outer edge. Prosternal spine of medium size, slightly transverse, 

 acuminate, and gently directed to the rear; interspace between the 

 mesosternal lobes about as broad as long, but plainly narrower than 

 the lobes themselves. 



General color above rather dark wood-brown varied with patches 

 of lighter hues and flecks and dashes of fuscous; front, anterior and 

 middle legs, and underside testaceous; lower half of the lateral lobes
