T. D. A. COCKERELL. 145 



cell not appendiculate, second subniarjiinal narrowed above. Legs very dark 

 brown, tarsi dark ferruginous, pubescence of legs sparse and pale. Abdomen 

 shining black, tbe sides with a slight green lustre, pubescence sparse and brown- 

 ish. Just enough on binder jiart to make it look slightly dusty; punctures sparse 

 and extremely minute. 



Hab. — San Rafael, Vera Cruz, March 9, on yellow flowers of 

 Melopodiam (C. H. T. Townsend). Easily recognized by its small 

 size and coloration. It might be taken for an Halictm at a glance, 

 but the eyes are emarginate ; and the gi-eeu is a sort of Prussian 

 green, quite different from that comnjonly observed in Halidas. 



(3.) Augoclilora subignita n. sp. 9- — Belongs to section with large 

 spines on spur. Length about 8 mm. Head and thorax bright green, very densely 

 punctured. Abdomen metallic crimson, inclining to violaceous or purple, rather 

 sparsely punctured. As compared with A. pura (which is not closely allied, but 

 is chosen because it is a common species, in everyone's possession), the face is de- 

 cidedly broadly in the middle, but the distance between the lateral ocelli and the 

 eyes is not quite so great ; the face below the antennse is shorter, and the antennae 

 are somewhat wider apart, with a more elevated ridge between them ; the black 

 area on the clypeus is larger; the antennae are about the same, except that the 

 scape is more slender ; the punctures of the mesothorax are larger and more dis- 

 tinct from one another ; the middle of the mesothorax is rather inclined to brassy ; 

 the tegulse are larger and partly green behind ; the sparse hairs on the dorsum 

 of the thorax are partly black ; the enclosure of the metatborax instead of being 

 covered with longitudinal grooves or wj-inkles is smooth at the base, with two 

 oblique bands of very short wrinkles, meeting in the specimen described at an 

 angle of about 125°, but variable. The wings are uniformly smoky, the costal 

 nervure black, the other nervures and stigma dark sepia brown ; marginal cell 

 appendiculate. Legs mucli as in pura, but the hind legs decidedly stouter 

 throughout, the hindmost spur of hind legs with six long spines. Abdomen 

 crimson with purple tints, hind margins of segments with thin, very narrow 

 bauds of fulvous hairs ; venter dark, with yellowish white hairs. 



Hab. — San Rafael, Vera Cruz, March 13 and 14, on flowers of 

 plant No. 7 (C. H. T. Townsend j. Resembles A. ignita Sm., but 

 the abdomen is not so brilliant, more violaceous, wings not clear and 

 the nervures not testaceous. A. ignita belongs to a different section 

 of the genus by the character of the spur. In many respects A. 

 subignifa more resembles A. acidalia Sm,, from Uruguay, but the 

 abdomen is not "very ffnely" punctured. A. vesta ^m. seems also 

 allied, but is evidently distinct. 



(4.) Allgochlora ignita Smith.— Belongs to section with .spur ciliate. The 

 %. hitherto undescribed, differs by having the end of the clypeus whitish and 

 the first joint of the flagellum rufous. 



Hab. — San Rafael, Vera Cruz, last of June, many on flowers of 

 Cordia, probably C. ferniginea, according to Dr. J. N. Rose (C. H. 



TRANS. AM. ENT. SOC. XXIV. (19) JUNE, 1897.
