The species in this genus are distinguished from Panops by 

 their geographical range, metalHc colors and the position of the 

 antennae. They differ from Eidonchus in the structure of the 

 proboscis, the absence of the palpi and there is a slight difference 

 in the venation. The eyes are widely separated below the 

 antennae. 



Lasia klettii 



Lasia klettii O. S., Report on Wheeler's Survej-, v, Zoology, p. 804, (187.3). 



"Metallic green; feet black. Length, 17 mm. (through body end to end). 

 Altogether metallic green, with golden reflections, the upper side finely and 

 evenly punctured; venter more bluish; feet altogether brownish black, by one 

 half longer than the body; antennae very short, black; base of third joint 

 slightlj' reddish; this joint more than twice as long as the first two together, 

 gradually tapering toward the tip. Wings distinctly infuscated; tegulae 

 brownish, bordered black. Alcohol took off all pubescence; some vestige on 

 thorax proves that it was clothed with short pale hairs. 



"Camp Apache, Ariz., September, 1873. Collected by Francis Klett. 



"Observation — I place this species provisionally^ in the genus Lasia, to which 

 it is related. It differs from Wiedemann's figure of Lasia in the fact that the 

 second longitudinal vein ends in the first and not in the costa. It differs from 

 Eulonchus in the eyes being contiguous between the antennae and the vertex 

 only, and not above and below the antennae. The abdomen is very convex; it 

 is broad and cut squarely at the base; broad and blunt at the tip (not tapering 

 as in Eulonchus). In the figure the hind tarsi are broken off." 



Dr. Williston published on this species in these Transactions. 

 He had two specimens of a large and beautiful Cyrtid from New 

 Mexico. "The species is almost entirely bare, the sparse, short, 

 black and light colored hairs on the dorsum of the thorax are 

 hardly discernible. In the South American species of the genus 

 Lasia there is always considerable vestiture. This fact and the 

 termination of the second vein in the first makes its location in the 

 genus doubtful. In these specimens I can see scarcely any golden 

 reflections, but, on the contrary, a pronounced blue or violet re- 

 flection, almost obscuring the green of the abdomen of one. The 

 stumps of veins on the anterior branch of the third vein and near 

 the tip of the fourth vein are wanting." 



If the two specimens above mentioned are the ones now in the 

 Kansas University collection, and it is very probable that such 

 is the case, they should be placed under Lasia scribae 0. S.
