[August — December 1SS9. 



upon which it is based I do not find 



anywliere described, and so give it 



here. 



Cyphototnyia lynchii^ sp. nov. 



Antennae black, long (about as long 

 as the hind femora) ; first joint about as 

 long as the third, with hairs above, 

 and a few bristles below ; second joint 

 short, with bristles ; third joint slender, 

 pointed, without style, black pubescent. 

 Face and front densely yellowish gray 

 pubescent ; face a little wider above, 

 very slightly projecting below, with a 

 few fine black bristles on the lower part. 

 Front very deeply excavated, and very 

 broad above, the inner margins of the 

 eyes convex, the ocelligerous tubercle 

 small and (in the single specimen) 

 without bristles. Head nearly twice 

 as wide as high, flat, the eyes disci- 

 form, and with distinctly enlarged facets 

 in front. Proboscis not long, truncate, 

 black. Thorax black, pvmctulate ; me- 

 sonotum remarkably projecting above in 

 front, forming a hemispherical protuber- 

 ance, laterally constricted at its base. 

 Abdomen black, slender, acuminate, 

 strongly punctulate, the segments with- 

 out lateral bristles. Femora black, tib- 

 iae and tarsi yellow, except that the tips 

 of the four anterior tibiae, the distal part 

 of the hind pair, and the last two or 

 three joints of all the taisi, are brown 

 or blackish ; tibiae and tarsi with slender 

 yellow bristles ; hind tibiae on the inner 

 side with yellow pile as in most species of 

 Cerotainia and Atomosla. Wings 

 lightl}^ infuscate (from the microscopic 

 pubescence) ; petiole of marginal cell 

 long; first and second posterior cells of 



nearly equal width distally, long ; veins 

 at outer end of the discal and fourth pos- 

 terior cells nearly in the same straight 

 line ; small cross- vein before the middle 

 of discal cell. Length 5 mm. 



One specimen, Chapada (near Cuy- 

 abA) Brazil, H. H. Smith. 



Schiner long ago (Verb, zool.-bot. 

 Gesellsch, 16,664) called attention to 

 the artificial position oi Atractia among 

 the asi'linae, sensu auctorum. I can 

 only reiterate it, and protest against 

 any classification that separates the 

 genus from the immediate neighbor- 

 hood of Atomosia^ sensu strictiori. 

 Indeed, as Schiner says, when the third 

 antennal joint in any specimen is want- 

 ing, the species will be unhesitatingly 

 referred to that genus. To separate 

 Atractia^ then, into another subfamily 

 on the slight difierence between a slen- 

 der style (as in Atonia mikii Will.) 

 and a short bristle, is absurd. Atractia., 

 at present, includes but four species, 

 three from South America, and one 

 from Central America. Two addi- 

 tional species are represented in the 

 Smith collection. Another species, of 

 much larger size, and different appear- 

 ance, also new, but more nearly related 

 to some of the described species, has 

 the abdomen entirely smooth, without 

 punctulation, the proboscis longer, 

 etc. ; it may require the erection of 

 a new genus for its reception. As in 

 many of the species of the Atowosia 

 group of genera, all these species have 

 a minute projection on the upper border 

 of the third antennal joint.
