LOPHYEOIDES.

The palpi in this genus are short, thick, and sparsely covered with longish bristle- 

 like hairs, the last being also the case with the maxilla ; the labial palpi are 3-jointed, 

 the first joint is longer than the second and a very little shorter than the third, which 

 is brought to a blunt point in the middle at the apex. The maxillary palpi are 

 4-jointed ; the first is thicker than the second, and projects on the lower side ; the third 

 is a little longer than either the first or second ; the fourth is a little longer than the 

 two preceding together, besides being thicker than them. The mandibles are stout, 

 rather blunt at the apex, and have no subapical tooth. The second cubital cellule usually 

 receives both recurrent nervures ; but the second may be interstitial or nearly so. The 

 position of the second transverse cubital nervure is subject to irregularity; and this 

 will lead to a corresponding change in the relative position of the second recurrent 

 nervure ; the second tansverse cubital nervure is often absent. The appendicular cellule 

 in both wings is small. The calcaria are simple, broad, and do not much exceed one 

 third of the length of the metatarsus, which is a little shorter than the three following 

 joints ; the last is longer than the two preceding ; the patellae are obsolete ; the claws 

 long, curved, simple.

 Lophyrus tropicus, Norton, Trans. Amer. Ent. Soc. ii. p. 322; Catal. p. 176 ((J) 1 . 



Hab. Mexico (de Saussure 1 ); Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



I believe the specimens from Chiriqui are correctly identified with Norton's species. 

 The third cubital cellule is scarcely half the length of the second, and the third trans- 

 verse cubital nervure is often absent. The sutures on the vertex are very deep, as is also 

 the transverse furrow behind the ocelli and the longitudinal one in the centre of vertex. 

 A wide furrow runs from the ocelli to the antennae, becoming wider towards the apex. 

 In the male, however, the sutures on the vertex are less clearly marked, and the 

 central longitudinal one on the vertex is absent. The wings vary in the intensity of the 

 colour, and as a whole the males have them lighter in tint.

This species seems scarcely to differ from L. tropicus.
