 parallel and approximate carinse running from the front border of the pro- 

 notum to the vertex, the median continuous to the tip, the lateral bend 

 suddenly outward opposite the upper canthus of the eyes, and from thence 

 forward are continuous with the raised margins of the vertex. The vertex 

 not expanding in front of the eyes ; no lateral foveolse. Face oblique, nearly 

 straight; frontal costa rather broad, narrowest above, regularly and gradually 

 expanding below, flat; margins square. Eyes oblique, acuminate above. 

 Antennae not reaching tlie tip of the pronotum, large, flattened, enlarged 

 almost into a club at the apex; joints quite short and sub-distinct. Prono- 

 tum very slightly contracted in the middle, expanding slightly hindward; 

 the three carinoe about equal, the lateral somewhat approximate, a little in 

 advance of the middle ; very shghtly divergent from this point forward, a 

 little more divergent posteriorly ; hind border obtusely rounded. Elytra and 

 wings about as long as the abdomen ; posterior femora about same length.

 of the head and pronotum sometimes dark-brown, sometimes ash-brown. 

 Upper half of the sides of the pronotum usually liglit-brown, yellowish 

 below. Elytra pale-brown, translucent at the apex; a row of oblong, dark 

 spots along the middle field, some four or five, often running together and 

 forming a stripe. Wings transparent at base (probably slightly colored when
