of head by a little over half its length, second about one-third 

 longer than first, third somewhat shorter than first, rostrum 

 reaching middle of third ventral segment, first joint somevi^hat 

 longer than head. Pronotum rather strongly narrowed from 

 base to apex, with a shallow, rather indistinct, transverse im- 

 pression somewhat before the middle, lateral margins narrowly 

 reflexed, a little sinuate at the transverse impression, basal 

 margin straight in front of scutellum, anterior lobe finely and 

 thickly punctate, its disk with an oblique, smooth impression 

 on each side, and a small rounded impression in the middle, 

 the coarsely and sparsely punctured collar very distinct, ter- 

 minated behind by a deeply impressed rather strongly curved 

 line, posterior lobe coarsely and somewhat sparsely punctate, 

 with a short longitudinal median ridge in its anterior part. 

 Scutellum plane, coarsely and sparsely punctate. Elytra with 

 their costal margins parallel through the basal third of corium, 

 then a little ampliately rounded, clavus in addition to the usual 

 rows of coarse punctures with a few stray impressed points 

 between the posterior halves of the second and third rows, 

 corium coarsely and moderately thickly punctate, more sparingly 

 so in the white spots, the median vein arising behind middle of 

 mesocorium with two basal branches, a shorter one from the 

 radial and a longer one from the cubital vein, after the junction 

 of the branches, slightly curved outward, the two outer veins 

 (third and fourth) of the membrane united by two cross veins. 

 Pectus coarsely and somewhat sparsely punctate, metapleura 

 much more thickly punctate, but their posterior borders very 

 sparingly so, evaporative area extended outward somewhat 

 beyond apex of orificium, but conspicuously narrower than the 

 remainder of the metapleura, its outer margin a little rounded. 

 Abdomen beneath densely and finely strigulose and, moreover, 

 thinly, finely, and superficially punctulate. Front femora armed 

 with a few spines near apex ; the spines of all tibiae shorter than 

 the tibial diameter ; first joint of- hind tarsi more than twice 

 longer than the other joints together. 



Length, female, 9.5 millimeters; width, 3.8.

This remarkable species diff"ers from the others known to 

 me by the rather long acute head, less declivous antenniferous 

 tubercles, and therefore greater distance between eyes and base 

 of antennae, pronotum from base to apex more strongly narrowed 

 with sinuate lateral margins, and posteriorly more ampliate 

 costal margin of corium; in its general aspect it is also very 

 unlike the typical forms of Lcthaeus. Yet some of the known
