126 GEO. H. HORN, M. D. 



I reproduce the description given by White. I ata unable to recog- 

 nize it either specifically or generically. It may be a Pogonocherus. 



ME€OTETARTUS Bates. 



in. antennattis Bates, Trans. Ent. Soc. London, 1872, p. 213 ; Eutessus 

 asper Lee, Classif. 1873, p. 339 ; New Species, pp. 235—236. 



Occurs from the Peninsula of California to Chontales, Nicaragua. 



DECTES Lee. 



D. spinosus (Say). 



I place Dectes here in preference to making it a distinct group as 

 the presternum is not narrower than in several Lepturges, and the 

 only characters remaining are the cylindrical form and erect hairs on 

 the elytra which seem too feeble to separate it in a group by itself. 

 It is therefore placed where Lacordaire left it, but I am unable in 

 our species to see the carina on the outer side of the antenna of 

 which he speaks. 



D. texanus Lee, is not sufficiently difi'erent from sj^inostis to be 

 retained as a distinct species. 



L,EPTURGE$!i Bates. 



The species here included are those in which the antennaB are 

 fimbriate beneath with very short hair, and the sides of the thorax 

 angulate near or in front of the base. The pro- and mesosteruum are 

 both very narrow, linear and barely wide enough to separate the 

 coxae. The fimbriae on the lower face of the antennae are, at most, 

 short and inconspicuous, and in some specimens I have seen are 

 almost entirely wanting. The tarsi are slender, the first joint of the 

 posterior pair being as long as the following joints united. 



As thus defined the genus contains not only those referred here by 

 Dr. Leconte, (Classif. p. 338), but also those considered Liopus, (see 

 also Check List, p. 91), L. higuttatus Lee, is however a Graphisurus. 



The species of the Amazons are divided by Mr. H. W. Bates in two 

 sections, which apply equally to those of our fauna, these are : 



Section A, lateral prominence of the thorax rather broad and very close to 

 the base. 



Section B, lateral prominence more slender and acute, the tip recurved, dis- 

 tant from the base. 



In A the posterior border of the lateral tooth slopes obliquely to 

 the basal margin of the thorax. 



In this section I find one species belonging, symmetricus Hald., 

 to which must be referred as synonyms pictus (PI. II, fig. 2), and 

 angulatus Lee, the former being a very perfectly marked specimen, 

 the latter contains those with the markings sufl'used.
