170 LONGICORNIA. 
The black spot near the base sometimes extends almost to the sides, like a fascia; and 
in the Chontales specimen the median spot is not dentate, but forms a nearly compact 
oblique fascia.

This is an elongate-oblong species, allied to L. multinotatus, clerulus, &c., having a 
similar trapezoidal form of thorax, with straight sides; the head in the middle is rosy 
red, like the surface of the thorax. In the description above cited I described as the 
female an insect which I now believe to be of a totally different species, in which the 
thorax is very similar in form to that of L. tumidicollis. 
17. Lepturges ruficollis. 
Lepturges unilineatus, Bates, Trans. Ent. Soc. 1872, p. 2877 (2 nec 3). 
Parvus, oblongus, parum convexus, niger, griseo-sericeus, thorace (supra et infra) femoribusque basi rufis, illo 
lateribus supra cano-pubescente; capite parvo (nigro), fronte infra angustata; thorace valde transverso, 
lateribus antice rotundatis, ante spinam hamatam angulatim dilatatis, sulco postico punctato; elytris apice 
obtuse rotundatis, dorso crebre punctatis, nigris, linea utrinque grisea interdum indistincta; femoribus 
posticis vix incrassatis ; antennis rufescenti-fuscis, articulo tertio quam scapus longiore.

L. twidicolls prima facie simillimus, at differt thorace angustiore trapezoidali lateribus rectis, elytrisque apice 
sinuatim oblique truncatis angulo exteriore producto. Elongato-subovatus, sordide fulvescens, capite antice, 
thorace vittis dorsalibus, elytrisque maculis variis fuscis, his partim fusco et fulvo marmoratis maculis 
utrinque tribus (prima centro-basali, secunda obliqua mediana tertiaque vitteeformi apicali) distinctioribus ; 
antennis pedibusque pallide testaceis, illis articulis apice, feomoribus (posticis exceptis), tibiis tarsisque apice 
atro-fuscis.

19. Lepturges stigmaticus. 
Parvus, oblongo-ovatus, rufo-testaceus, elytris utrinque litura curvata atro-fusca sub humero incipiente versus 
discum curvata et ante marginem postico-lateralem desinente ; thorace et elytris atomis fuscis quoque 
sparsis, apud thoracis discum et versus elytrorum apicem in maculas aggregatis ; antennis pallidis, scapo 
annulo mediano, ceteris articulis apice atro-fuscis ; pedibus rufo-testaceis, tibiis apice tarsisque nigro 
maculatis ; thorace transversim quadrato, vix antice angustato, spina laterali paulo ante angulum sita,
