Trichodes peninsuiaris Horn. 



Trichodes peninsuiaris Horn, Proc. Cal. Acad. Sci., iv, ser. 2, 1894, 

 p. 382, pi. 8, fig. 7 



Similar in form and size to oresierus but less slender; head and 

 thorax violaceous, elytra dull blue black, with three yellow fasciae; 

 body beneath and abdomen shining olivaceous green. Antennae 

 entirely black. Head rather sparsely punctate, thinly clothed with 

 rather long hair; palpi pale. Thorax as long as wide, surface coarsely 

 punctate, dense at the sides, more sparse on disk; disk convex, a 

 slight depression at middle of base. Elytra parallel ; surface coarsely 

 cribrately punctate, feebly striate; apices truncate, sutural angle 

 distinct; hairs short, black and erect; fascia? narrow, yellow; a basal 

 fascia, broad at the humeri, extends slightly obliquely to near the 

 suture, thence turns abruptly parallel with the suture; a median and 

 a posterior fascia at apical fourth very slightly arcuate. Sides of 

 metastemum and the posterior margins of ventral segments two, 

 three, and four, clothed with long, dense, white hair. Abdomen 

 shining, smooth. Legs black, with bluish green luster. (Elytral 

 markings, pi. VI, fig. 22.) 



Closely allied to illustris Horn, but possessing distinctive char- 

 acters of apparently sufficient value to justify its retention as a valid 

 species. 



Occurs in Lower California at El Chinche. 



Trichodes illustris Horn.

fig- 

 This species resembles both oresierus and peninsuiaris in form and 



to some extent in markings. The more finely punctured head, red 

 antennal funicle, less evenly distributed abdominal hairs, size, color, 

 and markings will easily separate it from oresierus. From peninsuiaris 

 this species differs in having the head coarsely, densely punctate, the 

 legs (usually) and antennae red, the three apical joints of the latter 

 sometimes black, the ground color of the elj'tra dull ferruginous, the 

 fasciae and flanks bordered with black ; the fasciae are also of somewhat 

 different form, the first keeping close to the basal margin and pro- 

 longed posteriorly o^t the suture, the median fascia is more strongly 

 arcuate and the posterior fascia much more oblique. 



The writer has not seen the male of this species, all the specimens 

 at hand having the apices of eh-tra truncate and sinuate. In a 

 specimen from Fort Huachuca, Arizona, kindly loaned by Mr. F. S.
