NORTH AMERICAN BOSTRICHIDAE 77 



that of the prothorax, the interspersed pointed tufts of blackish hairs longer and 

 very conspicuous. 



Length, 7 inni. ; width, 2.4 mm. Santa Rosa, Lower California (Beyer). A most 

 singular insect, totally different in its vestiture from any species previously known 

 to us. 



The elytral fasciculae are approximately as follows : A subsutural series of 

 three prominent tufts, exterior to which are three or four others less regularly 

 placed; a sutural series of much smaller tufts, and a number of similar ones 

 toward the side margin.

Specimens of this species have not been seen by the writer and the 

 species has been placed in the key from the characters given in the 

 original description. It seems advisable therefore to include the fol- 

 lowing copy of the original description :

Lichenophanes arizonicus, new species 



Elongate, cylindrical, uniformly reddish brown ; the palpi, antennae, 

 and tarsi sometimes slightly paler; dorsal surface of body sparsely, 

 irregularly clothed with short, recumbent or semierect, yellowish 

 hairs. 



Head much narrower than pronotum, finely, densely tuberculose, the 

 tubercles distinctly separated on vertex; clypeus slightly convex; 

 clypeal suture distinct; labrum densely ciliate with long, yellow hairs 

 in front. Antenna 9-segmented; third segment elongate, twice as 

 long as fourth, fourth round, fifth and sixth transverse. 



Pronotum quadrate, strongly convex, widest near middle, strongly 

 deflexed on apical half, with two unciform processes in front, with- 

 out depressions or distinct gibbosities in front of scutellum; sides 

 broadly rounded, more strongly converging anteriorly; posterior 

 angles slightly rectangular; surface with a narrow, longitudinal, 

 median, smooth space, densely, coarsely tuberculose, the tubercles 

 small, round, and polished on basal half, larger, broader, and rasplike 

 on apical half. 



Elytra at base subequal in width to pronotum at middle, truncate at 

 base, without longitudinal costae; sides parallel, conjointly broadly 

 rounded at apices; surface coarsely, deeply, densely punctate, coarsely 

 rugose between punctures. 



Abdomen beneath very finely, densely granulosa, sparsety clothed
