118 AMERICAN COLEOPTERA. 



length, as long as the third and fourth together, the fifth about five 

 times as long as wide, sixth arcuately dilated internally ; seventh 

 longer, eighth shorter and narrower than adjacent joints. Prothorax 

 two-thirds wider than long, minutely punctulate, hind angles acute 

 and moderately produced. Scutellum minute, equilateral. Elytra 

 rather numerously and distinctly punctate; sutural stria fine, not flexed 

 outwardly at base. Beneath impunctate ; mesepimera extending two- 

 thirds to coxae, metepisternal suture distinctly oblique ; post coxal 

 plates well developed, subparabolic in outline, that of the firsf ventral 

 two-fifths as long as the segment, more oblique externally. Hind 

 tarsi nearly or quite as long as the tibiae, basal joint quite as long as 

 the next two. Length, 1.5 mm. ; width, .9 mm. 



Mobile, Alabama. Eight examples very kindly given me 

 by Mr. Loding. 



According to Mr. Loding's labels specimens were taken 

 in fungus on oak and under bark. This is quite the prettiest 

 species of the genus, and the only one thus far known in our 

 fauna with elytral maculation. The post-coxal plates are 

 better developed than usual, but not more so than in evanes- 

 cens, which it should follow in Casey's table. 



S. terminata Melsh. 



Opportunity is here taken to call attention to an erroneous 

 statement in Casey's Revision of the Scaphidiidae with regard 

 to the antennal structure in this species. The sixth antennal 

 joint is there said to be "distinctly longer than the third, 

 fourth and fifth combined," whereas an examination of 

 typical examples in the LeConte and Melsheimer collections 

 show that the fifth and sixth joints are subequal, the latter 

 much shorter than 3-5 united. The metasternum is also 

 finely and sparsely punctate, and the length is 1.5 mm. 

 instead of metasternum coarsely punctured and length 1.8 

 mm. as stated by Casey, who evidently had something quite 

 different in hand. The true terminata will retain its position 

 in the table next to evanescens, but just what differential char- 

 acters should be given to separate these two I am now un- 

 able to say. In its strongly developed post-coxal plates and 

 posteriorly very broad metepesterna with strongly oblique 

 suture evanescens possesses two very unusual characters, and 

 it is highly probable that it differs in one if not in both 

 respects from terminata.
