This species was described from Titusville, Florida, but I am 

 unable to find anything in the description by which it differs from 

 pygmcea, unless it is the ^^ relativ kurze, hochgeivdlhte Halsschild.'" 

 The thorax \n pygvicea cannot be called very convex, though, if com- 

 pared with arboricola, it is certainly more convex than in that species. 

 It is said to be related to marginata and columbica, and with the first 

 of these two, pygvicea was given by Gemminger and Harold as a 

 synonym. From his remark " die kleinste der mir bekannteti Strigoder- 

 men,'' it seems that Dr. Ohaus did not '^xd.wt pygviaa when he described 

 hisfloridana, as the size he gives for the latter species is exactly that 

 oi pygmcea, of which I have even smaller specimens than 5.5 mm. 

 in length. 



Strigoderma viridicollis, new species. 



Form of arboricola, head, thorax and sculellum bright green, thorax with pale 

 side margin, legs pale with greenish luster. Head coarsely and densely punctate, 

 clypeal margin obliterated ; clypeus moderately reflexed. Thorax not quite twice as 

 wide at base as long ; sides feebly arcuate ; apical angles subacute, basal angles 

 rounded ; surface coarsely punctate, densely at sides, slightly more sparsely on the 

 disk, intermixed with a few finer punctures, pubescence moderately long, erect ; at 

 sides two oblique impressions, one starting from near the apical angles and the other 

 below this, median line impressed but not reaching base or apex. Scutellum irregu- 

 larly punctate, punctures finer than those on thorax. Elytra one and a half times as 

 long as wide at base, feebly arcuately narrowing to apex ; surface striate-sulcate, 

 punctures of striae large and shallow ; intervals very convex, as wide as the striae. 

 Pygidium transversely rugose, sparsely hairy. Front tibise bidentate ; front and 

 middle outer claw cleft, the upper part much narrower and slightly shorter than 

 the lower. Metasternum coarsely punctate ; abdominal segments more finely and 

 sparsely. Length 9 mm.

I received this as a new species, a few years ago, from Mr. E. A. 

 Schwarz. 



This species, of which I have seen only males, looks very distinct 

 from arboricola, but I am unable to point out a good character to 

 separate the two, except the color, which, according to a note made 

 at that time, is constant. It is possible that Casey's pima/is, which I 

 do not know, connects the two. The color is pale testaceous, the 

 underside, the front and middle femora entirely, and the lower half of 

 hind femora bluish black ; the pygidium, tarsi and upper half of hind 

 femora testaceous with greenish luster ; the suture greenish, a few of 

 the costae at sides and antennae piceous ; the head, thorax and scutel-
