44 FAMILY I. — SCUTELLERID^E. 



these numerous along the sides, but sparse and much scattered on middle 

 of abdomen; antennae and legs yellow, the latter with numerous large 

 black dots. Head nearly an equilateral triangle, its apex obtuse. Prono- 

 tum as described above, its posterior side margins sinuate, disk with a 

 small nodule near each hind angle, and a large shallow impression be- 

 hind each front one. Scutellum with posterior declivity feebly but 

 distinctly carinate and sides rather strongly sloping downward. Male 

 with hind margin of sixth ventral broadly and deeply concave; genital 

 plate twice as wide as long, its hind margin emarginate. Female with 

 medium segment of genital plate very small and rounded. Length 8 — 11 

 mm.; width 5 — 7 mm. 



Dunedin, Lakeland, Istokpoga, Miami, Royal Palm Park and 

 Cape Sable, Fla., Nov. 21— April 12 (W.S.B.). Ft. Valley, 

 Ga., April (£/. S. N. Mus.). xa Recorded also by Barber from 

 Enterprise, Fla. It is a tropical form originally described from 

 Rio Janeiro and Bahia, Brazil, and recorded by Uhler (1886, 2) 

 from Mexico. About Dunedin it is, next to Homoemns parvulus 

 (Germ.), the most common member of the family, occurring 

 in fall and spring mostly on the foliage of the wax-myrtle, 

 Cerothamnus ceriferus (L.) and hibernating in bunches of Span- 

 ish moss, the axils of thistles and other convenient hiding 

 places. Like some of its allies it is very inconstant in its mark- 

 ings. The punctures of pronotum and scutellum, usually black- 

 ish, are sometimes in part as green as those of Diolcus chrysor- 

 rhceus. The fuscous spots vary exceedingly in form and size. 

 Of 16 specimens before me, six, equally divided as to sex, have 

 the declivity of scutellum almost covered by a large sharply 

 defined piceous spot, this being deeply emarginate on its hind 

 border. In the other specimens no trace of this spot is visible 

 and some of them are almost devoid of fuscous markings ; while 

 one from R. P. Park has both pronotum and scutellum in great 

 part black. This is doubtless the species mentioned by Malloch 

 {Hart, 1919, 171) as being in the Bolter collection from Indian 

 River and Point Orange, Fla. As already stated it is not in- 

 cluded in the Van Duzee Catalogue, being confused by that 

 author with Stethaulax marmoratus (Say) , he having so identified 

 specimens of the Symphylus for me. 



VI. Stethaulax Bergroth, 1891, 235. 



Small broadly oval, somewhat flattened species having the 

 head short, broad, almost flat above; tylus feebly convex, 



18 Sent me as Stethaulax marmoratus (Say).
