50 FAMILY I. — SCUTELLERID>E. 



with sides shallowly finely and rather closely punctate; the middle of 

 abdomen more sparsely so. Length, 4 — 4.5 mm. ; width, 3 mm. 



Dunedin and Caxambas, Fla., Feb. 8 — March 8. Recorded also 

 by Barber from Estero, Biscayne Bay and Key Largo, May- 

 November. Germar's type was from California and in this 

 country it is recorded only from that State, Vancouver, B. C, 

 Texas and Florida. My specimens were taken by sweeping 

 low shrubs, as huckleberry, etc., in open pine woods. The C. 

 pullatus Dist. from Guatemala and Colombia is a synonym. 



IX. ACANTHOLOMA Stal, 1867, 491. 



Small oval species, very closely related to Camirus, but less 

 convex, with head and pronotum broader, their side margins 

 finely and irregularly toothed ; second antennal twice the length 

 of third. But one species is known. 



13 (8). ACANTHOLOMA DENTICULATA Stal, 1870, 17. 



Oblong-oval, moderately convex. Dull black, minutely pubescent 

 with yellowish prostrate hairs ; antennae and tarsi dull brownish-yel- 

 low; scutellum with a small round smooth pale spot each side at base. 

 Head strongly declivent, rounded in front, coarsely, densely, cribrately 

 punctate, its side margins carinate, the carinae dentate, broadly in- 

 terrupted near base, forming a short toothed lobe in front of eyes; tylus 

 scarcely longer than cheeks, separated from them each side by a deeply 

 impressed line. Pronotum at apex one-third wider than head, its disk 

 more finely punctate, the submedian transverse groove deepest at middle; 

 lateral angles broadly rounded, front side margins almost straight, finely 

 dentate. Scutellum covering both elytra and connexivum, its disk at 

 middle a little more sparsely and deeply punctate than pronotum, with a 

 vague transverse curved line across basal third and traces of a median 

 lengthwise carina. Under surface closely and finely punctate, the center 

 of abdomen more sparsely so, the fourth and fifth ventrals with a smooth 

 oblong space each side of middle. Genital plate of male broadly semi- 

 circular with a fine median lengthwise carina on front portion, behind 

 which is a transverse impressed line followed by a fine transverse ca- 

 rina; punctures on front portion each side of median carina deep and 

 closely placed ; hind or apical margin of the plate truncate. Length, 5.3 — 

 5.7 mm.; width, 3 — 3.5 mm. 



Lake Co., Ind., June 4 {Gerhard) ; taken from beach drift. 

 Northern Illinois (Hart). Described from Illinois and recorded 

 also by Van Duzee from Indiana and Kansas.-" Resembles 



20 A male in the U. S. Xational Museum from Riley Co., Kansas, collected by Mar- 

 latt in June and determined by McAtee as A. denticulata, differs from typical Illinois 

 specimens of that sex as follows: Smaller, length 5 mm.: antenna- and tarsi darker, 

 pale spots at base of scutellum one-half the size: genital plate without carinae or 

 transverse impression, its surface even, with finer, much more shallow punctures and 

 hind or apical margin distinctly convex It may be known as var. kansiana.
