 Acalypta mniophila Drake and Ruhoff 1959, p. 136, fig. 1. 



Brachypterous form. — Obovate, widest behind middle of elytra, 

 fuscous-brown with pronotum and costal areas brown; body beneath 

 blackish fuscous. Pronotum reticulate with areolae about same size 

 as those in paranota, unicarinate; median carina low, composed of 

 one row of very small areolae; hood low, obtusely projecting forward 

 between eyes; paranota rather narrow, biseriate, with anterolateral 

 corner rounded. Hypocostal lamina uniseriate. Elytra very convex; 

 costal area narrow, mostly uniseriate, with a few extra areolae in apical 

 third. Antennal measurements: segment I, 0.11 mm.; II, 0.08 mm.; 

 Ill, 0.40 mm.; IV, 0.22 mm. Length 2.00 mm., width (elytra) 1.25 

 mm. Macropterous form and male unknown. 



HoLOTYPE. — Brachypterous 9, Central Mexico, on moss, Aug. 16, 

 1947, in U.S. National Museum (type no. 64870), illustrated. 



Distribution. — Known solely from the type specimen from 

 Mexico. It can be distinguished from the species of Acalypta of the 

 New World possessing unicarinate pronotum (saundersi and duryi) 

 by the much narrower paranotum and costal area as depicted in the 

 figures. The pair of frontal spines on the head is obsolete. The 

 same structures distinguish it from A. sauteri from Japan.

Brachypterous form. — Oblong, fuscous-brown to dark fuscous, 

 body beneath stramineous to blackish fuscous; rostral laminae of 

 sternal sulcus brownish. Legs slender, dark brown with femora 

 tending to be fuscous. Antenna brownish fuscous. Length 2.20- 

 2.55 mm., width (elytra) 1.12-1.30 mm. 



Head short, armed with two porrect, frontal spines. Antennal 

 tubercles spiniform, divergent. Antenna long, slender, fourth seg- 

 ment fusiform, segmental measurements: I, 0.18 mm.; II, 0.08 mm.; 

 Ill, 1.11 mm.; IV, 0.20 mm. Pronotum coarsely punctate, depressed, 

 tricarinate, each carina strongly foliaceous, composed of one row of 

 quadrate areolae, the lateral pair almost as highly elevated as median, 

 slightly divergent posteriorly; paranotum wide, triseriate in form, 

 biseriate opposite humeral angle, outer margin nearly straight; 

 anterolateral corner distinctly angulate, often with a tooth or spine- 

 like lateral projection. Legs slender, femora only a little swollen.
