1388 PAMIIvY l.XII. ANTHICID.E. 



north of Marion and Putnam (*onnties, though p]'ohal)ly occurs in 

 fewer numbers. January 21-I)eceml)er 8. ]\Iost eonunon in spring 

 and fall beneath eliips, iiiuncin leav<^s, stones, etc., and hibernates 

 in similar i)laees. T. inicrruptus Laf. is a mere form in which the 

 basal portion of elytra is more extended, with the rows of punctures 

 less regular. Intergrades between the two are eonunon in the col- 

 lection at hand. 



IX. Malporus Casey. 1895. (Gr., "bad + walker.") 



Rather slender, ant-like species, possessing the characters men- 

 tioned in generic key and having the head more strongly rounded 

 and the last joint of maxillary palpi smaller than in Lappus. 

 Three closely allied sjx'cies may oecur in Indiana, though but two 

 have been taken. 



KEY TO INIHANA SPECIES OF MALPORUS. 



(/. Elytral ]tunctures distinct tlirongliont the disk, tine and remote toward 



apex, closer and coarse before the middle. 



1). Thorax very strongly constricted; body throughout more sparsely 



punctate: elytra without an apical pale spot. eormicarius. 



hh. Thorax nuich less strongly constricted; body more densely punctate; 



elytra more parallel, the pale crossband less basal, each with an 



apical pale spot. 2484. cinctls. 



aa. Elytral punctures limited to tlie sub-basal trnnsverse impression, which 



is strong. 12485. properus. 



2484 (7041). Maepobis cinctus Say, Journ. Phil. Acad. Nat. Sci., III. 



1824, 278; ibid. II, 105. 

 Dark reddish-brown, shining; elytra Idack or piceous, reddish at base, 

 and with a pale, narrow crossband, interrupted at suture, in front of mid- 

 dle, and usually a faint pale spot at margin of tips. Thorax narrower 

 than head, much longer than wide, strongly constricted on sides behind the 

 middle; the larger front lobe globose and sparsely punctured, the hind one 

 rather coarsely and densely ]iunctured. Elytra with disk feebly, trans- 

 versely impressed on basal third, each witli a distinct hump near suture 

 in frcmt of pale bar; surface punctui'ed and with erect set:e as mentioned 

 in keys. Length 3-3.8 mm. 



Throughout the State; scarce. February 11-July 24. Occurs 

 beneath logs and rubbish, especially in sandy places near water. 

 Several dark specimens with apical pale spot lacking may be for- 

 ^nicarius Laf., hut I am unable to satisfactorily separate them as 

 distinct. That species is said to occur from Rhode Island to Iowa.

 More slender and somewhat ]>aler than ciiictiis; (>yes larger and more 

 convex; antennte more slender. El.vtra with basal transverse impression
