216 MEMOIRS ON THE COLEOPTERA 



Family SPONDYLID^. 



Subfamily PARANDRIN.E. 



Parandra Latr. 



The species of this genus are numerous and widely distributed 

 but in many cases are difficult to discriminate. There seem to be 

 three specific American forms included in the material before me, 

 not including polita Say, which I do not have at present, except in 

 a series of six examples of the Central American form, named 

 cylindrica Thorns., which is said by Horn to be identical with polita; 

 it is very elongate, subdepressed and parallel ; the other three species 

 as represented by the male may be separated as follows: 



Carina along the anterior face of the hind tibiae much nearer the inner 

 than the outer edge; eyes well developed, fully two-fifths as long as 

 the median length of the head; color dark testaceous throughout. 

 Body very stout, finely and sparsely punctate; head very wide, but 

 little narrower than the prothorax, the mandibles arcuate, slightly 

 shorter than the head; antennae barely as long as the width of the 

 latter; prothorax three-fourths wider than long, obtrapezoidal, 

 about as wide as the elytra, the latter barely one-half longer than 

 wide. Female more elongate than the male, with less transverse 

 and more parallel prothorax and much smaller head and mandibles. 

 Length (of, 9) 17.5-18.5 mm., width 6.3-6.6 mm. Indiana. 



ampliceps n. sp. 



Carina medial; eyes very much smaller, between a third and fourth as 

 long as median line of the head 2 



2 Color dark piceous throughout, parallel, elongate, finely, sparsely 

 punctate; head moderate, distinctly narrower than the prothorax, 

 the mandibles more slender, arcuate, shorter than the head; antennae 

 much longer than the width of the latter; margin of the epistoma 

 gradually and feebly anteriorly prominent medially and in the 

 form of a broad cusp; prothorax but little more than one-half wider 

 than long, obtrapezoidal; elytra three-fourths longer than wide. 

 Length (cf 1 ) 15.2 mm.; width 4.6 mm. New York., .brunnea Fabr. 



Color pale brownish-testaceous throughout, very variable in size, 

 stouter than brunnea, the antennae not quite so long as the width 

 of the head, the mandibles nearly as in the two preceding; epistomal 

 margin abruptly dentiform at the middle; prothorax a little wider 

 than the head, two-thirds to three-fourths wider than long, obtrape- 

 zoidal; elytra two-thirds longer than wide. Female differing as 

 in the female of ampliceps. Length (cf, 9) 9.4-16.8 mm.; width 

 3.0-5.6 mm. Pennsylvania and westward. Abundant. 



gravidula n. sp. 



In addition to these more definite forms, there are two specimens 

 at hand that are aberrant; one, a female, exactly like the ordinary
