horridus, Champ., £, but with more approximate eyes, the 

 maxillary palpi stouter, and with a longer terminal joint, 

 the elytra shorter, more depressed, and more coarsely 

 punctate posteriorly ; the vestiture a little sparser.* The 

 head and eyes are shaped much as in the Brazilian E. 

 reichei, Laf., as figured by its describer. 



2. Eurygenius arizonensis, n. sp. 



(J. Elongate, depressed, moderately shining, clothed with rather 

 long, fine, decumbent, cinereous pubescence which is here and there 

 condensed into small patches on the elytra, the head and prothorax 

 with intermixed long, soft, erect hairs; piceous, the elytra] epipleura 

 and tarsal claws, and sometimes the antennae and palpi in part, 

 testaceous. Head broad, densely punctate, feebly developed behind 

 thegeyes, the latter extremely large, slightly sinuate in front, and 

 separated by a little less than the width of one of them as seen 

 from above; antennae rather short, very slender, joint 2 obconic, 

 stouter than 3, 3-10 decreasing in length, 3 twice as long as 2, 11a 

 little longer than 10; terminal joint of maxillary palpi narrow, long, 

 subcultriform. Prothorax nearly as wide as the head, along the 

 median line about as long as broad, rounded at the sides anteriorly 

 and gradually narrowing thence to the base, the hind angles obtuse, 

 the collar sharply defined ; closely, conflucntly punctate, without trace 

 of median groove. Elytra moderately long, very gradually narrowed 

 from the base, coarsely, confusedly punctate. Fifth ventral segment 

 emarginate at the tip. Penis-sheath sagittiform at the tip beneath. 

 Tibial spurs short. Penultimate tarsal joint very small, triangular. 



Length 52—7, breadth 1-J — 2 mm.

Four males, sent me by Dr. Skinner in 1913, and sub- 

 sequently presented to the British Museum. Smaller and 

 less elongate than E. mexicanus, Champ., the head much 

 less developed behind the eyes, the latter extremely large, 

 the antennae shorter, the palpi more slender, the elytra 

 more shining and not so closely punctate. The Guatemalan 

 E. crinilus has the head broader at the base than in the 

 present species and the prothorax canaliculate. E. ari- 

 zonensis approaches Casey's section Retocomus; but as the 



* A smaller and narrower q (now without antennae), from the 

 Bowring collection, labelled " X. Hebrid.," with the eyes less approxi- 

 mate and not so large, probably belongs to the same species : this 

 insect is almost certainly of American origin.
