AMPHICROSSUS. 349 
it is remarkable that the species are excessively similar to one another, though the male 
secondary sexual characters afford a satisfactory means of distinguishing them. 
1. Amphicrossus horni, sp.n. (Tab. XI. fig. 5, 3.) 
Rotundato-ovalis, sat convexus, supra fusco-testaceus, capite nigricante, antennis nigris, basi testaceo, pedibus 
testaceis ; pube depressa flavescente vestitus, corporis limbo longius ciliato. 
Long. 32-5 millim. 
Hab. Guatemata, Teleman, Chacoj, San Isidro (Champion). 
Rather variable in colour, and occasionally presenting the appearance of having one or 
two pallid testaceous marks at the base of each wing-case; readily distinguished from all 
our Nitidulide by the long and conspicuous fringe with which the sides of the thorax 
and elytra are ornamented. The male has an erect pencil of sete on each wing-case 
not very far from the suture, these pencils being widely separated at their extremities. 
Mr. Champion procured a good series of this species at the sap exuding from trees. 
It is extremely similar to the North-American A. ciliatus; but the marginal fringe of 
the body is considerably longer, the punctuation of the upper surface is finer, and the 
terminal ventral segment in the male is differently formed. I have much pleasure in 
naming the species after the well-known American savant, who has been so kind as to 
forward me a specimen of A. ciliatus for comparison. 
We figure a small male found by Mr. Champion at Teleman. 
2. Amphicrossus limbatus, sp. n. 
Rotundato-ovalis, sat convexus, piceus, crebre punctatus, parum nitidus, pube depressa flavescente vestitus, 
corporis limbo breviter ciliato; antennarum basi pedibusque rufis. 
Long. 3-5 millim. 
Hab. Guatemata, Chiacam, Teleman (Champion). 
Antenne with large and dark flat club. Head densely punctate. Thorax finely and 
more sparingly punctate, the hind angles very broadly rounded, the base not margined. 
Elytra finely punctate, sparingly pubescent, with series of distant sete among the 
pubescence. Male with the two pencils of sete on the disc of the elytra placed very 
close to the suture, so that their tips touch one another. 
We have received only one pair of this species. Besides being darker in colour and 
having the cilie surrounding the body shorter than in A. horni, it has the middle of 
the prosternum straighter than in the other species, that is to say, the plane of the 
front part being less bent upwards differs very little in direction from the plane of the 
prosternal process. The male of A. limbatus has the process at the end of the last 
ventral plate elongate, and widely separated from the rest of the plate, the tubercle 
preceding it broad and very prominent.
