New and little-known Lagriidae and Pcdilidae. 239 



long, erect, bristly hair! intermixed, the restitute of the under sur- 

 face dense and whitish; reddish-brown, the head rufescent, the 

 antennae, palpi, and legs (except the anterior knees, the intermediate 

 and posterior tibiae, a patch on the posterior femora, and the first 

 posterior tarsal joint, which are infuscate) testaceous. Head short, 

 broad, densely punctulate, rounded at the base, the occipital groove 

 broad, extending forward to nearly as far as the middle of the eyes, 

 the latter very large ; antennae rather short, not very slender, joints 

 9-11 elongated and thickened. 11 Blightly longer than 10; maxillary 

 palpi moderately stout, joint 4 cultriform. Prothorax long, convex, 

 broader than the head, arcuately dilated anteriorly and narrow at 

 the base (thus appearing cordate), densely scabroso-punctate, the 

 basal groove shallow and very near the margin. Elytra sinning, 

 long, somewhat convex, subparallel in their basal half; closely 

 punctulate, without definite striae (the- suturaland submarginal lines 

 excepted), but with rows of minute punctures down the disc to be- 

 yond the middle, the interstices broad, and with a line of minute 

 granules along their outer edge. Legs long, stout; basal joint of 

 anterior tarsi as broad as the tibia. Penis-sheath very long, slender, 

 compressed, blunt at the tip; the lateral lobes of the aedeagus long, 

 slender, acuminate, along, curved, slender, spiniform process arising 

 from near the base of each of them. 

 Length 6 mm. 



Hob. Colombia, ? Bogota (ex coll. F. Bates). 



One male. This insect seems to be nearly related to 

 M. goudoti and f nuclei, Laf., from Colombia and Venezuela 

 respectively, but it cannot be identified with either of them. 

 Compared with the Central-American M. princeps, Champ., 

 the present species is narrower and more convex, and it 

 has the elytra less densely punctate, the prothorax more 

 dilated anteriorly, the head rounded (instead of truncate) 

 behind, and the occipital groove longer. M. fissiceps is 

 recognisable from its American allies by the long, convex, 

 cordate prothorax; the short, deeply cleft, basally rounded 

 head; the large eyes; the granulate, non-striate, 



shining elytra f and the elongate, robust body. The genital 

 armature is wholly different from that of M. scabrida and 

 incana, the only American mem hers of the genus as yet 

 dissected by me.
