146 ~=Buackpurn AND SHARP—On some New Species and Genera of Coleoptera. 
Erorevs (nov. gen. ). 
This generic name is proposed for a very minute insect of rotund form, 
allied to Hypodacne and Euxestus. The head is broad and very short; and 
the small eyes, consisting of a few coarse facets, are placed as it were on a 
prominent free angle at the front of the side; the antenne are short and 
apparently ten-jointed, the basal joint rather large, the second smaller, third 
not elongate, fourth to eighth small and short, ninth and tenth forming a large 
loosely articulated club. The middle and hind cox are very widely separated, 
the front ones only moderately ; the metasternum is much produced in the middle 
between the coxe, so that it touches the prosternum, and no portion of the meso- 
sternum is visible. The tarsi are small, four-jointed, the three basal joints not 
differing much, the third simple, the fourth elongate; the hind tarsi are longer 
and more slender than the others, and their basal joint is more elongate. 
DAS: 
Eidoreus minutus, n. sp.—Rotundato-ovalis, sat convexus, nitidus, testaceus, 
glaber, fere impunctatus; antennis brevibus, clava laxe bi-articulata. Long. 
1 m.m. 
Antenne about as long as the thorax ; this strongly transverse, closely applied 
to and continuous with the elytra, truncate at the base, a little narrowed towards 
the front margin, shining and almost impunctate, as are also the elytra. 
Two fragmentary specimens have been sent me as No. 336. 
Fam. COCCINELLIDA. 
ScyMNUS. 
Scymuus vividus, n.sp.—Lzete rufus, pectore, abdomine, prothorace posterius 
in medio, elytrorumque plaga magna, communi, triangulari, nigris, femoribus 
posterioribus et intermediis fuscis; elytris fortiter punctatis, pubescentia pallida 
conspicua vestitis. Long. 2} m.m. 
Antenne and palpi yellow. Head and thorax yellowish-red; the latter in the 
middle, with a very large black mark extending nearly to the front margin; not 
closely and rather obsoletely punctured. Elytra bright red, with a large trian- 
gular mark black; the base of the triangle occupies the greater part of the width 
of the elytra at the base, and the apex is placed on the suture near the extremity ; 
the punctuation is not dense, but is rather coarse, especially on the black portion. 
Beneath, the sides of the thorax. are pale, the middle blackish, the breast and 
ventral segments black, the epipleurz bright yellowish-red.
