METACHROMA.—EUMOLPUS. 235 
9. Metachroma bipunctata. 
Black, the basal joints of the antenne and the head fulvous; the thorax fulvous, with two black spots, 
closely punctured; elytra flavous, strongly punctate-striate, the suture and a small spot below the 
middle, black. 
Length 23 lines. 
Head finely and closely punctured on the vertex, the latter stained with piceous at the sides ; the clypeus mor 
strongly and remotely punctured, its lower margin moderately strongly emarginate ; labrum fulvous ; 
mandibles black; antennz with the lower six joints fulvous, the others black; thorax transverse, the sides 
strongly rounded, the anterior angles dentiform, the surface very closely punctured, the punctures more 
distinct at the sides than on the disc, the latter fulvous, with two elongate, rather distantly placed, black 
spots; scutellum piceous; elytra flavous, very strongly, deeply, and regularly punctate-striate, the punc- 
tures piceous in colour and distinct to the apex, the interstices minutely punctured, and at the sides 
rather strongly costate, the suture and a small spot on the fifth interstice below the middle black ; 
underside black; legs fulvous. 
Hab. Mexico, Vera Cruz (Hége). 
10. Metachroma quadrimaculata. 
Fulvous, the antenns (the lower four joints excepted) black; thorax very finely punctured, with four black 
spots, placed transversely ; elytra rather finely punctate-striate, the sutural and lateral margins, an oblique 
stripe at the shoulder, and another near the apex, black. 
Length 13 line. 
Head with a black spot in the middle, rather coarsely and closely punctured on the vertex, the punctures some- 
what elongate, the clypeus strongly and irregularly punctured ; antennx proportionately slender, black, 
the lower four or five joints pale fulvous; thorax of the same shape as in M. ornata, very finely and 
remotely punctured, the dise with four elongate equidistant black spots; scutellum with a few fine 
punctures; elytra more finely punctured than in M. ornata, with a distinct lateral depression below the 
base, the punctures becoming indistinct towards the apex, each elytron with an oblique short stripe 
extending from the shoulder towards the middle, and another (longer or shorter) spot or stripe below the 
middle, the suture and lateral margin (narrowly) black, the sutural stripe in some specimens being widened 
into a spot below the scutellum; underside and legs fulvous. 
Hab. Mexico, Cuernavaca in Morelos (H. H. Smith). 
EUMOLPUS (p. 172). 
Eumolpus surinamensis (p. 172). 
To the localities given, add:—Mexico, Northern Sonora (Morrison), Presidio de 
Mazatlan (Forrer), Ventanas in Durango, Huetamo in Michoacan, Tonila in Colima, 
Tapachula in Chiapas (Lége), Tepetlapa, Mescala, and Acapulco in Guerrero, Puente 
de Ixtla in Morelos (H. H. Smith); Panama, David, Bugaba (Champion). 
The specimens from Sonora differ from all those from the cther localities in having 
the oblique lateral grooves which separate the clypeus from the face obsolete, and it is 
possible that they represent a closely allied species; but in the absence of other marks 
of distinction, it is not advisable to separate these forms.
