336 THE SPECIES OF EUERYTHRA. 



from the tip of subcostal, 7 giving off first 10 tlieu S, from wliich 

 9 branches close to the tip — that is to say veins 7 to 10 are on a single 

 stalk ; 11 from subcostal rather close to the end of the cell, thence to 

 costa. Costal as usual. Cell closed by a fine cross vein. Secondaries 

 freuate, the costal vein icanting. Two internal veins, the outer very 

 faint. Median vein giving rise to 2 at the outer third, 3 and 4 at the 

 end of cell ; 5 is from the cross vein, close to 4. The subcostal branches 

 into C or 7 some distance beyond the cell and these veins are therefore 

 unusually short. The absence of tha costal vein recalls the so-called 

 Zyf/a'nid families, but is not so usual in the Arctiidce where it is usually 

 from the subcostal at a variable distance from base. 



The genitalia of the male are somewhat distinctive, the supra anal 

 hook is inflated at the angle of the bend, and viewed laterally has some 

 resemblance to a bird's head. The side pieces are broad, semi-cylindrical 

 corneous toward tip where the upper angle is produced into a rather 

 long pointed somewhat twisted projection — there is some difference in 

 the species which will be pointed hereinafter out.

The brief description at the beginning of the article is sufficiently 

 characteristic to obviate the necessity of a detailed enumeration of pe- 

 culiarities. It remains only to add that the palpi are crimson as are 

 the front coxae. Inner side of front femora and tibiae dark. On the 

 underside the primaries generally show a faint reproduction of the 

 markings of upper side. The tip of the side pieces of the $ is in this 

 species considerably drawn out, corneous and acute, somewhat curved. 

 A reference to the figure will show the structure at a glance. The 

 rounded i)rojection at the lower angle is membraneous in texture. 



E. trimaculata, sp. uov. 



Head and thorax white, orbits of eyes and the vestiture of palpi 

 bright red. Abdomen white, the segments ringed with bright red 

 (crimson) of variable width. In the 2 the red is sometimes very faint 

 orange, covered with white scales. In the $ , on the contrary, the pre- 

 dominating color is sometimes red or crimson and the abdomen appears 

 white bandetl. The basal segments are always more narrowly red- 

 ringed in both sexes, and rarely they are altogether absent at this 

 l)oiut. A row of black dorsal spots, which are, however, often wanting. 

 Primaries with an umber brown or blackish fascia of variable width 

 near the base — broadest at costa, outwardly oblique to the submedian 

 interspace, and there usually terminated ; occasionall}' there is a nar- 

 rower prolongation, inwardly oblique to the internal vein. Another 

 short'baud of similar color from the costa near apex, inwardly oblique 

 to vein 5. A short upright band from tlie inner mart:in near anal angle 

 to vein 2. In some specimens there is a double spot at the end of the 

 discal cell. The veins where they cross the brown bands are marked 

 with yellow scales. Secondaries pure white, immaculate. Beneath, the
