 Eurycotis manni new species (Plate XIV, fig. 15.) 



This striking new form belongs to the section of the genus 

 formed by the species of black color with decidedly lateral lobi- 

 form tegmina. It is distinctly larger than any of the forms to 

 which it is related and the body coloration is entirely black. No 

 detailed comparison of the genital characters with those of sev- 

 eral of the allies is possible, as the latter are unknown in the 

 male sex, but the several diagnostic characters given above are 

 amply sufficient to distinguish the new form.

Size rather large; form elliptical, subdepressed; surface moderately polished. 

 Head projecting moderately cephalad of the pronotum; occiput and eye out- 

 line regularly arcuate; interspace between the eyes very broad, nearly three 

 times as great as the depth of the eye; face somewhat flattened; eyes not greatly 

 elongate, dorsal margin sinuate where covered by the pronotal margin; an- 

 tennae at least two-thirds as long as the body, proximal joint nodulose proxi- 

 mad, second joint almost twice as long as the fourth, third joint slightly longer 

 than the proximal one; palpi with third joint slightly longer than the fourth 

 one, fourth joint elongate conical, fifth joint subequal to the fourth joint, mod- 

 erately broad, compressed. Pronotum semiovate, narrow cephalic margin 

 subtruncate, broad caudal margin bisinuato-truncate, lateral margins arcuate 

 divergent caudad, cephalo-lateral angles narrowly rounded rectangulate; 

 surface with poorly defined shallowly impressed pattern. Mesonotum and 

 metanotum with faintly bisinuato-truncate caudal margins. Tegmina faintly 

 more than half as long as the pronotum, reaching to the caudal margin of the 

 mesonotum, decidedly lateral, separated by two and one-half times their 

 individual width, their length slightly greater than their width; costal margin 

 gently arcuate, apex costal in position, rotundato-subacute, sutural margin 

 gently arcuate, disto-sutural angle moderately rounded, distal margin moder- 

 ately oblique arcuato- truncate; marginal field moderately defined; venation
