HELOTA LUGUBRIS. 165 
NOTE XIV. 
ON THREE SPECIES OF THE COLEOPTEROUS 
GENUS HELOTA 
BY 
C. RITSEMA Cz. 
Helota lugubris Rits. 9. 
No doubt the female Helota from Lakhon (Siam) in the 
Paris Museum, determined by me in 1897!) as Helota 
Vandepolli Rits., is a female specimen of the recently 
described Helota lugubris from Laos (see page 57 of this 
volume). 
The quoted Q, which is now before me and which 
measures 12 mm. in length, agrees with the © of lugubris 
except in the following points, which certainly are sexual 
differences. 
Elytra. The apices are not broadly conjointly rounded 
but bluntly pointed and more widely dehiscent at the 
suture. The angular notches on the outer margin of the 
apical fourth are less deep. The apical portion of the 6th 
interstice is not strongly raised and therefore not conspicuous. 
Abdomen. The apex of the last ventral segment is 
broadly rounded; the surface of this segment is flat, if not 
faintly concave. 
Legs. The anterior tibiae are almost straight, the 
posterior femora straight, the posterior tibiae without tuft 
of hairs at the end.
