Ochresthes citrinus (p. 51). 
According to examples (one of which is from Puebla), no doubt authentically named, 
in the Sallé collection this species resembles O. sommeri in the elytral markings, which 
consist of two twin dusky fascie enclosing spaces of a lighter ochreous than the ground- 
colour, one pair a considerable distance from the base (the basal space being quite free 
from dusky lines), the other pair at a similar distance from the apex; the difference 
between the two species is that the basal fascie in 0. citrinus reach from the margin 
nearly to the suture, and are sharply triflexuous, in O. sommeri they form a transversely 
oval dusky ring enclosing a rounded ochreous spot. ‘There is, however, an important 
structural difference relatively between the two species—the elytra in O. citrinus being 
much longer and obliquely sinuate-truncate, with acutely produced external angles ;. 
in O. sommeri they are broadly and transversely truncated. 
Specimens labelled O. z-littera in the Sallé collection do not differ in the slightest 
from O. citrinus, but they do not agree with Chevrolat’s description. 
Ochresthes pollinosus (p. 51). 
To the localities given, add :—Mexico, Jalapa (Hége), Chiapas (Sallé); GuaTEMALA, 
Mixco 5500 feet (Champion); Panama, Tolé, Pefia Blanca (Champion). 
Found on the similarly coloured flowers of small low-growing plants in open sunny 
places, often in the sugar-cane fields (Champion). 
Ochresthes cristoforii (p. 51). 
Specimens of this species in the Sallé collection are labelled as from Cuernavaca. 
Ochresthes tomentosus (p. 52). 
The exact locality of this Mexican species is Puebla, according to the Sallé collection. 
Ochresthes viridiventris (p. 52). (Tab. XXI. fig. 5.) 
We now give a figure of the unique type of this species. 
14. Ochresthes umbratilis. (Tab. XXI. fig. 3.) 
Quoad formam 0. obliquo simillimus, sed differt colore fusco-ochraceo signaturisque fuscis elytrorum indi- 
stinctis. Valde elongatus, elytris apice singulatim acuminatis, vel ad suturam conjunctim emarginatis ; 
fuscescenti-ochraceus, subtus sulphureo-cinereus; thorace disco obscuriori; elytris utrinque fasciis plus 
minusve vagis quatuor fuscis, quarum duo oblique ante medium maculam elongatam pallidiorem includent 
duoque post medium indistincte maculam juxta suturam pallidiorem amplectent ; antennis (scapo nigro 
excepto) pedibusque piceo-nigris. 
Long. 5-8 lin. 
Hab. Guatumata, Quezaltenango 7500 to 8500 feet (Champion).
