slightly impressed in front and without any strong constriction, the 

 foveae hardly visiiile, the clothing denser along the sides. Elytra at the 

 base as wide as the pronotum. the humeral angles not sharp, hut fairly 

 distinct, the punctures on the basal portion dense, distinct in some 

 aspects and tending to run into one another. There is hardly any im- 

 pression between the scutellum and the humeral angles, the elytra being 

 of simple form and short, about one and a third times the length of the 

 pronotum. The basal abdominal segment beneath has the punctures on 

 the middle portion very feelile or obsolete. Length, male, 2.5 mm. 



Hab. jMiUii, lao Valley, Sept., 1918, on Euphorbia Jiooheri 

 irdcgrl folia (J. C. Bridwell). Described from a single male. 

 When I tirst examined this species it reminded me of the very 

 differently colored (black) P. hreviformis of Lanai, but on 

 comparing the two, I find the differences of structure (antennal 

 joints, pronotum, etc.) so great that they do not appear to be 

 closely allied. 



Proterhinus asteliae n. sp. 



A red species, with the antennae entirely red, the head and pronotum 

 with golden squamosity (fading to white) ; the clothing of the elytra 

 broken up into lines or spots, being variable in extent, so that they are 

 prettily maculate, the bare parts being often black or dark, but sometimes 

 red. Remarkable amongst the species with simple humeral angles to the 

 elytra for the great length of these. The color and maculations resemble 

 those of P. pteridis, but that is a still narrower insect, with totally dif- 

 ferent antennae. 



Antennae of moderate length, about three-fourths the length of the 

 elytra, appearing rather short from the elongation of the insect. Second 

 joint as long or longer than the fourth and much more robust, basal 

 joint of the club much less wide at the apex than the second, but notably 

 longer and wider than the last funicle joint. Rostrum of the female 

 very polished, and the punctate lines very feeble. Pronotum somewhat 

 narrow, usually appearing considerably less wide than the widest part 

 of the elytra, the posterior impressions not deep and sometimes obsolete. 

 Elytra twice or even more than twice the length of the pronotum, and 

 about twice as long as their width at the base ; they have coarse, deep 

 punctures, generally appearing to form rows on a large part at least 

 of the surface. The erect setae are short and sparse, white, and in dorsal 

 aspect will be noticed on each side of the suture towards the apex. 

 Basal abdominal segment- with the punctures feeble or obsolete. Length, 

 male and female, 2.5-3 m"i-
