470 - FAUNA HAWAIIENSIS 



We have one specimen, a male. It comes nearest to E. spretiis, but appears to be a 

 smaller and flatter insect, and to be definitely distinguished by the antennae. Varieties 

 o{ E. omalioides may resemble E. brevicollis in colour,, but the sculpture is different and 

 the antennae not quite so short. 



Though we have only one example from Waianae, I have no doubt of the dis- 

 tinctness of this species. An individual from near Honolulu though excessively immature, 

 and consequently unnaturally pallid and depressed, has the same structural characters 

 and probably pertains to this species.

Sat latus, aequalis ; prothorace crebre baud profunde punctato, ad basin angustato, 

 disco obsolete quadri-impresso, angulis anterioribus parum rotundatis ; elytris baud 

 profundius sulcatis, ad latera sat late explanatis ; abdomine sat subtile punctato. Long. 

 2)\ mm. 



This species is distinguished by its broad form and relatively even surface, the 

 elytra being scarcely at all impressed. The thorax is relatively longer than in E. brevi- 

 collis : its punctures are rather shallow with radiating striae. The antennae are not 

 conspicuously shortened as in E. brevicollis. Abdominal punctuation not coarse. 

 Male supplementary segment rounded in outline. We have two specimens, a male 

 and a female.

This species was described from a single very good male specimen from Oahu. 

 We have now a series of fifty specimens. In the original diagnosis the insect was 

 described as " testaceus, fusco-variegatus, opacus, parce pubescens." Our series would 

 be more correctly described as " flavo-ferrugineus, fusco-variegatus, leviter nitidus, 

 crebre pubescens." The colour varies considerably. Many specimens are light, with a 

 dark band down the centre of the prothorax and of the abdomen, and small dark marks 

 close to the fimbriae of each abdominal segment. The scutellum is almost always dark. 

 The elytra are usually somewhat darker, in some specimens very dark. In a few 

 specimens, the distribution of dark and light colours on the elytra is such as to produce 

 a light patch on the posterior inner part of either elytron, thereby approaching the 

 condition found in several closely-allied species, and most marked in the van dimidiatus 

 of E. inacqiialis. The cross-striations between the furrows of the elytra are conspicuous.
