COLEOPTERA 153 



(4) Hctcranipluis lialcakalae, sp. nov. 



Piceus vel rufo-piceus, rostro, antennis pedibusque rufescentibus. Rostrum rugoso- 

 punctatum, parte postantennali carinatim compressa. Pronotum subgrosse (antice 

 quam postice minus dense) punctatum, sat elongatum, minus latum, dorso juxta basim 

 leviter vel vix evidenter impressum. Elytra sat elongata, striata, striis parum fortiter 

 nee confertim punctatis, parce usque ad basim pubescentia. Long, (rostr. incl.) 6 — 7 mm. 



The general appearance and form of this species is that of H. foveatiis Shp., but 

 it is easily distinguished by the fact that it is more elongate, both the prothorax and 

 elytra being narrower, and the former has only a shallow, sometimes hardly perceptible, 

 impression near the base, and the punctures of the elytral striae are finer and more 

 feeble. It is also very closely allied to the following species. 



Hab. Maui, Haleakala (5000 ft.) ; three examples ; taken from dead logs. 



(5) HcterainpJms /rater, sp. nov. 



Piceus vel rufo-piceus, rostro, antennis pedibusque plus minusve rufescentibus. 

 Rostrum rugoso-punctatum, parte postantennali carinatim compressa. Pronotum grosse 

 punctatum, postice juxta basim profunde foveatum. Elytra minus lata, usque ad basim 

 parce pubescentia, striis minus fortiter punctatis. Long, (rostr. incl.) 6 — 7 mm. 



Somewhat intermediate between H. haleakalae and H. foveatns, the base of the 

 prothorax having a strong round impression. It is a narrower and more elongate 

 insect than H. foveatus, and has the striae of the elytra less strongly punctured. From 

 H. haleakalae it differs in the strong impression on the prothorax, and in the fact that 

 the shoulders of the elytra are capable of being more closely applied to the base of the 

 prothorax. The two examples taken do not agree well together, the one being more 

 bulky than the other, and having the thoracic puncturation coarser, while the punctures 

 of the striae of the elytra are finer and less closely placed. The smaller example has no 

 impression on the apical ventral segment of the hind-body, whereas in the larger this 

 segment is distinctly impressed, as is also the case with all the individuals of the 

 preceding species. 



Hab. Maui, Haleakala (5000 ft.) ; very rare. 



(6) HeterampJms molokaiensis, sp. nov. 



Piceus, antennis, rostro pedibusque plus minusve rufescentibus. Rostrum distincte 

 punctatum, parte postantennali carinatim compressa. Pronotum angustum, elongatum, 

 antice angustatum, vix grosse punctatum, parum evidenter pubescens. Elytra pronoto
