Luzon, Laguna, Mount Banahao. 



This insect was previously known only from the Malay Pen- 

 insula. In my redescription of the genus Porta ^ I compared it 

 with the genus Vertomannus Dist. "as redescribed by Breddin," 

 but I have since found that Vertomannus Bredd. is distinct from 

 Vertomannus Dist. and forms another genus, which I have re- 

 cently described under the name Omacrus. 



Genus TACHYTATUS novum 



Body elongate. Head exserted, as long as broad and as broad 

 as anterior pronotal lobe, somewhat shorter than pronotum, 

 seen from above rhombic, postocular part a little shorter than 

 anteocular part and subequal in length to eye, subsinuately rather 

 strongly narrowed from eyes to base, eyes rather large but mod- 

 erately prominent, ocelli placed as far from each other as from 

 eyes, vertex one-half broader than an eye, antennif erous tubercles 

 immediately before the eyes; antennae very slender, as long as 

 or a little longer than body, first joint somewhat shorter than 

 head and passing its apex by two-thirds the length of the joint, 

 second more than twice the length of first, third a little shorter 

 than second, fourth subequal to second ; buccula very short, ros- 

 trum reaching middle of mesosternum, first joint not nearly
