NEW SPECIES OF COLEOPTERA (FAM. CLERIDAE) 



FROM THE PHILIPPINE AND NEIGHBORING 



REGIONS, COLLECTED BY PROF. 



CHARLES F. BAKER. 



BY EDWARD A. CHAPIN. 



The new species of Cleridae herein described form part of 

 a collection made by Professor Charles Fuller Baker, of the 

 College of Agriculture, University of the Philippines, Los Bafios, 

 P. L, on different islands of the Philippine archipelago and 

 Borneo. The collection is exceptionally rich in species of the 

 genera Callimerus and Tenerus. All of the forms characterized 

 in this paper are referable to the tribe Tillini. The types are 

 all in the author's collection. 



1. Tillus mindanensis, n. sp. 



Form and size of T. notatus Klug. Black, elytra with a central longi- 

 tudinal brownish plagia and a transverse ivory spot on either side. Head 

 black, punctuation very fine, almost invisible, antennae eleven segmented, 

 strongly serrated, the three basal segments piceous. Mouthparts, except for 

 the mandibles winch are black, piceous. Thorax barrelshaped, strongly con- 

 stricted behind, shining, punctures fine and sparse. Scutellum densely 

 pubescent with white hairs. Elytra with coarse punctures in rows on the 

 basal half, finely and irregularly punctured toward the apex. Near the 

 scutellum, between the first and second rows of punctures there is a deep 

 longitudinal pit, as long as two spaces between punctures. The elytra are 

 black except for the central brown portion bounded as follows : at the base 

 by the fourth row of punctures, thence toward the apex to about basal 

 fourth where it is suddenly narrowed to the second row. At about the 

 middle it suddenly widens in a triangular lateral expansion, reaching the 

 lateral transverse ivory spot. This spot commences at the fifth row of 

 punctures and reaches the lateral margin. The brown plagia disappears
