National Museum through the kindness of Andre Audant, of the 

 Service Technique in Haiti. 



I liave no record of the habits of this species (xcept that it has 

 been taken principally at elevations of 3,000 to 4,000 feet. 



10. XANTHOLINUS MORRISONI, new species 



Description. — Black, elytra and tip of abdomen rufotestaceous. 

 Head scarcely longer than wide; eyes not at all prominent; gradu- 

 ally wider posteriorly but with basal angles broadly rounded; an- 

 tenna! grooves feebly impressed but distinct and even, punctate 

 apically, and with a fine oblique groove from each antennal base; 

 ocular groove absent; with umbilicate punctures very scattered and 

 of uneven sizes, absent from center of vertex; with minute punctu- 

 lae between punctures, but without ground sculpture. Pronotum 

 one-fifth longer than wide, widest in anterior third, somewhat 

 emarginately narrowed to rounded base; with smooth midline out- 

 lined by two irregular series of five or six punctures, without a 

 distinct lateral series but with a few scattered punctures; without 

 ground sculpture. Elytra moderately coarsely punctate, but serially 

 only at sides of disk ; surface vaguely coriaceous but without ground 

 sculpture. Abdomen with sparse but not very fine submuricate punc- 

 tures, and indefinite transverse strigulae. Length, 71^ mm. 



Type locality. — Trinidad, River Estate, 8 miles northwest of 

 Port-of -Spain. 



Types!— Holotype^ U.S.N.M. No. 52436, collected on October 16, 

 1918, by Harold Morrison. 



Records. — The following is the only record known to me: 



Trinidad: River Estate (Morrison, in U.S.N.M.). 



Specimens examined. — I have seen only the unique type. 



Remarks. — This species is similar to the description of hydro- 

 cephalus in many respects but seems to be amply distinct by the 

 following: The much greater size, the different coloring of the 

 abdomen, the head only slightly dilated behind the eyes, and the 

 dorsal pronotal series of five or six punctures. 



I have no record of its habits. 



11. XANTHOLINUS HAITIUS, new species 



Description. — Black, sometimes picescent at edges of sclerites. 

 Head one-third longer than wide, parallel, basal angles moderately 

 rounded; antennal grooves very feeble, ending in a semicircle of 

 large punctures, with an additional fine oblique groove from base 

 of antennae, ocular grooves absent; with rather large impressed 

 umbilicate punctures separated by one to two times their diameter,
